How Much Of A Difference In Rpm's Will I Notice While At Hwy Speeds If I Go From 35" To 37" Tire. With 456's And 35's I Am Running Around 2700 Or 2800 Rpm At 65. Not Exact Since My Speedo Is Off, But I Would Like To Drop To Under 2500 Rpms If Possible. I Dont Want To Swap Gears Or Tranny Just Tires.
