Question

DentroTest · Accepted Answer

An inflation pressure higher than the recommended one causes the central part of the tire to bear almost all of the contact with the asphalt. As it bulges outward, the contact surface decreases, which reduces grip instead of increasing it. In addition, this problem causes uneven wear in the center of the tread, and not on the edges or sidewalls, which is typical of low pressures. As the tire loses flexibility, it does not properly absorb the irregularities of the road surface and transmits the jolts to the chassis, which promotes deterioration of the shock absorbers and the suspension components.
