Hello,
I paid $6.75/gallon at Costco today. I couldn't help but think about the difference between 10 and 11 mpg.
My entire life the primary reasons to not inflate beyond the door sticker is due to inconsistent mpg improvements to justify the known expense, excessive tire wear, ride quality, and safety concerns due to idiots thinking if 5 is good 15 will be great.
I did the math on my tires and learned the following:
70,000 mile projected life.
$1294.68 installed
$0.0185 tire expenses per mile
If I intentionally destroyed my tires life by half, my tire cost per mile would be $0.037
This means with gas at $6.75 a jump from 10 to 10.58mpg would be a no impact break even point. No impact means that I would actually save $1296 in fuel within 35,000 miles. So I wouldn't have any impact to my wallet in the future, and I would save money within the first tank. If I just wanted to save half of that amount thus saving the other half by the time I would need the 2nd set, I would just need to get from 10 to 10.28mpg. If gas hits $8/gal, 10 to 10.48mpg or 10 to 10.23mpg.
What am I missing?
