Sunday purchased new (First Jeep) 2012 Blalck Forest Green Sport. First order of business is lift tire and wheels. After reading hours of previous post regarding back spacing and tire sizes, I still have a question of my own. Co-worker purchased five new RBP 94R 17X9 (black) rims for his 2011 JK, after purchasing he found a good deal on set of tires and wheels together so the rims sat in his garage. He made me an offer I couldnt refuse ($450) for all five he paid $1,300. I called RBP to give them the numbers on the boxes to confirm 4.50 back spacing. They said the backspacing on the set I have is 5" (I know ouch). A local shop is putting Teraflex 2.5 lift on Friday and I want to have the tires on the new rims ready to go when lift is done. I only want a 33" tire and was getting quotes on 285/70/17 Trail Grapplers. What size tire should I order in that range (33") to assist with the rims I now own that have 5" back spacing, would rather not use spacers. First post, so thanks for any responses.

 

I think you'll be just fine with the 285s..stock wheels have 6.25 backspacing so yours will still be pushed out 1.25" for a little additional clearance.

 

Thanks for the reply, I was hoping to hear that!
