Im about to pick up another 4 door and the owner has 17x9 Rugged ridges on it as well as spider spacers. the tires stick out a solid 2-3 inches past fenders.

Whats the backspacing on those wheel. Quadratec doesnt list it? I will most likely pull the spacers off when I get it home.

The b.s. of those wheels is 4.75" you do not need those spacers at all. I'd take them off for sure.
Good luck with your new to you rig. Those are nice wheels too.

 

If you're still running stock tires like your profile suggests, you don't need spacers. I believe the only way you'd need spacers would be if you ran 37s. I think you'd probably even be fine with 35s depending on the lift.

Those are good looking wheels. They'd be my first choice if the backspacing was 4.5 or less as I'm planning on 37s.
