07 Wheels and tires General information Summer and winter tires • Contact a Volvo workshop if you are unsure about the tread depth. WARNING • Storing wheels and tires When storing complete wheels (tires mounted on rims), they should be suspended off the floor or placed on their sides on the floor. Tires not mounted on rims should be stored on their sides or standing upright, but should not be suspended. The wheel and tire sizes for your Volvo are specified to meet stringent stability and handling requirements. Unapproved wheel/tire size combinations can negatively affect your vehicle's stability and handling. Approved tire sizes are shown in the Tire inflation pressure tables, see page 181. Any damage caused by installation of unapproved wheel/tire size combinations will not be covered by your new vehicle warranty. Volvo assumes no responsibility for death, injury, or expenses that may result from such installations. • CAUTION G020325 The arrows shows the direction of rotation of the tire Tires should preferably be stored in a cool, dry, dark place, and should never be stored in close proximity to solvents, gasoline, oils, etc. • When switching between summer and winter tires, mark the tires to indicate where they were mounted on the car, e.g., LF = left front, RR = right rear Tire wear Tire rotation Tire wear is affected by a number of factors such as tire inflation, ambient temperature, driving style, etc. Your vehicle is driven mainly by the front tires, which will wear faster. If the tires are rotated, they should only be moved from front to back or vice versa. They should never be rotated left to right/right to left. However, tire rotation, done at the recommended intervals, is one way of helping to keep `` • Tires with tread designed to roll in only one direction are marked with an arrow on the sidewall. 07 • Incorrectly mounted tires impair the car's braking properties and ability to force aside rain, snow and slush. • The tires with the most tread should always be at the rear (to reduce the risk of skidding). 177
