The letters of the model code is found by combining the letters of the engine code with the platform code. If the engine code and the platform code have two letters each, the middle letter is computed according to this formula: [ 1 ] [ 2 ]
Light truck tires are indicated by the letters LT at the end instead of the beginning of the sequence, as follows: The tire diameter is given for High Flotation tires and omitted from Numeric tires. 2-digit number: The diameter of the tire in inches. x: Separator character. 3- or 4-digit number: The section width (cross-section) of the tire in ...
Tire uniformity refers to the dynamic mechanical properties of pneumatic tires as strictly defined by a set of measurement standards and test conditions accepted by global tire and car makers. These standards include the parameters of radial force variation , lateral force variation , conicity, ply steer, radial run-out , lateral run-out , and ...
The model codes fall into three periods, 1937 to late 1950s, late 1950s to late 1970s and late 1970s to present. There was some overlap as new models were phased in using new codes while old models were phased out using the old codes. The model code is not the same as the VIN.
UTQG ratings on sidewall of Toyo Tires Proxes R39 tire UTQG ratings (top) and tire code (bottom) on sidewall of Continental ContiProContact tire. Uniform Tire Quality Grading, commonly abbreviated as UTQG, is a set of standards for passenger car tires that measures a tire's treadwear, temperature resistance and traction.
VIN on a Chinese moped VIN on a 1996 Porsche 993 GT2 VIN visible in the windshield VIN recorded on a Chinese vehicle licence. A vehicle identification number (VIN; also called a chassis number or frame number) is a unique code, including a serial number, used by the automotive industry to identify individual motor vehicles, towed vehicles, motorcycles, scooters and mopeds, as defined by the ...
The slipping velocity (difference between the velocity of the car and the velocity of the tire in the contact point) will change very quickly and the model becomes a stiff system (a system whose eigenvalues differ a lot), which may require a special solver. The general form of the Magic Formula, given by Pacejka, is: [8]
Tires with large unbalances are downgraded or rejected. When 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 their combined unbalance. Tires may be rebalanced if driver perceives excessive vibration. Tire balancing is distinct from wheel alignment.
