General information
WARNING!
●
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 on
pages 160 and
161 .
●
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.
New tires
Remember that tires are perishable goods. As of 2000, the manufacturing week and year will be
indicated with 4 digits (e.g. 1502 means that the tire illustrated was manufactured during week 15 of
2002).
Tire age
Tires degrade over time, even when they are not being used. It is recommended that tires generally be
replaced after 6 years of normal service. Heat caused by hot climates, frequent high loading conditions
or Ultra Violet (U.V) exposure can accelerate the aging process.
You should replace the spare tire when you replace the other road tires due to the aging of the spare.
A tire's age can be determined by the DOT stamp on the sidewall (see the illustration above).
A tire with e.g., visible cracks or discoloration should be replaced immediately.
Improving tire economy:
●
Maintain correct tire pressure. See the tire pressure table on pages 160 and 161 .
●
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.
