Damage to tyres and rims is often not readily visible. Any unusual vibrations or signs that the car is pulling to one side may indicate that one of the tyres is damaged .

Tyre wear
Tyre wear is affected by several factors. These include:
Driving style – fast cornering, heavy acceleration and hard braking all increase tyre wear. The running gear should be checked by a qualified workshop if the tyres show excessive wear despite a normal driving style.
Unbalanced wheels – the wheels on new vehicles are balanced. However, various factors encountered in normal driving can cause them to become unbalanced, which results in steering vibration. Unbalanced wheels will affect levels of wear on the steering system and the suspension. In this case the wheels should be balanced again. New tyres have to be balanced after fitting.
Running gear setting – incorrect wheel alignment causes excessive tyre wear, impairing the safety of the vehicle. The wheel alignment should be checked by a qualified workshop if tyres show excessive wear.
