I'm reviving this old thread.
I was running a set of 255/35/18's in the rear but those were shredded so I went with 255/40/18 in the rear and now I'm rubbing a little more than I expected but nothing too major. The only reason I went with the 255/40/18 is because thats what came on my car when I bought it. Then I switched to the 255/35's so I figured going back to 255/40 wouldn't be an issue. The fronts are 235/40/18 with 18x8.5 et34 BBS CK's on all 4 corners.
I planned on rolling my fenders anyways so I could lower the car a little more so now I'm curious if running a 255/40 in the rear will be an issue. I'm also curious if running these tires will throw off my speedo at all.
Thanks in advance!
