What gears do you currently have?

If you're running 3.21s with an auto, you'll likely want to re gear. If you have a manual or 3.73, it becomes a bit more of a discussion.

There are plenty of threads on re gearing, though.
I have a six manual but I'm not sure what gears I have this is my first wrangler and I've only had it for 2 months also any idea what size spacers do u think I will need for the 285/70/17 because this is a hole new game to me

Those are only roughly 32.5"x11.5".

You might not need spacers at all. With a 6 speed, they'll be fine regardless of gearing.

Hi Everyone.. looking for advice. I was thinking of going with the Teraflex 2.5" kit that includes Coils and Shocks... local 4x4 store is quoting 617.00 for the Parts. I am thinking me and my brother inlaw can do the install, but they were saying you need to do an alingment when done.. so my question is what is the largest tire I can run now, that would look good after the lift. Also the 4x4 place was saying either way i need to buy spacers even if I am going to change the wheels. For ref I was thinking 285/70/17 Dura... I see they go for 201.00 online.. is there a better tire and price. This will be used mostly for on road with minimal off road for the time being. (have to get the wife ok with going off road and scratching the new toy)..

Thank you

Welcome to the forum.

All Rubicon, Sahara, and sport s JKs come stock with 32" tires. And that's not how warranties work, so I wouldn't worry on that point.

Anybody have real-world experience with BFG ATKO LT285/70R17 mounted on the 17 stock rim without spacers? I have a level spring on but I'm concerned about turnng radius/rubbing. Any help would be appreciated before Monday when I have to decide.

I see Firestone and a few other tire companies now making 275/70/17 tires. These are 11 inches wide and 32.2 tall. Has anyone bought these for use on stock rims?

I have a 2013 Sahara 2dr coming in SOON !...i'm most likely gonna upgrade my tires..nothing crazy, just want more tread really..I'm looking at General Grabber AT.. i can go 275/65-18 which will be stock height and about an inch wider..or 265/70-18 which will be about 1/2 taller then stock and 1/2 wider...again i' really looking for more / deeper tread..while not getting alot heavier so i can maintain fuel mileage..Jeep is gonna be my DD for work about 500 miles /week... I need to go off pavement, no heavy wheeling, for work 4-5 Xs a week..
Funny thing is my decision will probably be made by wether or not i want White letters..the 265s come white letter..the 275s do not...
So i'm kinda thinking 265s..giving me just a little more diameter and i push them out with some 1-1/4" spacers...

Any thoughts?

Thanks boys...

I would recommend a rim that has at least 4.5 inches of backs spacing as your platform, from there you can get into some 285/75/16 or 17 which are 33"x11.2. This is the set up in mine and I love it, no rubbing what so ever and there's still plenty of clearance for light wheeling.

So I am a noob with this and have been looking up info for the past two hours. I thought I had it but than I found out about offset and it threw me off. So I got a question than. Would a 16X8 with a offset of 0 wheel fit with 265/70R-16 tire? I am on a website and it says it wouldn't work but after ive done my research I belive it should. Am I wrong?

That has been my observation. Running 285/70/17s with a 4.5 back spaced 8" wheel (most of the aftermarket wheels) the tread is moved outward and under the fender lip which is the lowest part of the fender. That is where it would make slight contact at the rear when compressed on my 2011 sport.

The same size tire on a stock wheel with a 6.5 back space is inside the lip and has room to move up inside the fender well without making contact with the lip.

I now have a new 2013 2-door Rubi (no lift) with the same size 285/70/17 (33x11) on the stock Rubi wheels and there is no contact with either the fender or inside frame/suspension when fully compressed (not disco'd) She goes full lock turn without rubbing so no need to limit that with washers.

I have not had it long enough to get out where I've wanted to disco the swaybar so that observation is yet to come.

tire selection for stock wheels

2012 jku sport s
17" wheels

my question is, what is a good, agressive tread tire that is the same hgt as stock, but maybe a bit wider, that wont cause problems?

im planning on adding a leveling kit that would add a bit of lift (1" +/-) so keep that in mind.

also what speedometer/anti skid issues would show up if i did go with a larger diameter tire on stock rims and what are the easiest corrections?

AEV Procal...that will be your best friend when you start to mod. Foxes the Speedo, tire pressure, higher idle for winching and much more.

Hello all.

I'm looking to buy a set of steel wheels for my '13 JK that I can mount some more aggressive tires on for the spring/summer/fall months.

I want 16 or 17 inch wheels. I want to be able to mount a 33x12.50 R16 or 17 (or similar) tires on them.

I'm wondering what specs the wheels need to have and what, if any, other vehicles out there might have stock OE wheels that will work with those size tires.

I'm pretty inept with it comes to wheels and tires, just learning. Thanks for your help.

Onroad, no. If you flex the suspension offroad, probably.

I'm not planning on buying spacers or anything to prevent rubbing though. Would 265/75/16 rub more than 285/75/16? Sorry if that's a stupid question, I'm really bad with these numbers.

Ok, I'm new here, first post. (This forum is awesome BTW).

I've read this entire thread and taken notes, but I'm a bit overwhelmed and not entirely sure. I have a 2013 2-door Sport ordered and I want to order new wheels and tires. I do not want spacers or a lift. I think I have it narrowed down to a 17x8 or 17x9 rim with 4.5" BS with 285/70/17 Duratracs. I think from what I've read that there will be no issues on the road or with turning. But off-road might there be some rubbing or any contact? Or is it ok? I would not be disconnecting.

If there will be rubbing with this combo, then what would be the best tire size to go with on 16" or 17" rims with 4.5" BS that would have no rubbing whatsoever?

No 265/75/16 would rub less. It's smaller tire.

Once you got to 265/75-16's you will in a few weeks start looking at them and start thinking they look too small so you will want to go 285's right off the bat as intitial cost is not much different but if you go with the 285's to begin with.
