Comments on: How to INCREASE your gas mileage, and save money on gas.

on 8/12/2008 Great Tips!

on 8/8/2008 I'm glad you changed your math to the correct formula instead of that wishful muse of over $1600 dollars. By the way, unless you need new tires, it would be pointless to buy new tires just for that savings. Also, be sure to consider that you can only get "Taller Tires" for this theory to work and not "Wider" tires since that would increase road friction and put you right back where you started. I can't believe I'm going to say this, but the tire argument is really best settled by keeping your tires inflated to the correct "POLITICAL" pressure.

on 8/5/2008 Wait a minute Mr Math..... Your equation is way off!!!
Just because you can go an extra 9 miles per TANK of gas, does not mean you are saving 26 TANKS of gas per year! You assume you have driven an additional 468 miles in savings with larger tires/year. Now divide that number by the miles per gallon your car/truck gets and then multiply by price per gallon of gas. Example:
car gets 15 miles/gallon... saved 31.2 gallons x $4.00/GALLON ACTUAL SAVINGS WOULD BE $124.80.

Sorry to deflate your savings...

on 7/27/2008 Hold it a minute. Changing to a higher profile tire is like going to a higher gear. The engine works at a lower rpm for any speed.
SOMETIMES the higher gearing will help gas mileage, like going downhill or maybe on a flat.
BUT, sometimes the rpm will be too low, like trying to climb a hill on a bike in too high a gear.
You get tired faster because you're not as efficient.
Your engine has an rpm band that is more efficient, and it needs to stay there. If a new tire size puts it there, fine.
If a new tire size moves it from the band, so sorry, Charlie.
