i just bought BFG 31 inch mud terrains and i had 33 goodyear mtr originally, it was okay around town but once i hit the freeway on overdrive it would bog down horribly, made my truck just slow. as far as i know i have stock gearing but i decided to downsize the tires to save the life on my 3.0 and get better mileage....so what is everyone else running?

 

33s on my 3.0 but i dont use OD unless im on the interstate with a good straight stretch. I deff lost some ump since switchin from 31s but im regearing with 4:10s in the front and an exploder rear with 4:10s to recomp for some power an hopefully gas.

 

34's lost power i have 3:88 gears(stock)and mileage sucks about to put 31's back on till the gear swap is done to 4:10's
