Tire age

Tire age  - Introduction - General information - Wheels and tires - Volvo S60 Owners Manual - Volvo S60

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. The temporary spare1 should also be replaced at 6-year intervals, even if it has never been used.

A tire's age can be determined by the DOT stamp on the sidewall (see the illustration).

A tire with e.g., visible cracks or discoloration should be replaced immediately.

Improving tire economy

  • Maintain correct tire pressure. See the tire inflation table on page 275.
  • 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.
  • Tires must maintain the same direction of rotation throughout their lifetime.
  • When replacing tires, the tires with the most tread should be mounted on the rear wheels to reduce the chance of oversteer during hard braking.
  • Hitting curbs or potholes can damage the tires and/or wheels permanently.
