I run 38 psi (cold tyre measurements) on all four wheels (19" rims). Also run 38 psi on all four wheels on the Cooper S. Both cars are fitted with run-flats.

With those pressures I have not noticed any harshness in ride in Comfort Mode, and even in Sport Mode the ride is firm but still smooth.

Current
38 Front 41 Rear

On my X1 with 19" wheels, it states the front pressure should be 37psi and the rear tyre 41psi.
Strangely, they are different size tyres - as fitted by BMW!
225/40 for the front and 255/35 for the rear.

I have 19" Goodyear tyres on my F31 M-Sport. Dealer said 40-42PSI. He also mentioned slightly higher on the rear.

36 front , 38 rear on my potenza rft

knightsabers · 12-04-2014, 06:22 AM

Front & Rear 38 PSI - 20' Pirelli P-Zero.

Hi All,

Just got my new car (demo) 2 weeks ago, I have the M sport pack with the 19s, and have read this thread and tried the tyre pressure of 38psi at the front and 40psi at the back (cold).

Normally have 3 passenger in the car (1 front and 2 back). Feel quite comfortable at these pressures, and I had used to have 40psi all around in my old A4 (not staggered and they are non RFTs).

Should I go 40psi at the front? I don't want it to be too bumpy.. Any advice will be appreciated!

Cheers
Ed

I'm running 35 front and 37 rear with bridgestone RE050a RFT and 19inch m-sport wheels.

With 2 psi different between front and rear feels better when cornering, the front feels more planted.

For BMW supplied tyres, try the Tyre Pressure placard on the driver's door post. It will list the recommended pressures for different tyres.

Thanks SilverZ. For 35 front and 37 back, does it give you good tyre life? I have the stock BS Pont s01

Thanks Bcoz - I have read the door's label, and it seems to suggest a much lower pressure. Even lower than when I got my car from the dealer.

Yeah the factory will always recommend less PSI for a more comfortable and supple ride. Ideally you will want 36PSI front and 38PSI rear. If you are carrying a bit more load then bump them both up by 2 psi.

I just picked my 2015 328i up and from new pressures were set at ~38 front and ~45 rear

etclam · 07-16-2015, 05:36 AM

Congrats Motlking! What wheel and tyre size have you got on yours? Also did you checked the pressure while hot? Or this was what the dealer told you?

That seems far too high on both front and rear.

Thanks mate! These are on the standard 19" M-Sports wheels.

I have tire pressure monitor so can view the tire pressure on the fly...

Don't take any notice what the tyre pressures are when you pick up a new car as when I checked mine cold the morning after taking delivery every tyre was different ranging from 32psi FR to 40psi LR. I let the dealer know quick smart. Not happy!

feng · 07-24-2015, 03:11 AM

Just got mine from my dealer after the 15k service and they deliberately put the pressure at 36/38.

That's the perfect pressure to have in my opinion

I run the same PSI in my 2er

GAV-F30 · 08-03-2015, 03:04 AM

I'm running them at 34psi all round, Tyres are KUMHO PS91 super sticky tyre.

Vinboyblue · 06-13-2018, 04:07 PM

I have 20 inch perelli runflats, 255/30/20. the dealer had them at 50psi. Not sure this is correct.

Ikester19 · 06-14-2018, 05:10 AM

On my F30 19” RFT’s I run 37 and 39.
