Damage to tyres and rims is often not readily visible. If you notice unusual vibration or the car pulling to one side, this may indicate that one of the tyres is damaged .

Tyre wear
The tyre wear is affected by several factors:
Driving style – fast cornering, heavy acceleration and hard braking all increase tyre wear. Have the running gear checked by a qualified workshop if the tyres show excessive wear despite 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. A new tyre will have to be balanced after fitting.
Running gear settings – incorrect wheel alignment causes excessive tyre wear, impairing the safety of the vehicle. Have the wheel alignment checked by a qualified workshop if tyres show excessive wear.
