Ok tires really aren't my thing and I find all of the numbers super confusing any help here would be appreciated greatly.

Ok here is what I have: I have the 18 inch stock Sahara rims and currently am using P255/70R18... I have a 2inch BB but the heavy Mopar Bumpers and a 10,000 lb. winch.

Here is what I want: Bigger tires lol
I was looking at 35x12.50R18LT INTERCO TrXus STS All Terrain Radial Tire

Will these fit? Rubbing? Backspacing issues?

I want to keep my Rims for now but get new tires.

 

That is a wide tire, especially for stock rims. You may have rubbing issues while at full turn.

 

The FAQ's are a good place to start for the basics. Try the Wheels & Tires area, it has info on lift heights and backspacing for 35's.

 

The money you would save switching to a 16 inch rim would prob almost buy you the wheels, then u can sell rims to recoup even more money. Plus u will have to run spacers with stock wheels so they cost like 200 bucks. 16 or 17 inch rims are better for offroad than 18s because you got more sidewall flex if u care about off road capability. The smaller rims will pay for themselves, ditch the 18s unless u really like the way they look.

You cannot run those tires on stock wheels without spacers, they will rub really bad and cause all sorts of problems.
