Many countries throughout the world have published standards or recommendations for proper tire repairing. To ensure a proper used tire repair: Your used tire should always be demounted from the wheel and inspected for damage or unsafe conditions, which might make the tire non-repairable. The used tire should then be repaired by removing the object that caused the damage, then drilling out the injury to remove all damage to the tire. Based on the size of the injury, your tire repair specialist will then determine how the tire should be repaired. Typically, a "nail hole" injury is any injury 1/4" (6mm) or smaller in passenger tires. Injuries larger than 1/4" (6mm) are considered to be "section repairs" on passenger tires. Injuries larger than 3/8" (9mm) are considered section repairs on light truck and truck tires. A proper tire repair procedure uses a vulcanizing rubber stem to fill the tire injury and the proper sized used tire repair patch to reinforce the inner liner of the tire. Can sidewall or shoulder injuries be repaired? Tire Cross Section Tech's policy is most crown, shoulder and sidewall injuries can be repaired, depending on: The location of the injury The size of the injury Type of tire and speed rating of the tire However, Tech advocates that the tire manufacturer's published tire repair policy for the brand of tire being repaired be strictly followed and adhered to when repairing that particular brand of tire. About Used Tire Service Description Tires are built to withstand more abuse than most of the other parts of your car. After all, your used tires are the only part of your car that actually comes into contact with the roads you drive on. Therefore, it's important that you understand them as much as possible. Fitting a vehicle with tires that have a load rating lower than recommended or loading up your car with too much weight can strain your tires, causing them to wear out faster or even potentially blowout. By the same token, driving your car too fast can also put more strain on your used tires than they can withstand. So just how much weight is too much weight and how fast is too fast? It varies depending on the used tires. Your used tires' weight and speed limits are indicated by the tire service description; a short code located on the sidewalls of your used tires that. This short code, which consists of a two or three digit number along with a single letter, designates just how much weight your used tires are capable of carrying safely and the maximum speed the used tires are designed for. TIRE BALANCE also referred to as used tire unbalance or imbalance, describes the distribution of mass within an automobile tire or the entire wheel to which it is attached. When the wheel rotates, asymmetries of mass may cause it to hop or wobble, which can cause ride disturbances, usually vertical and lateral vibrations. It can also result in a wobbling of the steering wheel or of the entire vehicle. The ride disturbance, due to unbalance, usually increases with speed. Vehicle suspensions can become excited by unbalance forces when the speed of the wheel reaches a point that its rotating frequency equals the suspension's resonant frequency. Zinc tire weight Tires are balanced in factories and repair shops by two methods: static balancers and dynamic balancers. Tires with high unbalance forces are downgraded or rejected. When used tires are fitted to wheels at the point of sale, they are measured again on a balancing machine, and correction weights are applied to counteract the combined effect of the tire and wheel unbalance. After sale, tires may be rebalanced if driver perceives excessive vibration. STATIC BALANCE Static balance can be measured by a static balancing machine where the used tire is placed in its vertical axis on a non-rotating spindle tool. The spot on the used tire with the greatest mass is acted upon by gravity to deflect the tooling downward. The amount of deflection indicates the magnitude of the unbalance. The angle of the deflection indicates the angular location of the unbalance. In tire manufacturing factories, static balancers operate by use of sensors mounted to the spindle assembly. In tire retail shops, static balancers are usually non-rotating bubble balancers, where the magnitude and angle of the unbalance is observed by looking at the center bubble in an oil-filled glass sighting gauge. While some very small shops which lack specialized machines still do this process, they have been largely replaced in larger shops with machines. DYNAMIC BALANCE Dynamic balance describes the forces generated by asymmetric mass distribution when the tire is rotated, usually at a high speed. In the tire factory, the tire and wheel are mounted on a balancing machine test wheel, the assembly is accelerated up to a speed of 300 RPM or higher, and sensors measure the forces