Yeah, they are a bit pricey. But they are about the only option in that size. You could look at some tires in the stock size (255/75/17), but most of the good ones are damn close to the price of the 255/80.

A 285/75/17 is a 34" tire. That is going to be pushing it on stock suspension, though there have been a few people to temporarily run 35s on stock suspension. If I was in your shoes, I would go for it and just be insanely careful and cautious until I got the lift. But I'm crazy like that.

Would I need any gear changes for this size tire? If not, I am going for it and hope to pick it up soon.

What year Jeep, what transmission, and what is your current gear?

It is a 2012 Wrangler Rubicon Unlimited. Manual Transmission. I think (I'm new to this but learning) first gear ratio 4.46, Transmission case 4.00 (Lo), Axle 4.10 and crawl ration 73.1.

Then no, you would not need to regear.

When offroad, yes, more than likely you would get a bit of fender rubbing. Not nearly as bad as if you disconnected of course. On road, probably not.

If you decide to trim, this might help (if you haven't already seen it):

im not dead set against a lift. but i need licenses plates before i mod it to much. and ive been down the lift it for crazy big tires before and it always leads to other things and more costs. i just really dont want to loose my gas mileage. 24 on the interstate and 20 in town.

how much articulation are we talking before rubing? i really try to keep all 4 on the ground.

4fit - Is there anything else I will need to order besides the Terflex 2/5" coil lift and Blistien shocks. I see other post where people add other stuff and I want to make sure I order what I need to ensure it is still a good dd.

What do do with the TPMS sensors and how do you reprogram the speedo to recognize the new size?

This is some great info. I was at a Goodyear dealer today and didn't believe him when he said i could go with 285/70r17's on my stock JK rims. I'll be sure and get some spacers before I take it in. Once I get the tires I'll find rims and switch the tires over.

Thanks again for all the good info.

if you are okay with loosing some turn radius you can put a washer behind the steer stops and keep the stock wheels

Washer with spacers or does the washer eliminate the need for spacers?

Washers only. The reason you need spacers is so the tire doesn't rub on the frame at lock. Stop it from turning that far and no need for spacers

To be honest, I'm not 100% certain as I have never had to look into it. Someone such as ESP could probably shed a little light on that subject since he ran the 33x12.5x15 Duratracs with a very small lift for a little while. Seems like it was the Daystar 3/4" spacer lift.

Everything required comes with the kit. However, after install, you may decide that you want an adjustable trackbar to recenter the front axle. You may also decide that you want front lower control arms if you experience any flightyness in your steering. However, you may be just fine without any of this.

Is it best to get the adjustable trackbar right away to recenter the front axle and wait on the front lower control arms (in case of flightyness) or do most people end up doing both in the long run?

Depends on if the axle gets too far off center or if the steering becomes very flighty. There are many people out there running the kit with nothing else added.

My recommendation would be to install just the kit and see what you think. If you need the other components, get them at that time.

Hi everyone, great thread and for a noob I'm learning a lot about tires. Currently I'm running stock 16's on my '12 JK. I'm looking for more aggressive looking tires (duratracs based off of this and other threads) for my daily ride. I don't off road (at least yet) and don't want to kill my MPG. I'm strongly considering the TF 1.5" leveling kit in the near future and eventually want to change out the stock wheels. I like the look of the wider tires but don't want anything ridiculous (sticking out way past the fenders).

My question is I this, what would you recommend for me based off of the above? I think the 33's look great but how wide could I go without spacers? And what do spacers do to my ride, they sound expensive and avoidable with different wheels.

Based on your description, I would say you need to stick with a 16" (or larger) wheel. Most of the 15" wheels have a very shallow backspacing in order to clear the brake calipers. This of course pushes the wheel/tire further outward.

If you are considering getting wheels, then I would urge you to skip the spacers and save a little while longer and get the wheels. Quality spacers will run you about $200 for the set of 4. These will effectively take the backspacing of your stock wheels down to 4.75" and will allow you to run something like a 285+ tire without issue. But new wheels would be the way to go.

For you, I would recommend something such as a 16x8.5" wheel with 4.5" backspacing and a tire such as a 285/75/16 (33x11). This will widen the stance of your rig without causing the wheels/tires to protrude too far out from the fender. This is the exact setup I run (can see pics somewhere in this thread). Of course, you could run a much wider tire on this setup if you wanted to.
