Do I need to change all four tyres on a quattro?
With four-wheel drive vehicles, you may need to replace all four tyres when one gets worn out or has a puncture. This is because 4×4 systems rely on all four tyres when operating. In the case of four wheel drive cars, you may have to change either both tyres on an axle, or even all four tyres at the same time, to avoid damaging the four wheel drive system (consult your car manufactures handbook for recommendations).