of unbalance as the tire rotates. These forces are resolved into static and couple values for the inner and outer planes of the wheel, and compared to the unbalance tolerance (the maximum allowable manufacturing limits). If the used tire is not checked, it has the potential to wobble and perform poorly. In tire retail shops, tire/wheel assemblies are checked on a spin-balancer, which determines the amount and angle of unbalance. Balance weights are then fitted to the outer and inner flanges of the wheel. Dynamic balance is better (it is more comprehensive) than static balance alone, because both couple and static forces are measured and corrected. The dynamic balance can only be conducted if the driver comes to the garage and has the garage check for imbalances. With the existing sensors found in many cars, however, the imbalance can be estimated in real time, as seen in a recent SAE paper: sensors such as the ABS wheel speed sensors were used to detect an imbalanced tire or tires in real time.[1] The physics of dynamic balance Physics of tire imbalance Mathematically, the moment of inertia of the wheel is a tensor. That is, to a first approximation (neglecting deformations due to its elasticity) the wheel and axle assembly are a rigid rotor to which the engine and brakes apply a torque vector aligned with the axle. If that torque vector is not aligned with the principal axis of the moment of inertia, the resultant angular acceleration will be in a different direction from the applied torque. Whenever a rotor is forced to rotate about an axis that is not a principal axis, an external torque is needed. This is not a torque about the rotation axis (as in a driving or braking torque), but is a torque perpendicular to that direction. If the rotor is suspended by bearings, this torque is created by reaction forces in the bearings (acting perpendicular to the shaft). These reaction forces turn with the shaft as the rotor turns, at every point producing exactly the torque needed to keep the wheel rotating about the non-principal axis. These reaction forces can excite the structure to which they are attached. In the case of a car, the suspension elements can vibrate giving an uncomfortable feel to the car occupants. In practical terms, the wheel will wobble. Automotive technicians reduce the wobble to an acceptable level when balancing the wheel by adding small weights to the inner and outer wheel rims. Balancing is not to be confused with wheel alignment. Video explaining the causes of wheel and used tire vibration. Vibration in cars and light trucks occurs for many reasons. Common reasons are poor wheel balance, imperfect tire or wheel shape, brake pulsation, and worn or loose driveline, suspension, or steering components. Occasionally and rarely, one will find foreign material stuck in used tire's tread causing vibration e.g. road tar in summer. Tire rotation or rotating tires is the practice of moving automobile wheels and tires from one position on the car, to another, to ensure even tire wear. USEDTire wear is uneven for any number of reasons. Even tire wear is desirable to maintain consistent performance in the vehicle and to extend the overall life of a set of used tires. By design, the weight on the front and rear axles differs which causes uneven wear. With the majority of cars being front-engine cars, the front axle typically bears more of the weight. For rear wheel drive vehicles, the weight distribution between front and back approaches 50:50. Front-wheel drive vehicles also have the differential in front, adding to the weight, with a typical weight distribution of no better than 60:40. This means, all else being equal, the front used tires wear out at almost twice the rate of the rear wheels, especially when factoring the additional stress that braking puts on the front tires. Thus, used tire rotation needs to occur more frequently for front-wheel drive vehicles. Turning the vehicle will cause uneven used tire wear. The outside, front used tire is worn disproportionately. Cloverleaf interchanges, and parking ramps turn right in left hand drive (otherwise known as right hand traffic) countries, causing the left front used tire to be worn faster than the right front. Furthermore, right turns are tighter than left turns, also causing more used tire wear. Conversely the sidewalls on the right used tire tends to be bumped and rubbed against the curb while parking the vehicle, causing asymmetric sidewall wear. The symmetric opposite occurs in countries that drive on the left. In addition, mechanical problems in the vehicle may cause uneven used tire wear. The wheels need to be aligned with each other and the vehicle. The wheel that is out of alignment will tend to be dragged along by the other wheels, causing uneven wear in that tire. If the alignment is such that the vehicle tends to turn, the driver will correct by steering against the tendency. In effect the vehicle is constantly turning, causing uneven tire wear. Also, if a used tire is under or over-inflated, it will wear differently than the other used tires on the vehicle. Rotating will not help in this case and the inflation needs to be corrected. Car manufacturers will recommend used tire rotation frequency and pattern. Depending on the specifics of the vehicle, tire rotation may be recommended every 8,000 km (5,000 mi).