On my YJ I run 33x12.50's...
I have a 1" body lift
1.25" shackle lift
and 2" add-a-leaf lift
that gives me 4.25" over stock...exactly!
I measured a buncha times!
My tires are too close to my fenders as is...I actually have the tires put on a day before we fired the 1" bodylift on there and I absolutley hated them...WAY too close!
If i were you I'd go with 32's
but if you go for 33's you might be urged to throw a little more lift into your jeep...that could be a good thing too (if you have the $$$)!
Hey, it's all personal preference...I like lots room....I got used to running 29x10.50's with 3.25" of lift...i liked it.
now i rub like crazy, my flares have been worn away by tire contact in the rear and the fronts are bubbled all weird from bending the actual metal flare underneath from tire contact.
TJ flares will make my set-up liveable.
I would suggest sticking with your 31's if they are still in okay condition...wait til you get more lift on there so you don't hafta buy another new set of tires then too!
If you really wanna upgrade I'd say go for 33x10.50's and do tj flares that week.
if you don't get a little more room under there you will completely total the flares if you ever take it offroad (and you'd better!
if you don't wanna add anything else but tires and just want to impress the ladies you'd be surprised how much bigger 32's look than 31's.
"Whoa, check that guy out...Those must be 32inch tires...I bet he has a big wiener!"
