Can anyone tell me what is the largest tire I can run in stock configuration. I don't want to liftit or cut the fenders or any of that stuff.

 

id say about a 30" maybe a 31"

 

30inch will fit and not rub.

31s will fit also but will rub slightly at full lock.

 

So 265?

 

Biggest can fit with zero rubbing and no problems is a 235 which is equal to about a 28.5" tire, u might get away with a 30 depending on the condition of ur suspension.

 

Is that a 235/75R15 or a 70 profile? Easier question: what's the max width with a 29" tire, a 30" tire, and a 31" tire?

 

Well my cherokee had 31s with a 10.50 width. It rubbed but barely at full lock. I think anything under 10.50 width would be fine. Unless your backspacing is different.

 

I got 235/75-R15 on mine and at full flex with the factory suspension i have a little over a quarter inch between the tires and the flares and my wheels have a 3 inch back space. I know for a fact that a 30 would rub, or at least on mine it would and i have virtually no sag in my springs. Even with the factory wheels they would rub

 

I was thinking a 30x9.50x15 would rub with stock configuration. I'm thinking an extra inch in the suspension would clear these relatively narrow tires.

 

Using stock wheels and stock settings. 30x9.50s will work all day long. I chose 235s because the tire I wanted only came in that size.

 

I thought a three inch lift with no cutting was necessary to clear a 31x10.5x15?

 

31s will clear no problem with a 3" lift, only problem u might have is if u are using stock rims u might rub on the lca's at full turn. To fix that, spacers, new rims, or some ppl use wj or zj? Lca's.

 

235's, wow that's small. I will have to reconsidergetting one

 

you and me are on the same boat i can see a lift in my future because i dont have the money for it at the moment...

 

Every tire manufacturers mold is different by plus or minus up to one inch. So one 235 might be taller or shorter than the other.
