Wheels and tires Tire condition / tire pressure

Tires are safety-relevant items that are only capable of meeting the requirements imposed if they are run at the correct tire pressure and with sufficient tread depth.

The tire pressures indicated are minimum pressures. The tires must never be run at lower pressures since this affects roadholding adversely and may lead to severe tire damage.

Valve caps protect the valve against dust and dirt and therefore help prevent leaks. Always screw on caps tightly and replace missing caps.

For safety reasons, do not limit tire checks to checking the tire pressure but also check for sufficient tread depth, ingress of foreign matter, pinholes, cuts, tears and bulges in the sidewall (cord breakage)!

Tire pressure of cold tires (approx. 20'C) (summer and winter tires)

16 inch wheels front rear

2.5 bar pos. pressure 3.0 bar pos. pressure

17 inch wheels front rear

2.5 bar pos. pressure 2.5 bar pos. pressure

3,0 bar pos. pressure with 275/35 ZR 17 tires

Collapsible spare tire front/rear

2.5 bar pos. pressure

Tire and wheel survey / tire specification character

For a tire and wheel surview for summer and winter tires, refer to the relevant Technical Information (Tl), Group 4.

When replacing summer tires, check for the correct tire specification character. The specification characters N 2, N 1 or N 0, respectively, help to distinguish summer tires approved by Porsche from other versions of identical tire type and the same tire size. The tires approved by Porsche are also identified in the corresponding Tl.
