I think my rims are true 8" wides. As far as the rock rail, yeah it's pretty close. Maybe 2-3" clearnance. But the angle of the drive shaft means it'll never hit as it travels in an arc around it. Any larger and I'd be really worried. I plan to ditch my Rubi Rails at some point anyway in favor of the TeraFlex ones more than likely.

 

I'm not sure how aggressive I want to get when I replace the MTs on my Rubicon. How would you compare the BF AT v. BF MT v. the Duratracs v. the MTR kevlar? The Duratracs are in a different category (on/off road commercial traction) on the tire web sites than the other tires but seem comparable to the BF ATs. Are the Duratracs more like an AT?
