Many drivers check the pressure of their vehicles’ tyres and scan the tyres for signs of damage, but few accurately check for tread depth using a tyre tread depth gauge. With Continental tyres, our built-in tyre tread wear indicators (TWIs) can save you time and money, while also making you safer.
TWIs are cross-ribs which are evenly spaced around the circumference of the tyre, along the main longitudinal tread grooves. They are positioned in the central three-quarters – or contact patch – of your tyres. These gauges become level with the tyre surface when the remaining tyre tread is down to approximately 1.6 mm. Continental recognises this measurement as the most widely accepted minimum at which car tyres should be removed from a vehicle.
This standard has been adopted as a legal minimum by many of the world’s national transportation authorities. Our TWIs are more efficient than, and just as accurate as, a tyre tread depth gauge. There is no better way to comply with UK Tyre Laws, and to keep you and your vehicle safe, than to make sure that you know your tyre tread depth by using Continental TWIs.
Continental recommends the following depths for tyre replacement:
In the interests of motorist safety, our recommendation for the wear limit of tyre tread depth is more than the 1.6 mm legal limit mentioned above. Continental recommends a depth limit of:
a minimum of 3 mm for summer tyres
a minimum of 4 mm for winter tyres
