Warranty manuel 2022 (for all porsches?) at page 13 specify 58 psi for storage. On the forum i see 8-10 psi over normal. In my old 986 i have always put 50 lb. Finally i inflated at 55 lb. In my 22 Bgts 4.0. What do youthi k? Thank.
55-58 PSI is great. That's what I target in my heated garage. Without heat, people should target 58.....because you are going to lose a few psi with VT=nRT
Interesting. I was reading the owners manual for my M4 and it said to deflate the tires by half for winter storage. Wonder why BMW and Porsche suggest different approaches. Edit. Nevermind. I see that this is for vehicles in storage vs tires in storage.

PV=nRT is the ideal gas law. Air is not an ideal gas so you need to include z, compressibility factor. Over the (relatively) small difference in temperature between winter and summer there isn’t much difference in air compressibility factor.
Increasing the tire pressure will minimize the likelihood of the tires developing flat spots. For storage more than a month I generally inflate the tires to a few psi less than the maximum pressure rating shown on the tire sidewall. Or you can do what is shown in the owners manual or any other pressure you feel is best.
Most tires have a maximum inflation pressure not to exceed 50 psi. This amount of pressure seems excessive. I inflated mine to close to 50 psi for storage (4 months), garage not heated, never had any issue. Pressure will drop over time, by April when I take the car out, it still register 46psi or so.
