I have a X modal JK. I recently put slightly bigger tires (265/75/16s) and it is abit slugish. Can't go up the smallest hills on the Highway and it hard to keep it at 70. I have 3.21s now. Would a chip of some kind be the answer or gears. If gears are the answer would 3.75s do or would I be better off with 4.10s.Thanks

 

GEARS ARE YOUR BEST BET. 3.73 WOULD WORK FOR THAT SIZE TIRE, BUT IF YOU CAN GET THE 4.10'S IT WOULD BE MUCH BETTER. IF YOU ARE GOING TO GO BIGGER THEN LOOK AT 4.88 AND 5.13 FOR 35'S.

I HAD 3.73 WITH 33 AND WASNT BAD. 4.10 WOULD HAVE BEEN BETTER. i NOW HAVE 35 AND 5.13' GOOD COMBO.

GOOD LUCK

 

Gears 4.10 or lower
