285/70/17 on a CJ

[Flundertaker]

needed tires to hold me over till my full rebuild. found a local set of 17x8 5x5.5 procomp wheels with 285/70/17 mud terrain tires for a decent price so I picked them up. a couple of observations: these were off a mid 90's full size bronco so the backspacing was more than I wanted. They fit my CJ but can rub the front springs at full lock. the rears clear the springs by about 3/4" on each side. The tires are E load range 10 ply and make my ride even worse than before and worse than I ever thought possible. Even with 18-20psi they are rock hard on the light weight jeep. if the wheels had a bit less backspacing they would fit great, as they are now the tires are slightly tucked with none sticking out past the factory flare. I think 285/70 translates to something slightly less than 33" so I have no fitment issues related to the height of the tire. Overall, I am happy. I gave $400 for the set. My jeep looks much better and I an safer than driving around on 10 year old dry rotting rubber.

Could always put spacers on each wheel.

Could always put spacers on each wheel.

Spacers add alot of extra stress to the bearings. I try to avoid them at all cost.

As for the tires due to side wall and load rating try dropping it to 15psi

Your rear tires are gonna rub on your frame under heavy articulation. i have 1 1/4" - 1 1/2" between sidewall and springs and mine rub when out 4 wheeling.... Just something to keep in mind.
