I have some Gila Spider wheels that are 20 x 9 (f) and 20 x 10.5 with an off set of 40. I was wondering if I can run 245/35/20 in the front and 275/35/20 in the rear.

 

The reason that I am asking on the tires is because I found some really cheap

 

About the tyres: You can run 245/35/20 in front and 275/30/20 (not 275/35/20) in rear, but it depends on the offsets of the wheels and the fact is your car lowered (and how much) or not. With some specs it may rub, difficult to say beforehand.

About the wheels: Offsets are way too high for a rear wheel drive E60. Of course if you have the X model, then they might work.
