I've tried to mount 3 different steelies in the 4-4.25 range & got no love... I know Rock Crawlers were one of them. Didn't want to go with more offset - wanted the tires tucked more so I didn't have to put on fender flares (which I've had a set of Bushwhackers for 4 years now, collecting dust in garage after garage). I've only found aluminum to fit which doesn't make much sense, since they're considerably thicker to make up for the difference in strength. Got lucky with the set of aluminum wheels I have now - Ebay impulse buy that actually worked out! <img src="/forums/images/graemlins/smile.gif" alt="" />
