Head spinning and crossed eyed.....Advice Needed!

Hey guys and gals,

Just bought my first 4 door Unlimited sport. Been researching for days on tires and wheels. I think I'm about ready to go crazy. Any help with the following questions would be greatly appreciated. Seems like the more I read the more crazy I get.

First off I want to keep it pretty close to stock as I can but would like to go with 33's. I'm mostly a street driver to and from work. With maybe a trip here and there to the woods for hunting purposes.

I was thinking 33x12.50r15 duratrac on pro comp 7031 (15x8) with possible terraflex leveling kit.

Questions:

1. Will there be any rubbing with this set-up?

2. Will there be a noticeable loss of power?

I want to stay away from re-gearing and all that stuff. The budget just doesn't call for it.

If you have any suggestion please throw them my way.

Thanks
Jason

Questions:

1. Will there be any rubbing with this set-up? Nope, 33s are pretty easy fit on a JKU

2. Will there be a noticeable loss of power? Not really, many of us on here are running 34/35s and with the post 2012 motors they seem to keep up

I want to stay away from re-gearing and all that stuff. The budget just doesn't call for it.

So, you will hear from many others; "why not a 2.5" lift and run 35s?" 35 inch tires seem to look the best on the 4-doors, I just put on 315/70-17 Cooper STT Tires, which measure 34" mounted. I have not seen any real drop in power, and no real change to drive ability. And, I think it looks pretty darn good.

I spent less than $400 for the lift, with installation. I bought the LRG 106 rims from 4 Wheel Parts got them on a buy 3 get 1 free deal.

As always, actual results may vary. Good luck, and welcome to the Club!

33x12.5x15.......15" rims? Did your JKU come with 16" or 17" rims. Have to be very careful with 15" rims as the wrong backspace will cause clearance issues with brake calipers.

The jeep came with 225/75r16.

I appreciate your help. I know this question has probably been asked a million times over.

Thanks again
Jason

Does your JKU have 3.21 or 3.73 gears? Assuming 3.21, I would go with the lightest 33's I could fine. Cooper AT/3 in P metric version. Weight is your enemy as much as diameter.

I believe anything bigger than 255mm wide or 32" tall will rub at some time. It may only be in heavy flex situations at full steering lock but they will rub. The good new is the rubbing may only be against the front plastic air dam.

I put 285/75/17's (33's) on my JKUR and it looked like they would rub but only on the air dam. Before that happened I lifted it 2.5" and have never heard them hit. My jeep is 3.73 gears and it handles fine with my light weight 33's. I personally would not go bigger than 33's on a DD. Acceleration and braking both take a hit with the size and weight of 35's.

You could get a nice upgrade by buying a set of Rubicon take-off wheels. $1000 for a set of 5 wheels & tires that bolt right up to your Jeep.

Thanks for the replies. I greatly appreciate everything. This is all new to me.

1. Whats considered a lightweight tire in pounds?

I know the TA KO2 are around 56 pounds. Is this a heavy tire?

One other option...I kept my STOCK wheels and went with stock size tires...they call it Pizza cutters when it is a Duratrac this narrow with this tread pattern. It works great for me.