[1] The rotation pattern is typically moving the back wheels to the front, and the front to the back, but crossing them when moving to the back. If the tires are unidirectional, the rotation can only be rotated front to back on the same side of the vehicle to preserve the rotational direction of the used tires. Most unidirectional used tires can be moved from side to side if they are remounted; used tires with asymmetric rims are a rare exception. More complex rotation patterns are required if the vehicle has a full-size spare tire that is part of the rotation, or if there are snow tires. To clarify; the pattern for asymmetrical used tires to be rotated, or positioned, is for the used tires on the driving axle of two-wheel drive vehicles to remain on the same side of the vehicle as they are moved to the non-driving axle, and for the used tires on the non-driving axle to cross over to the opposite side of the vehicle as they are placed onto the driving axle. For all-wheel drive (AWD) vehicles and four-wheel drive (4WD) vehicles, it is recommended that the used tires from each axle cross over as the fronts move to the rear and rears to the front. For the 4WD configuration, it is dependent upon how much 4WD driving is actually performed, whether it's controlled via mechanical/computerized devices or in vehicle controls, the recommendation will likely be found in the Owner/Operator manual or can be obtained by speaking to the manufacturer or dealership. Current thinking stresses the desirability of keeping the best used tires on the rear wheels of the vehicle, whether it is front, or rear wheel drive. The reason for this is that if the rear wheels lose grip before the front ones, an oversteer condition will occur, which is harder to control than the corresponding understeer which will happen if a front wheel is lost. This is also the case if a used tire blows out, so the intuitive belief that the front steering/driving tires need to be the best quality is not the case. A rear tire blowout will cause the vehicle to become very difficult to control, especially at highway speeds. It also greatly increases the risk of rollover due to yawing, a condition where the rear of the vehicle swings out and becomes perpendicular to the direction of travel. Yawing will cause the used tire to separate from the rim, the rim can then dig into the pavement, or dirt and grass if the vehicle is no longer on the road, which will trip the vehicle and cause a rollover. In some cases (for example, BMW), automobile manufacturers may recommend performing no used tire rotation at all. Additionally, some vehicles are designed (or retrofitted) with front and rear wheels of different sizes and unidirectional rotation treads, making rotation impossible. The front used tires on a front-wheel drive vehicle accelerate, steer, and help brake your vehicle. Front used tires tend to wear down faster than rear tires. Typically rear wheel used tires last twice as long as front wheel used tires. Ideally, we recommend you replace all four tires at the same time. Rotating your tires helps ensure even wearing for all your tires. Contact our staff to get your tires rotated. How do I know when to rotate my used tires? Follow your vehicle's owner's manual suggestions, rotate them with every other oil change, or rotate them every 3,000 to 7,000 miles. Service Type Most used tire sizes begin with a letter or letters that identify the type of vehicle and/or type of service for which they were designed. The common indicators are as follows: P225/50R16 91S P = When a used size begins with a "P," it signifies the tire is a "P-metric" size that was designed to be fitted on vehicles that are primarily used as passenger vehicles. This includes cars, minivans, sport utility vehicles and light duty pickup trucks (typically 1/4- and 1/2-ton load capacity). The use of P-metric sizes began in the late 1970s and they are the most frequently used type of used tire size today. 