Hey everyone, I just bought new staggard 20s for my 03 X5 4.4. It had style 87 20s on it but were not staggard. I had 295 35 20 toyo proxesII on it and they are in excellent shape. I want to use 2 of them for my fronts and buy 2 new toyo proxesII 315 40 20 for the rear. The only problem is that there is a 1/2 of an inch difference in height between the two. Is this going to be a problem. When you really look at it, it is actually just a 1/4 of an inch when mounted on the vehichle. Any help is appreciated.
