Here's a link I found with a few specs of stock Jeep wheels.

32s with no lift is doable, especially with those wheels, but certainly not recommended. 31s are generally considered max with no lift. With the 32s you will have no flex without taking out your flares. Get a 2" BB lift.

It depends on which wheel you have from the factory on your jeep. Post a picture of the wheels and I can tell you exactly what the measurements for that wheel are.
12-28-2008 01:04 PM
G54 Your wheels should be 15"x7 or 8 - not sure. Backspacing is probably 5.75", someone may correct me if I'm wrong. Black steel wheels as pictured below are 15x8 with about 3.75 - 4" of BS. You can get them black or chrome. Cragers are generally cheaper by about $15, but the ProComp Rockcrawlers are arguably a little better quality as far as the welds go. Either can be had for under $50 each.

BTW - the only dumb questions are the ones you don't ask. But don't forget the "search" feature and remember Google is your friend. Welcome to WF!

In all honesty, I have the money to go ahead and get new wheels, but I'm definately not the type of person who is worried about things like, "Five points are the only way to go cause they look the best," or "These rims are awesome because they are $500 a piece." I am looking for something very simple, plain, and more importantly effective in not causing issues such as "rubbing suspension parts", or decreasing turn radius much. I'd like to stick to 15" because, to me, going bigger with wheels simply means more cost.

Again, I really appreciate any comments or advice and will certainly pass any knowledge gained on to the next "newb"...Lol I love that word.

Yes that is correct. Commercial vehicles such and buses and semi's , it is illegal to run retreads over the road on the forward steering axle.

Although TJ's are personal owned vehicle and it is not illegal to run retreads on the front on the road.

Would I do it...no, But many do to save a buck.

G54 So...back to the OP question. If you don't plan to wheel it - you can go with 31x10.5 with no lift - max. It would be better on aftermarket wheels with 4" or so of backspacing, or install wheel spacers. Steel wheels like that are about $50 each. 8" wide wheels will be fine. As was said, 31x10.5s will rub on turning with factory wheels.

For 32x11.50s, you will need a 2" budget boost (coil spacers on top of the springs) or 2" spring lift (new, longer springs). Pretty inexpensive and not hard to install. You could wheel with that setup but a 1" - 1.25" body lift on top of it would give you more room to flex.

For 33s you will need at least the 2" lift if you don't plan to wheel it or go over any bumps. Many people run 33s with 2" lift and 1" body lift without any problems - but again - you will want 3.75 -4" of backspacing on your wheels to get them away from suspension parts on turns. (I think the wider stance looks better too) Ideally for 33s a 4" lift is recommended by most people if you plan to wheel it.

A few other issues to consider as you get closer to 33s are gearing, mileage, spare tire carriers, and possible driveline vibes to correct.

My advise from my experience of making stupid, rash decisions for instant gratification - stay stock until you're ready to do it right, and research all your options thoroughly.

speepdaedeesi Tire Retread & Repair Information Bureau | RUBBER ON THE ROAD - Issues & Answers - Is Safety Really An Issue With Retreaded Tires?

Is Safety Really An Issue With Retreaded Tires?
(And what about all that rubber on the road?)

The biggest problem the retread industry has is the issue of safety, according to a spokesperson for TRIB, the Tire Retread Information Bureau.

The reality is very different from the perception most people have, and that's the problem. Retreaded tires are as safe as comparable new tires, a fact that has been proven by millions of users over many years. Yet, some people are still afraid to use retreads.

Virtually every commercial airline in the world routinely uses retreaded tires on even their largest passenger jets. Thousands of school buses, municipal buses, trucks, taxis, race cars, and millions of motorists safely use retreaded tires. Retreads are also safely used on emergency vehicles such as fire engines and ambulances.

Still, the issue of safety lingers in the minds of many prospective users of retreads. They will often cite rubber on the road as "proof" that retreads can't be as safe as new tires.

The fact is, a large percentage of rubber on the road comes form new tires. In his article, "Tire Life and Failure Analysis", Lawrence R. Sperberg of Probe Scientific Laboratory, El Paso, Texas writes:

The writer once conducted an experiment close to the New Mexico-Arizona border on Interstate 10. He parked, and for a distance of roughly 150 feet on either side of the westbound lanes, he searched and catalogued the tire debris found on the highway shoulders and in the median , taking care to discard duplicate debris from the same tire failures. He found that a different tire has failed for each eight inches of highway length and that roughly two thirds of the failures were new non-retreaded tires and one third were from retreaded tires. He repeated the experiment at selected places between Palo Alto, California and Akron, Ohio with much the same results, although the eight inches between tire failures was never again achieved, although it was approached. That one study consumed over four man hours at the Interstate 10 location cited, plus additional time taken later to recheck everything.

TRIB, the Tire Retread Information Bureau, has a mission to educate consumers and government officials about the environmental and economic advantages of retreaded tires. For additional information, contact TRIB. info@retread.org

speepdaedeesi didnt know you were driving a commercial vehicle.




just kinda fyi..

you get a 2 year 24k mile limited warranty on treadrights.

they use the most high tech process available to make their retreads. lazers and shit..


