Adjusting tyre pressure

Tyre pressure decreases over time, this is a natural phenomenon. The tyre pressure must therefore sometimes be adjusted in order to maintain the recommended tyre pressure.

Use the recommended tyre pressure for cold tyres in order to maintain good tyre performance and even tread wear.


To avoid incorrect tyre pressure, the pressure should be checked on cold tyres. "Cold tyres" means the tyres are the same temperature as the ambient temperature (approx. 3 hours after the car has been driven). After a few kilometres of driving, the tyres warm up and the pressure increases.
Remove the cap from the valve on one tyre and then press the tyre pressure gauge firmly down onto the valve.
Inflate the tyres to the correct pressure, see the decal on the door pillar on the driver's side showing the recommended pressure for factory fitted tyres.
Refit the dust cap.


  • After a tyre has been inflated, always refit the dust cap in order to avoid damage to the valve from gravel, dirt, etc.
  • Use only plastic dust caps or genuine Polestar dust caps.
Check the tyres visually for any implanted nails or other objects that could puncture the tyre and cause leakage.
Check the sidewalls for any cavities, cuts, bumps or other irregularities.
Repeat this for all tyres.


If you have over-inflated, release air by pressing in the metal pin in the centre of the valve. Then check the pressure again using the tyre pressure gauge.

Some spare wheels require a higher tyre pressure than other tyres. Check in the tyre pressure table or on the tyre pressure label.
