Your tyres are your only contact with the road – with a contact surface that is scarcely bigger than 4 footprints. Find out more about the right wheels and tyres for your model here.
Even if your thread depth is only 4 mm worn, your tyre has much less adhesion on a wet road. Reason: the tyre tread is no longer dissipating water optimally. We therefore recommend 3 mm for summer tyres and 4 mm for winter tyres. Is your tyre tread shallower? Don't take a risk – have new tyres fitted.
In most European countries, there is a minimum tread depth of 1.6 mm. We recommend a tread depth of 3 mm for summer tyres and 4 mm for winter tyres. The deeper the tread of your tyres, the more effective they are at draining off water and protecting you from aquaplaning.
