4x4s have a 2" factory block in the rear yes.

Hey everybody. So I have a 2006 4x4 with a 2" leveling kit and am running 285/70r17 and am having no rubbing issues. I have factory 6 lug 17" rims an d want to upgrade to 315/70r17 or 35/12.5r17 tires. I know the 35s are about a half an inch larger than the 315su and would like to keep my factory rims. Will thy rub? If so what is the max backspacing I could get if I got new rims? Thanks for th input everybody.

correct me if I'm wrong but you cant fit a 12.5" wide tire on a stock 7.5" wide rim. 295mm or 11.6" wide tire is max on a 7.5" wide stock rim!

You can fit a 12.50 on a 7.5" wide rim.

Me and my friend just got a 345/75/16 mounted on his 8.5" wide rim. That's a 13.50

Im not sure how your 8.5" rim applys to a 7.5" stock rim. 1" of rim does not equal 1" of tire width its normally about 1.55".look at all the tire manufacturers web sites they tell you the rim needed. 1.55x7.5 wide rim is 11.625. 1.5x8.5 wide is 13.175 so I'm not suprised you fit a 13.5 on a 8.5 rim.

Well the recommended rim width for the tire was 9.5-11" wide. I should have mentioned that earlier but I was just trying to show that you can fit in the outer ranges of the recommended rim width, plus people put 35x12.50 on there stock wheels all the time with a leveling kit. It's literally the most common mod.

If the tires caused something to fail then yes, but I'm not sure what they could really mess up. Hitting the fenders is about all I could see the tires damaging and that isn't dependent on wether or not you mounted the tire on a wheel within the recommended specs.
