Information area The location and pressure indicators on the sidewall information area improve safety. The information area allows for recording the correct inflation pressure and installation location during tire change. Safety is improved further by a new section that can be used to record the tightening torque of bolts for alloy rims. Most of the sporty UHP tires will be installed on aluminum rims that require special attention when tightening the bolts. It is important to tighten the bolts to the correct torque, and to retighten them after approx. 100 to 200 kilometres of driving.
