Tires – storage and age
When storing complete wheels (tires mounted on rims), they should be suspended off thefloor or placed on their sides on the floor.
New Tires
Remember that tires are perishable goods. Asof 2000, the manufacturing week and year(Department of Transportation (DOT) stamp)will be indicated with 4 digits (e.g., 1513means that the tire illustrated was manufac-tured during week 15 of 2013).
Tire ageTires degrade over time, even when they are not being used. It is recommended that tiresgenerally be replaced after 6 years of normalservice. Heat caused by hot climates, fre-quent high loading conditions or Ultra Violet(U.V.) exposure can accelerate the agingprocess. The temporary spare

should also
be replaced at 6-year intervals, even if it hasnever 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.
Storing wheels and tiresWhen storing completes wheels (tires moun-ted on rims), they should be suspended offthe floor or placed on their sides on the floor. Tires not mounted on rims should be stored on their sides or standing upright, but shouldnot be suspended.
CAUTION
Tires should preferably be stored in a cool, dry, dark place, and should never bestored in close proximity to solvents, gaso-line, oils, etc.
WARNING
• The wheel and tire sizes for your Volvo are specified to meet stringent stabilityand handling requirements. Unap-proved wheel/tire size combinationscan negatively affect your vehicle'sstability and handling.
• Any damage caused by installation ofunapproved wheel/tire size combina-tions will not be covered by your newvehicle warranty. Volvo assumes noresponsibility for death, injury, orexpenses that may result from suchinstallations.

Self-supporting run flat tires (SST)
Self-supporting run flat tires are available as optional equipment on certain models. The vehicle must be equipped with one of the tire pressure monitoring systems if tires ofthis type are installed. Tires of this type have specially reinforced sidewalls that make it possible to continuedriving to a limited extent even though the tirehas lost some or all of its inflation pressure.These tires are mounted on special rims (nor-mal tires can also be mounted on these rims). If an SST tire loses inflation pressure, the yel- low TPMS symbol illuminates in the instru-ment panel and a text message is also dis-played. If this happens, reduce speed to notmore than 50 mph (80 km/h). The tire shouldbe replaced as soon as possible.WARNING
• SST tires should only be mounted by service technicians who are familiarwith tires of this type.
• SST tires may only be mounted onvehicles equipped with a tire pressuremonitoring system.
• Do not drive faster than 50 mph(80 km/h) if the monitoring system indi-cates that a tire has lost inflation pres-sure.
• Do not drive farther than 50 miles(80 km) before replacing a damagedSST tire.
• Drive carefully and avoid e.g., hardbraking or fast turns.
• SST tires must be replaced if they aredamaged. A tire of this type cannot berepaired.

Tire sealing system* – general information
Certain models are equipped with a tire sealing system
* that enables you to tempo-
rarily seal a hole in the tread surface and re-inflate a flat tire, or to adjust a tire’s inflationpressure.
IntroductionThe tire sealing system consists of an air compressor, a container for the sealing com-pound, wiring to connect the system to thevehicle’s electrical system via one of the 12-volt sockets, and a hose used to connect thesystem to the tire’s inflation valve.
NOTE
The tire sealing system's compressor has been tested and approved by Volvo.
