Re: Will taller tires give better mpg?

You might want to go and change out all your old fluids and replace them with synthetic. Check your air filter and brakes. A good wash and wax will help with wind resistance. And make sure your air pressures are up to normal. Get some guages. Get a chip from Jody at DP-Tuner
and maybe a couple postions for stock, towing, and fuel economy. As long as you keep your foot out of the pedal the custom tuning of the chip will net you more MPG than trying to cheat your way with an empty load on larger tires than hurting the mileage while towing. </div></div>
Thank you everyone for all of the great information about MPG related to tire size. I'm still undecided about what to do with the tire size, since some people found an improvement in mileage with increased tire size, and some people thought that it wouldn't help or would be worse.
I guess I will keep the tires as they are for now.
Thanks, PwrStrokinDually, for the suggestion that synthetics would help with MPG. That is certainly an easy thing to do; so I will start there and see how much that helps. Which synthetics would give me the best MPG?