225/50R16 92S If there isn't a letter preceding the three-digit numeric portion of a used tire size, it signifies the used tire is a "Metric" size (also called "Euro-metric" because these sizes originated in Europe). While Metric used tire sizes are primarily used on European cars, they are also used on vans and sport utility vehicles. Euro-metric sizes are dimensionally equivalent to P-metric sizes, but typically differ subtly in load carrying capabilities. T125/90D16 98M T = If a used tire size begins with a "T," it signifies the tire is a "Temporary Spare" ("space saver" or "mini spare") that was designed to be used temporarily only until a flat used tire can be repaired or replaced. LT245/75R16 108/104S LT = If a used tire size begins with "LT," it signifies the tire is a "Light Truck-metric" size that was designed to be used on vehicles that are capable of carrying heavy cargo or towing large trailers. This includes medium and heavy-duty (typically 3/4- and 1-ton load capacity) pickup trucks, sport utility vehicles and full-size vans. Tires branded with the "LT" designation are the "little brothers" of 18-wheel tractor-trailer used tires and are designed to provide substantial reserve capacity to accept the additional stresses of carrying heavy cargo. 7.50R16LT 112/107Q, 8.75R16.5LT 104/100Q or 31x10.50R15LT 109Q LT = If a used tire ends with "LT," it signifies the used tire is either an earlier "Numeric", "Wide Base" or "Flotation" Ligh 3t Truck size designed to be used on vehicles that are capable of carrying heavy cargo and towing trailers (Numeric sizes), use 16.5-inch diameter rims (Wide Base sizes) or are wider, oversized used tires designed to help the vehicle drive on top of loose dirt or sandy surfaces (Flotation sizes). This includes light, medium and heavy duty (typically 1/2-, 3/4 and 1-ton load capacity) pickup trucks and sport utility vehicles. used Tires branded with the "LT" at the end of their size designation are also the "little brothers" of 18-wheel tractor-trailer used tires and are designed to provide substantial reserve capacity to accept the additional stresses of carrying heavy cargo. 195/70R15C 104/102R C = If a Euro-metric sized used tire ends with a "C," it signifies the used tire is a "Commercial" tire intended to be used on vans or delivery trucks that are capable of carrying heavy loads. In addition to being branded with the "C" in their size, these used tires are also branded with their appropriate Service Description. ST225/75R15 ST = If a used tire size begins with "ST," it signifies the used tire is a "Special Trailer Service" size that was designed to only be used on boat, car or utility trailers. ST-sized used tires should never be used on cars, vans or light trucks. Section Width Following the letter(s) that identify the type of vehicle and/or type of service for which the used tire was designed, the three-digit numeric portion identifies the tire's "Section Width" (cross section) in millimeters. P225/50R16 91S The 225 indicates this used tire is 225 millimeters across from the widest point of its outer sidewall to the widest point of its inner sidewall when mounted and measured on a specified width wheel. This measurement is also referred to as the used tire's section width. Because many people think of measurements in inches, the 225mm can be converted to inches by dividing the section width in millimeters by 25.4 (the number of millimeters per inch). 225mm / 25.4 = 8.86" Sidewall Aspect Ratio Typically following the three digits identifying the used tire's Section Width in millimeters is a two-digit number that identifies the used tire's profile or aspect ratio. P225/50R16 91S The 50 indicates that this used tire size's sidewall height (from rim to tread) is 50% of its section width. The measurement is the used tire's section height, and also referred to as the used tire's series, profile or aspect ratio. The higher the number, the taller the sidewall; the lower the number, the lower the sidewall. We know that this tire size's section width is 225mm and that its section height is 50% of 225mm. By converting the 225mm to inches (225 / 25.4 = 8.86") and multiplying it by 50% (.50) we confirm that this used tire size results in a tire section height of 4.43". If this used tire were a P225/70R16 size, our calculation would confirm that the size would result in a section height of 6.20", approximately a 1.8-inch taller sidewall. Internal Construction A letter (R in this case) that identifies the used tire's internal construction follows the two digits used to identify the aspect ratio. P225/50R16, P225/50ZR16 The R in the P225/50R16 91S size identifies that the used tire has a Radial construction in which the used tire's body plies "radiate" out from the imaginary center of the wheel. Radial used tires are by far the most popular type of used tire today representing over 98% of all used tires sold. If the R in the size was replaced with a D (225/50D16), it would identify that the internal used tire body plies crisscross on a Diagonal and that the used tire has a "bias ply" construction. Tires using this construction are for light truck and spare used tire applications. If the R in the size was replaced with a B (225/50B16), it would