I have 225/75/16 (I think I remembered the #s correct, these are the standard class-c tires) Would going to the next bigger size (larger diameter) help with fuel economy?
I have been told it would since the engine running rpm would be lower, but do not have positive proof. If anyone has done this then that would be the person to respond.
Yes the engine would be turning less rpms. But it would also be making less power, and you would lose towing capacity, and your engine would be working harder when towing, actually causing MPG to decrease.
My TV gains 500lbs of towing capacity just by dropping to 17" tires. Larger/ taller, or shorter tires effectively change the rear gear ratio of the truck.
