Tire Rotation
Volvo recommends rotating the tires every 7,500 miles (12,000 km). Tires should be rotated front-to-
back/back-to-front only. Tires must maintain the same direction of rotation throughout their lifetime, and
should never be rotated from one side of the vehicle to the other.

Tire wear indicators

Tires have tread wear indicators

The tires have wear indicator strips running across or parallel to the tread. When approx. 1/16 inches
(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 have a very poor grip in rain or snow.
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.
