I have a E46 (2001 325Ci) and am interested in wheels that are 18 x 8.5 and have a 35mm offset. It has been recommended that I use a 235/40/18 tire all around. There are some tires available that are 225/40/18 for the front and 255/35/18 for the rears. Will that work w/o modifications on my car, or should I stick with the 235/40 recommendation???? Help please!!!
