It is subjected to lateral loads when moving, etc. During this curve, the vehicle will move due to inertia. The vehicle attempts to move in a straight line, but the relationship between the steered tires and the road surface on which this vehicle is traveling It curves along the path that minimizes resistance due to the frictional force between the two. This frictional force is the shear load of the tire, especially the front tire, at its tread throat. This causes the tire to deform (shear deform) laterally toward the turning center. child The magnitude of the shear deformation, or frictional force, acting on the tire is supported by this tire. at least partially proportional to the load being carried. Acts on this vehicle when making curves. The centrifugal force exerted on the tires on the outside of this curve The inner tires experience greater shear forces than the inner tires.

On curves at low or medium speeds in daily driving, a normal tire will experience its shear deformation. The sidewall stiffness is sufficient to limit the No problems occur.However, in the case of high-speed curves in races, etc., this tire deformation causes serious problems. If this deformation directs this tire toward the center of the curve, If the tire's tread becomes so large that it cannot hold it, the contact area of the tire's tread will rapidly decrease. decreases to This reduction in the contact area causes the tire to break and cause slippage. and the controllability of the vehicle is impaired.
