Volvo XC90: Wheels and tires / Adjusting tire pressure

Tire pressure decreases over time, which is normal. The tire pressure must therefore be adjusted to maintain the recommended tire pressure.

Use the recommended inflation pressure for cold tires to help maintain good tire performance and even wear.

NOTE

To help prevent incorrect inflation pressure, pressure should be checked when the tires are cold. The tires are considered to be cold when they have reached the same temperature as the ambient temperature (about 3 hours after the vehicle was last driven). After driving for a few kilometers, the tires will warm up and the pressure will increase.

1. Remove the valve cap from the tire and press the air pressure gauge firmly onto the valve.
2. Inflate the tire to the correct inflation pressure; see the tire pressure placard on the driver's side B pillar for recommended pressures for factory-mounted tires.
3. Screw the valve cap back on.

   NOTE

   • After inflating a tire, always replace the valve cap to help prevent valve damage caused by gravel, dirt, etc.
   • Use plastic valve caps only. Metal caps could corrode and become difficult to remove.
4. Visually inspect the tire to make sure there are no nails or other embedded objects that could puncture the tire and cause air leakage.
5. Check the sidewalls to make sure there are no gouges, cuts, bulges or other irregularities.
6. Repeat this procedure for each tire, including the spare tire¹.

NOTE

If you have overfilled the tire, release air by pushing on the metal stem in the center of the valve. Then recheck the pressure with your tire gauge.

Some spare tires require higher inflation pressure than the other tires. Consult the tire inflation pressure table or the inflation pressure decal.
