Tread wear indicator

Tread wear indicator  - Tire wear - General information - Wheels and tires - Volvo S60 Owners Manual - Volvo S60

The tires have wear indicator strips running across or parallel to the tread.

The tires have wear indicator strips running across or parallel to the tread. The letters TWI are printed on the side of the tire. When approximately 1/16" (1.6 mm) is left on the tread, these strips become visible and indicate that the tire should be replaced. Tires with less than 1/16" (1.6 mm) tread offer very poor traction.

When replacing worn tires, it is recommended that the tire be identical in type (radial) and size as the one being replaced. Using a tire of the same make (manufacturer) will prevent alteration of the driving characteristics of the vehicle.
