Nope.. 235/75/15's are typically 29x9/15 or very close to that.. I got the tire just for you and the cost is right to I think.. General*Grabber AT 2
. I'd stick to the 30x9.5/15's.. They just look right on a stock TJ/LJ. 31's are nice as well but you don't really need anything more then stock tire size from what your telling me
The AT2's are a mid grade AT that handles everything you can run into on the road extremely well and are very quite. they also last a good amount of time. They won't be really good at anything offroad but the street is there home and they are happy there..
