I am currently running Toyo Open Country M/T's 35/12.50/18. Unfortunately I still have the stocker Rubi wheel and tire on the back. My buddy is going bigger, and said he will give me a 35/12.50/15 Goodyear Wrangler MTR for free if I want it for a spare. Without getting into the issues of mounting it on the tailgate, can anyone tell me if a 15" rim will clear the brakes if I am running Spidertrax 1.5" spacers?

Jeep:
07 Rubi 2dr
5" Skyjacker Long Arm

 

I had 1/8" spacers to clear my 15" rims and it worked but then I took them off and ground down the caliper a bit and reinstalled without the spacers.

It would appear from BryGuy's great work that the ProComp 8179s clear with no issues. That's what I'm going with!
