Your Ride: 97 840Ci
correct tire size for 18" M parallel
hi, getting oem 18" x 8 and 18" x 9.5 M parallel rims for my 840Ci and was wondering what is the most common/recommended tire size for these factory OEM rims?
I run 235/45/R18 on mine in the rear but their 8.5 wide. Dont go too low profile or your ride quality will suffer. If your run a 265 width, id probably go with a 40-45 hieght ratio.
