Default Re: H3 MPG < H2 MPG
IMO two things may be at play here, first is the diameter difference in tires, since w/315/75/16 you are going 3.5 mph faster than w/285/75/16 therefore farther distance traveled with each revolution your odo is not showing true distance making your mpg caculations off (to my knowledge no one recalibrates speedo for h3 as of this time) second when you went to 35's did you also go M/T I was getting about 17.5mpg on highway w/stock 33's, changed to 33 in bfg mt and dropped to 14.85 mpg on highway(higher resistance tire = worse mpg)
