Hello. My 2004 escalade is sitting on a 305/50/20 tires. I bought this vehicle used and it came with that tires. My concern is the rear tires rubs on the inner fender. I just put a 1/4" wheel spacer today and I hope this will fix the problem. If not I might have to change the wheels since the wheel's chrome is peeling off. What is the right offset wheel if I want to keep the tires. I have 95% thread life with the tires. Any advice will be appreciated. Thanks in advance
