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.
Remove the valve cap from the tire and press the air pressure gauge firmly onto the valve.
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.
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.
- Only use plastic valve caps or original Polestar valve caps.
Visually inspect the tire to make sure there are no nails or other embedded objects that could puncture the tire and cause air leakage.
Check the sidewalls to make sure there are no gouges, cuts, bulges or other irregularities.
Repeat this for all tires.
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.
