i am buying a new tires today. my tires size is 235/65R17 will 265/65R17 fit my car ( grand cherokee limited 2001 )

 

your stock tires now work out to about 31x9.25x17
your new tires would work out to about 33x10.5x17

they may work, but i think you will run into some rubbing.
nothing a 2 inch budget boost won't take care of tho.

edit: i was going on 75's, so,

your stock tires now are about 29x9.25x17
new tires would be about 31x10.5x17

but still may rub.

 

you might have to do a 2" bb.
