I'm a brand new 5th wheel puller and am trying to figure out the best combination of rim height, tire profile, rear end gears that will give maximum fuel economy for some 65mph highway pulling. My truck is a '95 Silverado 3500 dually with 6.5 diesel. I like the low profile of the 75 series tires but was told that will rev my engine more than I may like. Anybody with some real life experience?
