2. Tire rotation - Wikipedia

   en.wikipedia.org/wiki/Tire_rotation

   [citation needed] 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 tires, unless they are remounted. 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 ...

3. Bar grip - Wikipedia

   en.wikipedia.org/wiki/Bar_grip

   Bar grip tyres, or 'NDT' (Non-Directional Tire) in US military parlance, are an early tyre tread pattern developed for off-road use. Bar grips are characterised by a solid rubber circumferential centre strip, with large solid cleat alternately to either side. These span the full width of the tread.

4. Mecanum wheel - Wikipedia

   en.wikipedia.org/wiki/Mecanum_wheel

   These rollers typically each have an axis of rotation at 45° to the wheel plane and at 45° to the axle line. [3] Each Mecanum wheel is an independent non-steering drive wheel with its own powertrain , and when spinning generates a propelling force perpendicular to the roller axle, which can be vectored into a longitudinal and a transverse ...

5. Omni wheel - Wikipedia

   en.wikipedia.org/wiki/Omni_wheel

   The free rotating rollers (dark gray) allow the wheel to slide laterally A molded plastic omni wheel. Omni wheels or poly wheels, similar to Mecanum wheels, are wheels with small discs (called rollers) around the circumference which are perpendicular to the turning direction. The effect is that the wheel can be driven with full force, but will ...

6. Radial tire - Wikipedia

   en.wikipedia.org/wiki/Radial_tire

   A cross-section of a tire. Number 12 indicates the radial ply. Numbers 14 and 16 are bias plies. A radial tire (more properly, a radial-ply tire) is a particular design of vehicular tire. In this design, the cord plies are arranged at 90 degrees to the direction of travel, or radially (from the center of the tire).

7. Wheelspin - Wikipedia

   en.wikipedia.org/wiki/Wheelspin

   Wheelspin can also occur when changing gears while the vehicle is in motion, as the inertia of the engine and flywheel rotating at a higher rate than the next highest gear tries to bring the input shaft of the transmission to the same speed. This is known commonly as lift-off oversteer.
