I have been looking at a +20 offset for clearance. Some others on here have been as much as +12 offset but that gives about 1.5 or more inches of tire outside the fender.

Is it a Rubicon, or a different Gladiator with a Rubicon suspension? There are two different axle widths that vary by model.

I am looking at 17x8.5s with 0 offset. My factory wheels are even with the edge of the flares so I think centered wheels will put them at about 1 1/2 inches out. Is this correct? Are the factory wheels about 44 mm offset?
