Hey everyone. I have a 99 Sahara. It's got a small lift in it, and I was wondering what size tires I could get without worrying about rubbing. I was hoping to get 33's. What does a stock Wranger get without rubbing? I only ask because I did not put the lift in, so I wanna be sure it wont rub. Thanks.

Questions:
 
What size lift is it? Pics would help. If tall enough, 33's will fit vertically and be okay offroad when flexing and stuffing the tires up into the fender.
 
What kind of wheels do you have? If they are stock, you will have issues rubbing at full lock/turn. If they are aftermarket, you're probably better off as they likely have less than the 5.5" of backspacing (smaller number = less 'tucked in' they are).
 
If you have a shorter lift, say around 3" total, you CAN run 33's, but you may want to extend the bumpstop so they don't fully stuff into the fender when offroad. Otherwise, you risk the tires getting sliced by the metal or the tires destroying the flares/fenders.
 
I have 4.5" total lift (3.25" suspension and 1.25" body) and run 33's without any problems. I have 4.25" of backspacing and only have a bit of rubbing when offoad at full turn and when flexed.

Hmm by soph321

Cool thanks. I actually don't know how big the lift is, it only looks like an inch or two inches tops. I bought it with the lift already installed. So until I get a bigger lift, I'm going to guess that I'll go smaller. I have American Racing Rims on it, could I at least go with a wider tire?

With the wider tire, you still have to worry about rubbing the control arms and/or frame when making a tight turn. Given that you have AR wheels, you MIGHT be okay, as they usually have 4.25" or so of backspacing MAX (though there are probably exceptions).
 
Sounds like you may just have a budget boost. Do you have spacers on top of the springs at all 4 corners? Pics of the suspension components and/or pics of the body/frame mounting points would help me figure out your height and I could provide better ideas then.

Looking to add a 3" lift and 35"x12.5X17 tires to new 4 dr. Will probably have dealer do this. Anything I need to know? Anything else I would need added? Will the 6 cyl. have enough power? Will 2008 have a 8cyl option?

Another '08 Unlimited Question by jeepincarnate

I just put my order in today for an '08 Sahara. While I'd love to go hog wild with mods, I've heard horror stories of the complexity of lifting the 4 drs. Also, it has to function as a daily driver (all excuses for "the wife won't let me").
 
So, here is my question:
 
What is the largest sized tire and wheel package I can throw under this pup without any rubbing? Does anyone know where I can find rims? (I doubt they've revolutionized their wheel specs for '08, but I can't seem to find any dealers that carry what I'm looking for online). Ideally, I want powder coat black rims between 17 and 18" with 31 or 32"rs. If anyone knows of any pitfalls with this set-up, or if I can safely go bigger, please alert me.
 
Thanks!

31 all terrian BFG's on TJ by sah538

After talking to a tire dealer about putting 31 inch tires on my TJ he told me that they would rub the control arms but it could be done anyways. Is it not a good idea to go with the 31's on a stock jeep?

I had 31's on my 98 stock TJ, they definitely rubbed . . . alot. It cut my turn radius down considerably, but after a while I got used to it. They looked great and fit on my factory rims, which was a plus, but in retrospect a lift would have been a better first investment. The larger tires also threw my speedometer off resulting in couple of tickets in strictly patrolled areas. I would recomment having that adjusted as well.

31" tall tires are NOT the culprit in the rubbing. It is the WIDTH of the tire, most likely 10.5 vs the 'stock' 30x9.5 available with the Sport models.
 
You can fix this problem in a few ways:
1. Make steering stop adjustments as shown at 4x4xplor.com's website
2. Go with wheels with less backspacing than the stock 5.5" that come on most Jeeps (other than Rubicons).
3. Add wheel spacers. I run 1.25" Spidertrax spacers on my stock Jeep Canyon wheels so I have an effective backspacing of 4.25". They stick out a bit more. I have 33x12.5" tires.
 
31" tall tires are more likely rub when flexing offroad and stuff a bit into the fender well. Proper fix for that is to adjust the bumpstops located 'inside' the spring at the top. If you look at that area, you'll see what I mean.
 
When I put my 33's on, I also regeared my differentials from 4.10 to 4.88 (2.5L engine here). That combination of 4.88, 33's and my transmission actually made my speedo MORE accurate than it was previously (I had gone from the stock 28" tires to 30" tires prior to the 33's).
 
Getting the speedo set back to accurate will require you to know your tire size and your current differential gearing. Look at this information and you can tell which speedo gear you'd need.

A lift does nothing more than allow to fit those bigger tires. If you only want to go to 31's, a lift isn't required. Having said that, Jeeps do LOOK better when lifted a bit and they perform even better offroad when lifted as you have better clearance under the axles with those larger tires.
