However, I am now rubbing (not really bad) with the new Duratracs on the inside of the fender wheel even after some trimming. The tires that were replaced were 315/70/17 BF Goodrich AT KO. I really cannot do a lift at the moment, but could do new wheels with a different offset if it would help with the problem. My torsion bars are cranked now and I am currently running a Gear Alloy 714C (possibly +10mm?) but do not know the offset and cannot find it. I have fender flares as well. Do I need a 0 offset wheel or something like a -6? Thanks in advance for any help provided!
Honestly, without knowing the offset or rim width you have now it's almost impossible to tell you what you need.
From your post I'm assuming you're rubbing on either the front or back of the inner fender with the outside of your tire correct? If that's the case you need a more positive offset, not negative. But then you also need to check how much clearance you have between your tire and the suspension now to make sure you can go with a more positive offset. But again, we can't tell you what's going to fix your problem without knowing what's causing the problem.... so we need some specs.
The offset of the wheel should be stamped on the backside of one of the spokes. So take a look there first. Otherwise you're going to need to do some measuring. We need the rim width also so you might as well measure that at the same time. Measure from the outer lip of the wheel to the inner lip of the wheel and round down to the nearest inch or half inch. To find out the backspacing you need to put a flat edge along the backside of the rim. It can only be touching the rim, not the tire otherwise you aren't getting the right measurement. Once you have it along the backside of the rim measure the distance from that flat edge to the mounting surface of the wheel. That's your backspacing and we can determine your offset based on the rim width and backspacing.
