Tire tread wear indicators
There are tread wear indicators to show the status of the tire's tread depth.
The narrow grooves that run lengthwise across the tire's tread pattern are tread wear indicators. On the side of the tire are the letters TWI[1].
Important
- Tires should be changed before wearing them down to the tread wear indicators to avoid poor traction in rain and snow.
- Volvo recommends that winter tires have a greater tread depth than 3 millimeters (1/8 inch) and summer tires 1.6 millimeters (1/16 inch).