identify that the tire body plies not only crisscross the tire on a diagonal as before, but that they are reinforced with belts under the tread area. This type of used tire construction is called "Belted." used Tires using this construction are practically extinct. The European Tyre and Rim Technical Organisation (ETRTO) has adopted branding standards that allowed used tire manufacturers to identify used tires with self-supporting run-flat constructions within the used tire size designation. Self-supporting run-flat used tires may be identified with the letter F immediately following the traditional letter identifying used tire construction (such as the R designating radial) within the size. This results in size designations such as 225/45RF17 91Y (for self-supporting run-flat used tires that have a speed rating identified in their Service Description and 255/40ZRF20 (for Z-speed rated self-supporting run-flat used tires in which the speed rating is contained in the used tire size). Since this used tire size designation was adopted well after the introduction of self-supporting run-flat used tires into the marketplace, self-supporting run-flat used tires introduced and produced before it went into effect will not be required to be branded as such. Speed Rating Today, the only used tires that continue to include the speed rating "in" the used tire size (P225/50ZR16) are Z-speed rated tires. In this case, following the two digits used to identify the aspect ratio are the letters ZR to identify the tire's speed rating (Z) and its internal construction (R). Since 1991, all other speed ratings are identified in the tire's Service Description (which will be covered shortly). Tire and Wheel Diameter P225/50R16 91 The 16 indicates the used tire and wheel diameter designed to be matched together. Tires that have a rim diameter expressed in inches (P225/50R16, as well as 8, 10, 12, 13, 14, 15, 17, 18, 19, 20, 22, 23, 24, 26 and 28) are called "inch rim" sizes, are the most common type of used used tire size and are used on most cars, minivans, vans, sport utility vehicles and light duty light trucks. While not as common, two additional "unique" types of used tire/wheel diameters are still in use today. Tires and wheels that have a rim diameter expressed in "half" inches (8.00R16.5LT, as well as, 14.5, 15.5, 17.5 and 19.5) are used on some heavy-duty trailers, heavy-duty light trucks and box vans. Tires and wheels that have a rim diameter expressed in millimeters (190/65R390, as well as, 365 and 415) are called millimetric sizes. Michelin initiated millimetric sizes for their TRX used tires that saw limited use on many different car models in the late 1970s and 1980s. Michelin PAX System run-flat used tires have been introduced as an integrated wheel/ used tire system on a very limited basis as Original Equipment (O.E.) in North America. An example PAX System size of 235/710R460A 104T expresses used tire and wheel dimensions in millimeters (235 mm Section Width, used tire Overall Diameter of 710 mm and a 460A mm rim diameter, with the "A" in 460A signifying these used tires feature "asymmetric" beads in which the outside bead (450 mm) and inside bead (470 mm) are actually different diameters. All of these "unique" used tire/wheel diameters were developed specifically because the used tire and wheel design or intended vehicle use required them to be different than conventional tires and wheels. All of these tires and wheels feature bead profiles that have a different shape than traditional "inch rim" sizes. Tires and wheels with unique rim diameters should never be combined with traditional "inch rim" used tires and wheels. It is critical that the used tire and wheel diameters are always confirmed to match before the used tire is mounted on the wheel. Service Description P225/50R16 91S The 91S represents the tire's Service Description. A Service Description identifies the used tire's Load Index and Speed Rating. Service Descriptions are required on all speed rated (except for Z-speed rated) used tires manufactured since 1991. For more information on Service Descriptions, click here. Sidewall Markings In addition to the used tire's brand and line names (used tire model), there is a lot of information provided by the manufacturer on the sidewalls of the used tires they produce. Some of the branded information provides the used tire's basic dimensions and identifies the week it was produced. Other branding lists the types of materials used internally to reinforce the rubber, along with the used tire's maximum inflation pressures and loads. And others confirm the manufacturer certifies the used tire meets various industry standards and measures up to the government regulations of the nations in which it will be used. While not all information is branded on every used tire, the illustration includes the typical