Bar grip tyres were developed in the 1930s and were the standard military pattern throughout World War II, for vehicles from Jeeps to heavy trucks and armoured cars. [1] They fell from favour in the 1970s and largely disappeared by the 1990s, having been replaced by newer patterns with better all-around performance.
Some car manufacturers recommend against performing tire rotation, for example BMW. [4] Many tire manufacturers say that tire rotation is no longer necessary, except to ensure that best tires are fitted at the rear of the vehicle. [5] In practice this means that when the front tires become worn, the new ones should be fitted to the rear, moving ...

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).
Once the force exceeds the limit circle, that tire starts to slip. Skidding is the vehicle's response to one or more tires slipping. The vehicle dynamics during a skid will depend on whether some or all of the tires are skidding, and whether the car was rotating or turning when the skid began.
Rotating spinner wheel The modern spinner device is a decorative kinetic attachment to the wheel of an automobile. [ 19 ] The spinner covers the center of a car's wheel and is designed to independently rotate by using one or more roller bearings to isolate the spinner from the wheel, enabling it to turn while the wheel is at rest.
A tubeless tire (also spelled as tubeless tyre in Commonwealth English) is a pneumatic tire that does not require a separate inner tube.. Unlike pneumatic tires which use a separate inner tube, tubeless tires have continuous ribs molded integrally into the bead of the tire that are forced by air pressure into a flange on the metal rim of the wheel, sealing the tire to the rim.
Airless tires, non-pneumatic tires (NPT), or flat-free tires are tires that are not supported by air pressure. [1] [2] [3] They can be used on small vehicles such as ride-on lawn mowers and motorized golf carts. They also are used on heavy equipment required to operate on sites where risk of tire punctures is high.
