2. 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).

3. Tire rotation - Wikipedia

   en.wikipedia.org/wiki/Tire_rotation

   Car and tire manufacturers may recommend tire rotation frequency and pattern, typically every 5,000 mi (≈8,000 km) to 8,000 mi (≈13,000 km) depending on the tire manufacturer and vehicle make [3] to ensure even tire wear. A common rotation pattern is to move the back wheels to the front, and the front to the back but crossing them when ...

4. Radial force variation - Wikipedia

   en.wikipedia.org/wiki/Radial_force_variation

   Radial force variation or road force variation [1] (RFV) is a property of a tire that affects steering, traction, braking and load support.High values of RFV for a given tire reflect a high level of manufacturing variations in the tire structure that will impart ride disturbances into the vehicle in the vertical direction.

5. Tire balance - Wikipedia

   en.wikipedia.org/wiki/Tire_balance

   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.

6. Circle of forces - Wikipedia

   en.wikipedia.org/wiki/Circle_of_forces

   The vehicle to which the tire is attached is moving in the positive y direction. In this example, the vehicle would be cornering to the right (i.e. the positive x direction points to the center of the corner). Note that the plane of rotation of the tire is at an angle to the actual direction that the tire is moving (the positive y direction).

8. Tire uniformity - Wikipedia

   en.wikipedia.org/wiki/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 run-out , and ...

9. Lateral force variation - Wikipedia

   en.wikipedia.org/wiki/Lateral_Force_Variation

   Assume a perfectly uniform tire mounted on a perfectly round wheel loaded with a constant force against a perfectly round test wheel. As the wheel turns, it turns the tire, and the tire carcass undergoes repeated deformation and recovery as it enters and exits the contact area. If we measure the lateral force between the tire and the wheel we ...