information found on many used tires. Rolling your mouse over any of the descriptions will highlight the appropriate branding on the used tire sidewall illustration. If you've ever been late for a date, appointment, or meeting because of a flat used tire, you already know how frustrating it can be. If you've ever changed a flat used tire in the rain, after dark, or on the shoulder of a busy highway, you already know how frightening it can be. So while we enjoy the freedom our vehicles provide, it's amazing how quickly that freedom vanishes when a flat used tire strands us. Since the early development of the automobile, used tires have played an important role in determining a vehicle's overall comfort and safety. However, there are few consumer products placed in harms way more often than our used tires, which encounter extremes in temperature, exposure to the elements, and attacks by debris on the road during their life. And while the used tire manufacturers' continuous research and development efforts have improved tire durability and longevity, only recently have they developed used tires that can temporarily maintain vehicle mobility using standard Original Equipment and aftermarket wheels. These run-flat used tires provide the driver more flexibility when deciding where to have used tire repairs made. Tires don't typically carry the weight of our vehicles, the air inside them does. There are three basic elements which determine the load capacity of a used tire: the size of the air chamber formed between the used tire and wheel, the strength provided by the used tire's construction to hold air pressure, and the amount of air pressure actually in the used tire. Most flat used tires (and used tire "blowouts") are the result of slow leaks that go unnoticed and allow the used tire's air pressure to escape over time. Therefore, monitoring tire air pressure in real-time gets us half way there. If we had tires that could maintain temporary vehicle mobility even after air loss, we'd be just about invincible. Today there are three technologies used as Original Equipment on vehicles to help maintain vehicle mobility when a used tire is punctured. They are self-sealing used tires, self-supporting used tires and used tires supported by an auxiliary system. Self-Sealing Self-sealing used tires are designed to fix most tread-area punctures instantly and permanently. These used tires feature standard used tire construction with the exception of an extra lining inside the used tire under the tread area that's coated with a puncture sealant that can permanently seal most punctures from nails, bolts or screws up to 3/16 of an inch in diameter. These used tires first provide a seal around the object when the used tire is punctured and then fill in the hole in the tread when the object is removed. Because these tires are designed to seal the used tire immediately upon being punctured, most drivers will never even know that they just had a puncture. Also because these used tires feature standard used tire constructions, the traditional loss-of-air symptoms that accompany a flat used tire remain to warn the driver if the tire is damaged beyond repair. Therefore, self-sealing used tires do not require a low air pressure warning system. DOT code: All DOT code: All used tires for use in the USA have the DOT code, as required by the Department of Transportation (DOT). It specifies the company, factory, mold, batch, and date of production (two digits for week of the year plus two digits for year; or two digits for week of the year plus one digit for year for used tires made prior to 2000). Although not law, some used tire manufacturers do not Tire manufactured suggest using a "new" tire that has been sitting on the shelf for more than six years (Ford Motor Company) or 10 years (Cooper Tire citing a used tire association recommendation).[15] JATMA, the Japanese Automotive Tyre Manufacturers Association recommends that all used tires be inspected at five years, and all used tires that were manufactured more than ten years previous be replaced.DOT code: All used tires for use in the USA have the DOT code, as required by the Department of Transportation (DOT). It specifies the company, factory, mold, batch, and date of production (two digits for week of the year plus two digits for year; or two digits for week of the year plus one digit for year for tires made prior to 2000). Although not law, some used tire manufacturers do not Used Snow tires are used tires designed for use in colder weather, snow and ice. Snow chains can be a slower-speed, temporary alternative in snowy conditions. Used Snow tires have more sipes than used summer tires, increasing traction on snow and ice, but reducing grip on dry and wet roads.Used Tires designed for winter conditions are optimized to drive at temperatures below 7 °C (45 °F)
