Smooth tyres are a threat to the lives of your passengers, other road users and yourself. But you know that! What you may not know is that the validity of your car insurance policy is threatened by smooth tyres.

If it can be proved that an accident occurred because of badly worn or maintained, smooth or nearly smooth tyres, your car insurer may reject your insurance claim for repair or replacement.

The minimum legal car tyre tread depth is 1 mm all over. Bear in mind that this is the minimum and may be insufficient to prevent accidents on slippery or sandy surfaces.

To make sure that smooth tyres are not a threat to life or your insurance policy, check your tyres' tread and pressure regularly.

In addition, change your tyres as often as needed and NEVER even consider buying grooved tyres (second-hand smooth types with grooves cut in them). Doing so is close to suicidal and virtually gaurantees that your insurance claim will be rejected.
