Fuel Economy Series Part 3 1/2

by Tim Joseph

Last night after I posted my Part 3 article I got to thinking... How did they calculate my savings? I did some research and came up with a set of equations that yield the same results. I'm pretty excited.

To calculate your tire savings:
Cost of a set of tires / 4 = tire savings

To calculate you fuel savings:
((miles per year / mpg) x average cost per gallon of gas) x 0.07111 = fuel savings

Total savings:
tire savings + fuel savings = total

This is very quick and simple but could save you hundreds of dollars per year.

My example is: 15,000 miles per year, 32 mpg, $4/gallon average, 300 for a set of tires.
My tire savings is $75
My gas savings is $133.33
My total savings is $208.33 per year

I think $3.75 per tire is more than worth that kind of savings.

Also, remember, if you're in need of an oil change soon (and who isn't), we're offering the following special:
The Fuel Saver Special - 27 point safety inspection, oil change, nitrogen inflation in all four tires for $29.95.

Since most oil changes will cost you about $30, its like getting your nitrogen free!
