Wheel Size Questions

I have a 2003 TJ with the 4.25 zone combo lift on it. I'm running the stock wheels with 33x12.5 tires and it's pretty close to rubbing the sidewall in the back. So i'm looking to get some new wheels that will work for my current setup and will work if I eventually switch to 35x12.5s

I'm looking at some pro comps that are 15x8 with 3.75 backspacing. Will these work for me now and if i were to run 35s in the furture?

Personally I wouldn't run anything less than 10.5 with a 12.5 tire...again, that's just me.
Are you looking for a steel wheel or something that you can show off a little more?

You can check out what we've got on our website if you'd like: Pro Comp Jeep Wheels

Any questions, just let us know!

I've been told 8 inch width is ideal if you air down while off road.

I run 31x10.5 on my TJ on the stock 15x8 wheel. Then again, I drive on-road more (I know, I know, I shouldn't be lol)
I've always been under the impression that you shouldn't exceed 4" difference between wheel and tire, and me staying on the safe side all the time, I opt for +/- 2"
Just be sure to get the air pressure right so the tires don't wear prematurely

And send some pics our way! I'm kinda interested to see what she'll look like

I agree with the 15x8 wheel recommendation for 33x12.50 or 35x12.50 tires, that's the best width for a offroad Jeep where the owner will be airing the tires down. It takes less air pressure to hold a tire safely against two edges 8" apart than when they are 10" apart. That simply means it's less likely for aired down tires to unseat from 15x8 wheels than it is 15x10 wheels. The 15x8 is fine on the road too, that's all I've run the past 19 years of TJ ownership.

15x10 would be fine for a purely street Jeep though.

Any recommendation on the 3.75 back spacing? That's my real concern. I want to make sure i won't have any issues if i ever switch to 35s. I think I'll be good but there's some much information out there I think i just confused myself more then helped.

3.75" of backspacing is fine for up to 35's.

I wouldn't run 15" wheels for several reason. Among those being that if you go to 35's you will have to much rubber, IMO, and you will have difficulty upgrading to a decent brake size. I know it's a painful process. Tires in themselves can be a mind twisting selection especially if all options are open. I went with 16"'wheels which left me with metric tires as my only option but I am happy with my setup. I don't like the look of big tires on 15's.

Yeah I didn't think about the brake upgrade that would need to be done to accommodate 35s. I think at this point, 35's are at least a year or so out that I'll go with 15x8 for now with my 33s and sell them when I upgrade tires.

I guess "to much rubber" is a personal preference. There are plenty of options out there for tires to fit a 15" rim. Keep the 15s and purchase a set of Black Magic Brake Pads and the Vanco Big Brake Kit

I went to 16" wheels a few years back and it turned out to be a huge mistake. Wound up costing about $250 more for a set of tires in the 16" size, and all that is available in 16" tires are load range "E" which have stiffer sidewalls and are much heavier. Earlier this year when I upgraded to 35's, I spent the money and bought new 15" x 8" rims.

Upgrading brakes isn't a problem...Vanco makes a brake kit for 15" wheels.

The additional sidewall height given by 15" wheels for 35" tires works awesome to help the tire flex more easily which gives more traction for really tough trails. Having run that combination for 12-13 years, I love it. 15" wheels and 35" tires are extremely common because that combination works so well offroad. I don't really care about looks where that is concerned.
