Tread depth
Warning! A reduction in tread depth leads to increased breaking distances.

A reduction in tread depth leads to an greater risk of aquaplaning and increased breaking distances. The tread wear indicator (TWI) on your tyre indicates when the tread depth has reached only 1.6 mm, which is the minimum legally permitted depth. This value has been reached once the tyre has worn down to the level of the indicators.

The sidewall inscription

You could be faced with legal consequences if your tyres fall below the legal minimum tread depth of 1.6 mm and, in some cases, it could even invalidate your insurance cover.

We recommend that summer tyres are changed when they reach a tread depth of 2 mm and winter tyres at 4 mm.

Ideally, you should check the tread depth on your tyres every four weeks using a special tread depth gauge (available from garages or specialist dealers). Winter tyres can also be checked very easily using a 1 euro coin. If the golden rim on the coin is just covered or if it is visible, this means that the remaining tread depth has fallen below 4mm.
