Proper PSI for 19'' wheels and PSS?

Mean E92 · 10-31-2016, 01:20 PM

I currently have 18''s with run flats and I run them at the same pressure that the doorjamb sticker says to. What should I run on my new setup?

Anyone? Please.

You use the same tire pressure as listed in the sticker in the door.

Even if the specs on the door are for 18's with smaller tires? I have 19's now and larger tires. I would the PSI would be different, no?

I'd say anywhere from 33-35 psi front and 37-40 rear. Depending on ride prefence

Not really. The recommended PSI is fine. Some people like higher PSI because they like the firmer ride. You can run whatever pressure you like as long as you stay somewhere between the BMW recommended and max PSI rating of the tire.

Look in the owner's manual. There's a huge list in mine. Is it not there?

I did look into the manual. There's no option for a 235/265 setup. At this time I'm running 36 PSI F/ 38 PSI R. It feels soft but this may be cause I'm so used to RFTs.

I agree with this.

My door jamb with 19" PSS on 225M wheels is like 38F 46R

This is what I run for my summer setup.

I think the car feels much better with higher pressure, I like 39f/46r on my as3s. I think with tires with a stiffer sidewall, even non rfts, I would use lower pressures
