Wear indicator
The tires have a so-called "wear indicator" in the form of a number of narrow strips running across or parallel to the tread. When approx. 1/16" (1.6 mm) is left on the tread, these strips show up 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.
To improve tire economy:
• Maintain correct tire pressure.
• Drive smoothly: avoid fast starts, hard braking and tire screeching.
• Tire wear increases with speed.
• Correct front wheel alignment is very important.
• Unbalanced wheels impair tire economy and driving comfort.
• If the wheels are rotated, they should be kept on the same side of the car so that they revolve in the same direction as prior to rotation.
• Hitting curbs or potholes can damage the tires and/or wheels permanently.
Flat spots
All tires become warm during use. After cooling, when the vehicle is parked, the tires have a tendency to distort slightly, forming flat spots. These flat spots can cause vibrations similar to the vibrations caused by
unbalanced wheels. They do, however, disappear when the tire warms up. The degree to which the flat spots form depends on the type of cord used in the tire. Remember that, in cold weather, it takes longer for the tire to
warm up and consequently longer for the flat spot to disappear.
CAUTION: The car must not be driven with wheels of different dimensions. The use of different size wheels can seriously damage your car's transmission. *
* This also applies to models equipped with All Wheel Drive (AWD).

Snow chains
Snow tire chains can be used on your Volvo with the following restrictions:
• Snow chains should be installed on front wheels only (this applies to cars with front wheel drive and to cars equipped with All Wheel Drive) . Use only Volvo approved snow chains.
• Snow chains may be mounted on tire dimension 185/65R15 and 195/60R15. Tire dimension 205/55R15 and 205/50R16 require a special type of snow chain. Consult your Volvo retailer. Snow chains may not be used on
205/55R16 tires. *
