yre technology has become extremely advanced. Tyres are not merely the point of contact between the car and the ground, they also have several important functions and characteristics including: steering, carrying a load, absorbing road shock, rolling smoothly, transmitting mechanical inputs and wearing evenly.

Common questions

Why is tyre maintenance so important?
Tyres are placed under a considerable amount of stress. Regular checks therefore ensure that tyre pressure is maintained and that the tread is not too worn or defective.

What happens if tyres are not replaced?
Tyres that are not regularly checked can become worn out or show defects, both of which can compromise safety. In addition, something as simple as incorrect tyre pressure can have an effect on fuel efficiency, road stability and short term tread wear.

How often should they be replaced?
Every tyre has a wear bar limit built into the tread which indicates how worn it is. The current minimum legal tread depth in the UK is 1.6 mm, measured across 75% of the central part of the tyre in unbroken bands. Most tyres will need replacement before 10 years of use, however it is recommended that all tyres – including spare tyres – be replaced every 10 years even if they appear to be in good condition.
