Checking tire pressure A certain amount of air seepage from the tires occurs naturally and tire pressure fluctuates with seasonal changes in temperature. Always check tire pressure regularly. Cold tires Inflation pressure should be checked when the tires are cold. 159 07 Wheels and tires Tire inflation The tires are considered to be cold when they have the same temperature as the surrounding (ambient) air. This temperature is normally reached after the vehicle has been parked for at least 3 hours. After driving a distance of approximately 1 mile (1.6 km), the tires are considered to be hot. If you have to drive farther than this distance to pump your tire(s), check and record the tire pressure first and add the appropriate air pressure when you get to the pump. If checking tire pressure when the tire is hot, never "bleed" or reduce air pressure. The tires are hot from driving and it is normal for pressures to increase above recommended cold pressures. A hot tire at or below recommended cold inflation pressure could be significantly under-inflated. To check inflation pressure: 1. Remove the cap from the valve on one tire, then firmly press the tire gauge onto the valve. 2. Add air to reach the recommended air pressure. 3. Replace the valve cap. 4. Repeat this procedure for each tire, including the spare. 5. Visually inspect the tires to make sure there are no nails or other objects embedded that could puncture the tire and cause an air leak. 6. Check the sidewalls to make sure there are no gouges, cuts, bulges or other irregularities. NOTE If you overfill 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 tables on pages 160 and 161, or see the inflation pressure placard. 160 07 Wheels and tires Tire inflation pressure table - U.S. models The following tire pressures are recommended by Volvo for your vehicle. Refer to the tire inflation placard for information specific to the tires installed on your vehicle at the factory.

Checking tire pressure
A certain amount of air seepage from the tires occurs naturally and tire pressure fluctuates with seasonal changes in
temperature. Always check tire pressure regularly.
Cold tires
Inflation pressure should be checked when the tires are cold.

Tire inflation
The tires are considered to be cold when they have the same temperature as the surrounding (ambient) air.
This temperature is normally reached after the vehicle has been parked for at least 3 hours.
After driving a distance of approximately 1 mile (1.6 km), the tires are considered to be hot. If you have to drive
farther than this distance to pump your tire(s), check and record the tire pressure first and add the appropriate air
pressure when you get to the pump.
If checking tire pressure when the tire is hot, never "bleed" or reduce air pressure. The tires are hot from driving and it
is normal for pressures to increase above recommended cold pressures. A hot tire at or below recommended cold
inflation pressure could be significantly under-inflated.
To check inflation pressure:
1. Remove the cap from the valve on one tire, then firmly press the tire gauge onto the valve.
2. Add air to reach the recommended air pressure.
3. Replace the valve cap.
4. Repeat this procedure for each tire, including the spare.
5. Visually inspect the tires to make sure there are no nails or other objects embedded that could puncture the tire and
cause an air leak.
6. Check the sidewalls to make sure there are no gouges, cuts, bulges or other irregularities.
NOTE
If you overfill 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 tables on
pages 160
and 161
, or see the inflation pressure placard.
