[QUOTE="Hawaiian Time, post: 1337955, member: 19480"] Aloha, I meant to respond to the original tire MPG question but got side tracked on some of the Troll / H8R posts. I replaced my stock KO2 335x70xR17 KO2's with Firestone Destination MT2 Mud Tires size 35x12.5xR17 on my 2017 Raptor SCREW. On the Stock tires I was getting 14 to 15 City, 18 to 19 Hwy. With the mud tires I'm getting only 12 to 13mpg City and 16 to 19mpg Hwy. Bigger tires can lower MPG in several ways: 1. More aggressive tread pattern = more rolling resistence. 2. Taller tires will raise your effective axle gear ratio from 4.10 to maybe 4.0 or 3.9 or.... The taller the tire, the bigger the change. This will increase power (lower mpg) needed to start off the line and for hill climbs. But it can actually improve Hwy mpg if not eaten up by the other factors. 3. Wider larger tires have more wind resistence. 4. Heavier tires will take more power to accelerate mostly lowering City MPG. 5. Stickier Tread Compound = more rolling resistence that will lower both City and Hwy MPG. All of the above are cummulative that combined can lower your City MPG by 2 to 4 mpg City and 1 to 3 mpg Hwy on an otherwise stock Gen2 Raptor. HT [/QUOTE]
