Useful Information About Tyres

Your tyre tread is vitally important to your safety on the road. In wet weather, the grooves of your tyres help to remove water from the contact patch between your tyres and the road surface, meaning your car can brake, steer and accelerate properly. Without adequate tread depth, your tyres may not be able to perform properly in wet conditions reducing your safety on the road.

On very wet roads, low tread depth could even result in you losing complete control of your vehicle through a hazardous process called "aquaplaning". Watch our video to find out more. By regularly checking your tread depth, you can minimise the risk, helping to keep you, your passengers and other roads users safe.

Tyre Tread Measurements:

MAXIMUM TYRE TREAD = 8mm

MINIMUM LEGAL LIMIT = 1.6mm

MAXIMUM USABLE TREAD = 6.4mm

Please Note: Tyres are health checked by taking three readings across the width of the tyre, starting with the outside tread depth measurement. Any excessive variance in the three readings may indicate the need for a wheel alignment check to avoid further excessive wear.

As a rough guide, a millimeter (1mm) of tyre tread lasts from approximately 1,000 - 4,000 miles dependent upon driving style, road and weather conditions and tyre rubber compound.

  • 8mm - Your tyre is 0% worn
  • 7mm - Your tyre is 15% worn
  • 6mm - Your tyre is 31% worn
  • 5mm - Your tyre is 47% worn
  • 4mm - Your tyre is 62% worn
  • 3mm - Your tyre is 78% worn
  • 2mm - Your tyre is 94% worn
  • 1.6mm - Your tyre is 100% worn
