Anyone running 35" or 37" tires with 4.10 or 4.30 gears?
I'm running 35" tires with a Donahoe Racing 4.5" lift. My truck is a F250 Lariat, 6.4, CC, SB, SRW with 3.73's. My truck feels down on power and my city and towing mileage have suffered significantly (~8 in the city and ~7 towing 8k#). I've done all my research on re-gearing to either 4.10s or 4.30's, but before pulling the trigger wanted to hear from anyone that is running a larger tire and has re-geared.
Any input on how performance and gas mileage is post re-gear?
