2. Tire code - Wikipedia

   en.wikipedia.org/wiki/Tire_code

   The load index on a passenger-car tire is a numerical code stipulating the maximum load (mass, or weight) each tire can carry. For load range "B" tires, ETRTO (ISO-Metric) standards specify the load index rating at an inflation pressure of 36 psi (250 kPa) (table below), while P-Metric standards measure the load capacity at an inflation ...

   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. The UTQG was created by the National Highway Traffic Safety Administration in ...

5. Tire uniformity - Wikipedia

   en.wikipedia.org/wiki/Tire_uniformity

   Tire uniformity. 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 ...

6. Slip (vehicle dynamics) - Wikipedia

   en.wikipedia.org/wiki/Slip_(vehicle_dynamics)

   In (automotive) vehicle dynamics, slip is the relative motion between a tire and the road surface it is moving on. This slip can be generated either by the tire's rotational speed being greater or less than the free-rolling speed (usually described as percent slip), or by the tire's plane of rotation being at an angle to its direction of motion (referred to as slip angle).

7. Tyre label - Wikipedia

   Tyre label. The Tyre Label is a mark for motor vehicle tyres. Manufacturers of tyres for cars, light and heavy trucks must specify fuel consumption, wet grip and noise classification of every tyre sold in EU market starting in November 2012. [1]
