Largest tire size for stock XJ?

[522fireball]

Looking to get new tires, and wondering what's the largest size I could put on it without any mods or tire rub on tight turns. I'm running 235/75/15. While rebuilding the motor, I "borrowed" the tires from my 99 Ford Ex after I sold it, 245/75/16, with no tire rub, but the rear wouldn't tack the 16" rims. So I will be using my BII rims, and would like something equal in height of the 245/75/16, but on a 15" rim. Any suggestions would be greatly appreciated.
Thanks in advance.

I have an 08 4dr and have 16" stock wheels, I put 285/75/16 on them and had to raise the jeep 2". 265/75/16 is the largest that would work without lifting it. There is a tire sight called tirerack.com, it has a conversion table that might help. check it out and see. And if you want to get a good price, I got 5- 285/75/16 super swamper TRXUS tires for around 800.00 shipped and installed from a web site that has really good deals on jeep stuff. If you want it, let me know. They also give a 10% military discount. Check out my pictures of mine, there are some of the tires.

well that also depends on if you're willing/wanting to do any cutting too.
30x9.50x15 is (if memory is correct) the "biggest" you can go with out any modification. anything wider you run the chance of rub in tight turns.
now if you like the 31x10.50x15, you'll have to either lift it or do some "light" trimming in the wheel well areas. not to mention probably readjusting the turn-stops to keep from any tire rub in those tight turns. (that's what trees & or boulders are for right? lol)

personaly i've run the 31 A/T's on my old (1985) dodge ramcharger (off-name brand) for almost 5 years & had no problems with them & never got stuck anywhere.

now why in the hell r u bringing up a ram charger if the man is asking about a cherokee . . . didn't you read that he does not want to modify it???? and since when have xj's have 16 inch rims from the factory???? Las time i checked the last year of the xj is 2001 (unless you're in india) so . . .


to finaly answer the mans question 31x9.5x15 is the closest size to his 245/75's without any modification

This is 522fireball and my jeep; and just poking fun @ the last post by brown man. My jeep before the motor rebuild, and I will have a picture when it's finished.

30's will rub off-road, but on road you should be fine.
If I remember correctly the stock tire was a 28" or a 29".

[boodlebutt]

yup stock tire is 28". at least for the 1989 year it was. 16" rims never came on the cherokee, but are stock for the grand cherokee.

31"No lift required for street use but there may be some slight plastic fender rubbing. 2" to 3" lifts are recommended for trail use to increase articulationNo lift is required but a 1" or 2" body lift can be used in place of a suspension lift to gain clearance and eliminate rubbingNo trimming is required and none is recommended
32"A 2" to 3" lift would be recommended, a 4" lift would provide greatly increased articulation without rubbingA 2" body lift combined with 1" lift extended shackles could be used to clear this size on an extreme budget.With extended shackles or small suspension lifts there may be some rubbing at the corners of the plastic fenders under extreme conditions.
33"A 4" suspension lift or spring over conversion is recommended.A 1" or 2" body lift is recommended to increase clearanceSome rubbing may occur Some trimming of the bottom trailing edge of the rear fender may be useful.
35"A 4" suspension lift or spring over conversion is necessary. Axle & brake upgrades are highly recommended as well.A 2" body lift is recommended, a 3" lift can increase clearance.With a 2" body lift trimming some fender edges as much as 1" or 2" may be needed.

I run 30-9.50R15's with stock 15x7 wheels. They work great on road, off road the rear rubs not the front. My rear leaves are well worn though.

31x10.5R15 on a rim with 4" BS will fit with trimming, but you will rub at full lock on the back side (closest to the cab) wheel well liner with the outside edge of the tire.

You could throw in a small coil spacer and a main, 1st or second leaf from an old XJ pack and be done with it. If you wheel, it would be a good idea to add some hockey pucks up front on the bump stops, and a 1" channel to extend the rear bumpstops.
