Have a 23 with Hemi and 3.21 rear. I want to upgrade to 275/60/20 tires that weigh about 10lbs more than the 275/55/20 OEM Bridgestones. OEM's weigh 38lbs and the General AT's I want are 48-49. Anyone made a similar move? I would purchase the alpa device to corrected the tire size. How much of a MPG hit? What about performance? I have when trucks search for gears running down the highway at 70+. Came from a 17' with the Ecodiesel and ran 275/60/20 Ridge Grapplers (47lbs) with minimal issue. Ram went with a smaller tire on the 5th Gen. Maybe I should stay with OEM size?
