I have 335i with 403s 8 spd automatic and for the past 2600 miles my mpg has been 22, i will check my pressure today, I would liketo see what MPG other members are getting and what tire pressure are you running, I am also running on a staggered set up with all seasons bridgestones 19"

City driving or combo?
That's low... With snow tires on, I was getting 26 with stock Psi I flat on guide. I decided to go 38 f and 40 r and now getting 28 mostly highway.

Driving 18 396 style rims on 225/45 snows.

seems about right on the 22mpg. i have the same rims, 6spd manual and getting around the same. the difference in rim size do make a difference in mpg.

I have a 335i sport trim with 18" wheels.
Tire pressure is 34psi (front) and 38psi (rear).
99% of my driving is in the city and I average 17 mpg. (I always drive in COMFORT mode and very rarely in SPORT)
