Tire Tread Depth: Minimum, Measurement & When to Change

Tread depth gauge: The most accurate method – a small measuring device that you press into the tread groove.
1-Euro coin: The gold rim is about 3 mm wide. If it disappears into the groove, you still have at least about 3 mm of tread – a practical benchmark for summer tires.
20-cent coin: Can be used as a rough guide for the winter recommendation.
Wear indicators (TWI): Small bars are located in the main grooves. If they are level with the tread, the legal limit of 1.6 mm has been reached. You can recognize their position by the "TWI" marking on the tire sidewall.
