I was thinking that a good way to increase your FE in that jeep is to get class d tires i think they Are because there able to hit 80 psi and i figured that with LRR tires all they've done is increased tire pressures, i mean think about it this way my jeep is 5300 pounds ok 2750 in front 2550 in the back if you take though's and divide them by 2 and then your tire pressure it gives you square inches that your tire is on then you divide by tire width and you have inches from front to back and the higher the pressure the less tire contacting the road and less RR.

there you happy now Frank
