So i have a 96' 2-dr cherokee with a 4.5in lift...im currently running a set of swamper TSL 32x10.50x15s on offset rims and dont have a problem. I was wondering how hard it would be to manage a set of 33x13.50 or even a 34x10.50 LTBs since the LTB is so narrow. any suggestions are welcome

 

cutting the fenders always helps

 

i've got a 4.5in lift as well and im running 35 in destination mt's. with a little bit of fender cutting

 

what about the 12.50 will it rub the frame when turning?

 

Flex it & take measurements, see if you have room to grow. I run 33x10.5 with 3.5 lift & what I think is OEM backspacing. I got TSL's & bubbled a sidewall, my next set will probably be the 34x10.5 LTB. My tires do rub the control arm & rear inner fender tiny bit, but no problems. With the right backspacing & cut fenders, I think you could run the 13.5,s.

 

The 33x13.50s will require some work to get them to fit. They are a really wide tire.
Go to the http://www.intercotire.com/tires.php?id=7&g=1 and check out the specs.
They have a CS of 13.00 inches, so a 10 inch rim would be the way to go.

Oh, t-newell almost all rims have offset, it is how much offset, or better yet backspacing
that matters, since offset can be positive or negative.
