i have a 1994 jeep grand cherokee with a 2inch lift. im not sure what size of tire i can fit in there. im thinking a 31inch but not sure. i like wide tires as well so maybe a 31x10.5 maybe.
any suggestions
thanks

 

That size tyre should fit even without the lift.

 

If I remember correctly your Jeep came stock with 15" wheels or have you changed them?
31x10.5 may be a bit to big on 2". Also you would probably have to get some spacers on there so the tires don't rub on the suspension.
Talk to a good tire shop and they should be able to tell you how much backspacing you'll need to run them.

 

Trust me they'll rub, i've got 31x10.5 on a stock 93 GC and they rub the rear fender well on the inside... spacers are needed to clear the suspension bits
it might ride down the road without rubbing, but start flexing the suspension and it'll rub like crazy

or get different rims that have different backspacing.
