Being the car guy on my block, lately I've been getting involved in the "how
do I get better gas mileage" discussion at neighborhood gatherings.
Besides the usual advice, we also kicked around the merit of going to a
larger, as in taller, tire to effectively raise the final drive ratio for the
longer legs.
I researched tire sizes and find that to get a perceptible mpg difference,as
in ten percent, the tire size and corresponding weight goes up tremendously.
Most of the taller tires are truck/SUV and E rated and heavy.
I'm thinking the added sprung weight and cost of the tires might neutralize
any mpg added. Plus,the Speedpo/odo would read off, too.
Yeah, I know, Duh ?
