adamr · 07-01-2008, 02:28 PM

Under normal use what tyre pressure are you guys using on your M3's for the rear and front?

those at altitude id like to hear your pressures used as well (as i am at altitude)

im using 2.4Bar at the front and 2.6Bar at the rear ... when i bought the car it was set at 2.5 all round !?

interesting...why? The reason I ask is because the doorsill sticker says 33 front and 35 rear. When I got the car and when she came back from break-in service it came back with 35 front and 37 rear. So I drained it when cold back down to 33/35. Periodically am over 100mph, but never for more than a few seconds. Why do you think the dealership put 2+ PSI in each corner like you're suggesting?

I put about +2 psi extra for added protection against potholes. Also especially since it's getting a bit chilly, and at night temperatures can drop like over 10 degrees if not more. I believe for every 10 degrees drop in temp, it's like 1psi drop in your tires.

So my reasons are very simple I just want a bit better protection against potholes especially since I live in nyc and the roads aren't so great.
