17 inch tire pressure?

Mikee82 · 11-26-2016, 01:50 PM

Changed down to 17 inch rims for winter tires from the MSport 19 inch package on my 2014 X3 Msport 28I. Door jam lists only 18" inch wheel size for inflation pressures of 32/35. What are people running 17" run flat pressures at? Tire size is 225/60/17. Tire shop went 35lbs all four corners.

I also use 17" winter tires and rims. I set them to 34/37 respectively since the cold temperature will lower the air pressure when stationary.

I run about 36psi all around - 245/50/17 Pirelli Sottozeros

Just checked the manual, should of just looked there first... Manual indicates 32/35, I'll drop a few lbs in the front.

I tend to keep the front/rear pressure ratio the same regardless. i.e.. door says 32-38 so ill always make sure the rear has +6 psi over the front thats what feels best to me.
