What PSI for Winter wheel package (on car delivered with Summer wheels)?

[jcfay]

Hi folks - since I received my vehicle with the OEM Summer 21s, I'd imagine the door pressure inflation info reflects that setup, correct? Should I use the same or different inflation pressures now for the OEM Winter 20s?

Thanks

I'm running the 491 winter package (staggered 20" wheels, 275/315). They came from the dealer at 41 psi and I lowered them to 38 all around. The door and manual say 36.

I'm running 38 all around on my OE winter set from BMW. Dealership said 36 psi was correct, but I felt it a bit soft, so I increased it a touch.

Well, I'm pleasantly surprised that no one hit me with the as it is in there. Duh. For the non-staggered 285/40 R20s, it shows 36 psi front 31 (!) rear, for > 100 mph, 42 for both. I thought the winter setup wasn't in the manual, but it was. thx again

Interesting we came to the same conclusion.

Well, since I somehow frequently end up over 100mph, not intentionally, of course, I'll stick with my 38 all around, as it seems to work well.
