Hysteresis effect in race car tire and street car tire.

Tires are made from rubber, which is a viscoelastic material the loading and unloading stiffness curve are not exactly the same thus which make a loop with the unloading curve below the loading. The area within the loop is the amount of dissipated energy during loading and unloading. We are called hysteresis loop or damping properties .As a tire rotates under the weight and carry load of a vehicle, it experiences repeated cycles of deformation and recovery and it dissipates energy loss as heat. The amount of dissipated energy depends on the mechanical characteristics of the tire. Hysteresis energy loss in rubber decreases as temperature increases. The hysteresis effect causes a loaded rubber not to rebound fully after load removal.
Consider a high hysteresis race car tire rolling over road irregularities. The deformation tire recovers slowly and therefore, it cannot push the footprint tail on the road as hard as the footprint head. The difference in tail and head pressure causes a resistance force, which is called rolling resistance. Race car have high hysteresis tire to increases friction and limited traction that improve stability during running match. Street car such as passenger car  truck tire and solid tire have a low hysteresis tire to reduce the rolling resistance and low operating temperature that improve fuel consumption.  Hysteresis level of tire inversely effect the stopping distance such as a high hysteresis tire make the stopping shorter however it wear rapidly and has a shorter life time but do not affect with race car .
