Audi A1 General maintenance Wheels and tyres Wheels
The tread wear indicators show the condition of the tyre treads.
The original tyres on your Audi A1 have 1.6 mm high "tread wear indicators" Fig. 1 running across the tread. Depending on the make, there will be 6 to 8 of them spaced at equal distances around the tyre. Markings on the tyre sidewall (for instance the letters "TWI" or a triangle) indicate the positions of the tread wear indicators.
The minimum tread depth required by law in Germany is 1.6 mm (measured in the tread grooves next to the tread wear indicators). Different figures may apply in other countries.
To avoid putting safety at risk, the tyres must be replaced at the latest when the tread is worn down to the tread wear indicators.
- Especially in difficult driving conditions such as wet or icy roads, it is important that the tyres have sufficient tread depth. The tread depth should be the same on the tyres of both the front and the rear axles.
- The decrease in driving safety due to insufficient tread depth is particularly evident in Audi A1 handling, when there is a risk of aquaplaning in deep puddles of water and when driving through corners. Braking is also adversely affected.
- The speed has to be adapted accordingly, otherwise there is a risk of losing control over the Audi A1.