Remanufacturing Info


HOW A TIRE IS REMANUFACTURED:

Remanufacturing tires is a valuable resource in saving our environment. While the tread of the tire may be worn away from highway use, many tire casings are valuable for their recycling potential. TreadWright, Inc. has 30 years of experience in providing high quality retread tires, saving the user money and saving our environment.

Remanufacturing a tire is accomplished in several steps.

1.
Casings are acquired from tire dealers who are familiar with the process and understand the proper storage of a used casing until they can be picked up. When the tire is received at our remanufacturing plant, it is again stored in a vertical position on racks where no tire is placed on top of it which could crush the sidewall and cause serious internal damage. This quality control feature costs us more to do, but it is important to the quality of the tire.
2.
Inspection of each casing is done in several stages. First, the tire dealer is setting aside casings that could possibly be used for recycling. The next visual inspection is done as the tires are accepted for transport to our remanufacturing plant. And finally, the casing is brought into our plant inspection department where it is carefully inspected under excellent lighting, with non-destructive sophisticated inspection equipment that is available to the industry. Casings also receive a complete rigorous visual inspection at this point. Accepted casings are now placed into the remanufacturing process.
3.
The process in the casings begins with a high speed buffing
which mechanically removes the remaining old tread. Today's buffers are extremely accurate and will remove the proper amount of old rubber while truing the tire to an exact specified, laser ensured, diameter and radius.
4.
Application of new rubber to the tread area is the next step. The unvulcanized tread rubber is applied to the tire with a preset adhesive that begins the bonding of the new tread rubber to the casing. The tire is set aside for the adhesive to set.
5.
Computer balance. We rebalance the tire to insure smooth running & good performance. Warranted to be less than 7 oz.
6.
Molding of the new tire tread is the next step. The tire casing with the new unvulcanized tread rubber is placed in a rigid mold which contains the tread design in the tread area. The mold is heated and the rubber in the tread area vulcanizes and adheres to the casing with the new tread design molded in. This vulcanization process also bonds the tread rubber to the casing through the use of heat, pressure and time.
7.
Compression-Cured in automatic press & segmented matrices.
Compression-cure is a superior method of remanufacturing Radial tires. It provides constant high pressure during cure resulting in a high density bond like new curing. The result: A high quality like new tire!
8. Trimming of the completed tire removes any excess rubber. The tire is then placed into racked storage to await a final inspection.
9.
A final inspection of the tire is then performed that insures that only tires that meet industry quality standards are allowed to leave the remanufacturing plant. The tire is now ready to return to full service and a second (or third) life as a safe and economical alternative to high priced new tires.
10.
Remanufactured tires are your best tire value. Truckers, fleet operators and consumers can expect substantial savings by using remanufactured tires. For additional information on remanufactured tires and to purchase tires, contact TreadWright, Inc.








it uses 22 gallons of oil to manufacture one new truck tire. Most of the oil is found in the casing, which is reused in the remanufacturing process. As a result, it takes only 7 gallons of oil to produce a quality remanufactured tire. It also keeps the casing from going to a landfill.


also, i can understand retreads being illegal on the fort tires of a commercial vehicle- front wheel blowout=better chance for losing control... huge trucks will definately be hard to control in a blowout situation. but i dare you to find a trucker that doesnt use retreads on his other 16 wheels.


but remember not everyone uses the same process to make retreads. alot are poor quality.

not knocking your opinion, just trying to maybe make you see it through more open eyes.
12-27-2008 11:36 AM
Atthehop I would never put retreads on the front, in fact it is illegal to put retreads on the front of any commercial vehicle.

speepdaedeesi i have 30x9.5 with a aggressive all terrain on mine now. they dont look bad, but they dont look huge either.

im going to go with 31x10.5, because i dont want to mess with a lift until i have the time and money to do a real lift.

one thing you might look into, which im doing, is getting used tires. i put a wanted ad on craigslist, and have been surfing the jeep forums and clubs in my area, and ive had about 7 or 8 sets of 30-31 inch tires offered to me in the last week with prices between 100 and 250. MUCH cheaper, especially if you plan to upgrade later.

ive setteled on a set of 4 WILD COUNTRY 31x10.5 mud terrains with alot of tread left for 150 bucks. these new are 148 per tire at the local retail tire place.

also look into retreads, i almost did these but its cheaper to get used. im definately getting retreads when i put a lift on. people have had nothing but good things to say about this company!

jwh21236 Thanks... If I were to want to put say 33 inch tires on, I'm guessing I should probably get 15x10.5 inch wheels with at least a 1" body lift?

What recommendations can you make that would make it easiest to put a little bigger tires on and NOT have the Jeep look like it is strictly used for offroad. I just want between 31-33's I think, on 15" wheels. What setup do you recommend the most?

Your opinion is greatly appreciated!

Atthehop 30x9.5 is the max with no rubbing, the 31x10.5 will rub on full turns but you can shim the wheel stops to prevent it and not noitce a real differnece in full turns.

Tire & Wheel Question...

Hi all,

My question is what's the max size tire that can be fitted to a stock 99 TJ with stock wheels without rubbing. If I buy 31x10.50, or even bigger, when will either the width be too big for the wheel, or the tire begin to rub when turning?

-Thanks
