i got a 3" lift with 31s right now. the front ones are bald so i need new ones before winter. I could just get 2 31s and save some money, but i kinda want bigger tires. 32's maybe 33s. i was looking at the 33s and noticed i could get them 10.5 which my 31s are and 12.5. think i would need a bigger rim? how big can i go before i gotta re gear or axel swap i think i should be alright with 33s. give me some input

 

meh its whatever you want to do. Plenty of info on this subject in the search button

 

shouldnt need to regear or change axles for 33s. I'd suggest doing that and trim your fenders. 3.5" lift and 33s is my fav.

 

if you have the D35, 33's would be scary. If you have the 8.25, you'll be good. I would regear at 33's but thats just me.

 

You will be completely fine with the 33's on the D35. I run 35" Mud Grapplers on a D35 and off-road/DD the **** out of mine with no problem. I'm not sure if you have trimmed the fenders yet on your XJ yet, but with the amount of lift you have your going to have to if you want to fit 33's. Also, you can fit 12.5 on the stock rim.

 

little spacer in the front, little block in the back, then get 33's.

 

He mayyyyy need new longer control arms if he puts a spacer in the front.

 

Ideally, 1"spacer front, 1" longer shackle in back with shims, a TC drop or an SYE, and minor trimming of wells... Or leave it where it is and chop the heck outta the wells to stuff the 33s. If you disconnect the front sway, you'll need to chop more. Longer lower LCAs might help for wheelwell centering since with stock arms those 33s will wanna dig in to the back..

Avoid blocks unless you like axle wrap IMHO.

 

ya i do got the 8.25. just want to get some opinions before i spend all that money

 

I would regear for 33's, not for 32's. 32's where tolerable for me, 33's it was a dog. But to each there own.

Don't put a block in the back. plenty of options, blocks suck. for 1 inch, longer shackle or relocation brackets are the best 2 options IMHO.

Pick the tire that will be better for you, then deal with whats needed to make it work. making 32's fit when you want 33's sucks as you will still want the 33....

 

15 x 8 wheels are fine for 12.50 tires

15 x 7 are fine for 10.50 tires its a toss up between the 2 for 11.50 tires, the 8'' being the better option.

with 33's youll lose response and mpg, but gain ground clearence, while sacraficing flex.

 

I have been running a D35 open with 33's for a while now. It is only scary if you are if you are locked stock shafts beating the hell out of it.

running 15x7 ranger rims with 33x12.50 bias swampers and have had 285/75R16s on 16x7 for a couple of years now.

some photos for the OP

lift specs: 5" front consisting of 3" coils and 2" spacers teraflex arms RC tracbar, rear is just 3" bastard pack.

 

My friends YJ runs 38.5 on a dana 35 locked no problems for years now

 

I went through the same thing. I had bald 31s on my jeep that had a 3" lift. I bought brand new 32s and they rubed so I lifted
My jeep up 2 more inches

 

It all depends how much you want to trim to fit the bigger tires. I know somone that had 35s on just a 3" lift and it never rubbed on the trail and full flex. Also didn't have a front or rear sway bar
