Hey guys, a buddy and I were talking the other day about some rims I just ordered with tires. They're 20's with a 20mm offset of front and 25mm outback. The question I have is why are my tires different heights. My fronts are 245/35/20 and my rear are 275/30/20, why wouldn't I be able to run 35's all the way around or even 30's or is this just recommended for our cars? Ant input and advice would be greatly appreciated! Thanks in advance!
