i have a stock 98 XJ, i want to know what is the max tire i can fit on it stock? i have 16 inch rims will 255/75 be to big? i dont mind a little rubbing, because most of the off roading i do is on sand not crazy trails. i also plan on getting a 2 inch spacer lift ASAP. any help would be great

With MINOR triming you can fit 31's or whatever they are on a 16inch rim...

my 31s rub at full lock on a 2" lift. this weekend i will finish my 5" though so no more rubbing

Input a tire size the calculator will display the diameter, you can also compare two different sizes.

A 31" tire on a 16" wheel is still a 31"!!! lol I'd recommend going with 15" rims asap, cause you'll find more often than not the tires will be cheaper! never understood why more rubber means less money, but what eve...

I have a stock 96 XJ and just put 245/75R16's on Rubicon Moab rims. The rear rubs a tiny bit with passengers. They also rub in the front at about 3/4 turn, then goes away at full lock. Wheeling it would not be a good thing with these tires at stock lift imo. Plus you have over a half inch of height than mine w/ the 255's. I'm also installing a 2" budget add a leaf kit for now, but will get a 3 1/2" spring pack kit in a couple of months when I can afford to do it right. Hope this helps!

255 x .75 x 2 / 25.4 + 16 = 31"

TireRack.com doesn't show a 255/75/16 tire being available. They show only one 255/75/15.

A 265/75R16 is the closest one that I can think of. If I remember right it measures out to 30.6 or some in that area.

255/75R16's are 10.03" wide x 31.05" over all (tall)

wow lol i totally was wrong in the head line! i am looking for tires to fit my 98 stock ZJ not XJ! is there a big dif in ground clearance or are they close to the same? i do have some 15 inch rims that are off of my 88 XJ will they fit the ZJ? i am swaping motors so the axles and lug pat. should be the same.

The 15s will fit. Bolt pattern is the same. Stock tire size on the 16" wheels the ZJs come with are 225-70/16. I own one and personaly at stock height I don't think a 255-75/16 will fit without rubbing. I know with a 2" BB you can fit 265-70/16s (measures out to be a 30.6" tire) with some trimming to the front bumper cover and also cutting and bending the pinch seam over in the front wheel wells.

I have a 2.5" BB with a set of Up Country Springs and I am sitting at about 3.5-4" of lift. I am saving up for a set of 265/75-16s. They fit with minor rub on front bumper but that will be taken care of when I build a bumper this summer. 265/75R16 tire is 31.6".

As far as axles being the same, if you have the V8 ZJ they are not the same rear axle. It will be the D44a. Aluminum housing dana 44.

cool man, so if i put the 15 inch rims on it do u think i can clear 31 10.5 with the 2" spacer lift? like i said i dont mind a little rubbing while turning i will mostly br riding on the beach. also both jeep have the 4.0 motor so the axles should be the same! where can i get a 2.5 bb? i havent been able to find one that high just 2"?

With a 2" spacer kit they will fit with a little rubbing. Mainly the areas I stated.

That is the kit I am running but I kept my stock coil spring Isolators on to give me about 1/2" more lift. On top of that I replaced my springs with a set of factory Up Country Springs to give me about another inch or so of lift. In total I have right around 3.5-4" of lift.
