With 4.10 gears you won't notice any change. Bet the bigger tire.

My 315's are less than 34". But they are getting close to needing to be replaced (about 6 mos. ago)

I just ordered some 285/70/17's and I believe that they are 33" OD according to BFGoodrich Tires | Mud-Terrain? T/A® KM2 | Tire Sizes & Specs

check out the size/spec tab.
