Tire pressures, hot climate

limeypride · 10-07-2021, 12:41 PM

So I pulled the trigger on some Michelin Pilot Sport 4Ss to replace the Pirellis that came with the car (

) as well as increase tread width and reduce the sidewall:
-> 295/30/20 rear
-> 285/30/20 front

I may also have to reduce my front spacer size to avoid rubbing but I'll deal with that if and when it happens.

Has anyone else done this in a hot climate (I'm in central FL)? I'm looking to see what tire pressures you went for at ambient temp. For the 35s, BMW recommend 34 psi I believe but with the reduced sidewall, that usually gets bumped up a bit hence the question.

Thx.

Hey Limey, quick question, where did you order the tires from. All the shops in Miami told me that the 295's are on back order. I currently have the PS 4S 285/35/20 but buying a new 21" wheel set and want to stick with same brand. Sorry I'm new to this and can't answer your question.
Thanks
