Tire question.

I've been doing my homework, searching forums and asking around but get no where. It's a fairly easy question. I bought a 4.5' RC lift and 15' 3.75 back spacing rock crawler rims. Do I need 33's or is that something that's good to have? It's not my daily so it's all about wheeling functionality. What would you guys go with?

If its an offload rig only I would go with the 33's for more ground clearance,you may need to trim some sheetmetal to make em fit with out rubbing but I think you will find then to be a very good size for most trails.

You "need" what ever size tire you *want*. It has nothing to do with lift height.
You choose lift height to allow for tire size...
The RC 4.5" lift, per RC, will clear 32x11.50, so some trimming and bump stopping will be required to fit 33" tires.
As for the rims it's good that you got better back spacing, but what WIDTH did you get?

My personal choice would be a 33x10.50. Two extra inches of differential clearance and less weight than a 12.50.
One other thing to consider: 33" tires will probably make you want better gears, and if you're doing the gears you might as well get lockers

I got 15x8 which should handle 33's no problem.

Bigger tires means more diff clearance and more stability. I'd def go 33s at that height.
