Guys,

Below is just some *rough* math. By my calculations, *if* Enasaves are 5.0+ mpg BETTER than Quatracs, then the $'s justify Enasaves.

Here's the assumptions:

**Tire Life:** Assuming 45,000 miles on each set of 4 tires (Enasaves and Quatracs).**Cost:** Enasaves installed + taxes & fees (my area) = $773.04**Cost:** Quatracs installed + taxes & fees (my area) = $400.21**Fuel Cost:** $3 per gallon. More some places, maybe less others.

Based on all that,

The tire costs of the Enasaves plus the fuel costs for 45k miles @ $3 per gallon @ 45 mpg = $3,773.

The tire costs of the Quatracs plus the fuel costs for 45k miles @ $3 per gallon @ 40 mpg = $3,775.

The point is, I find it hard to believe that the Enasaves are 5 mpg better (average across the whole life) than the Quatracs. I would have to think the difference would be more like 2 mpg better for the Enasaves, and therefore they would NOT be worth the premium.

__AM I WRONG ABOUT THE 5 MPG DIFFERENCE__? Could the Enasaves be that much better?
