I'm not a math major but I believe it computes out to just over 2 cents per mile
tire listed for $121.68 @ Revzilla when I priced it . 121.68 divided by 5509 = .022 or .02 cents + a little rounded down
Of course, that doesn't include mounting, but the mounting costs the same for every tire, no matter the brand.
Then again, all the tires I have tested Metzler (.026), Michelin (.028), and Pirelli (.028) all came out between 2 and 3 cents per mile as well.
For someone that rides like me though, the fewer mounting jobs you have to pay for in the long run (say, in 100,000 miles), the less the "tire experience" is going to cost .....which favors the tires that get the highest mileage, which for me would be the Michelin R5's. ..at least one would think
BUT
in 100,000 miles with Michelins getting 8579 miles that would require 12 mounting fees @ $60 a wheel = $ 720
at 5509 miles (if that's all I got out of the Shinkos) that would require 18 mounting fees @ $60 a wheel = $1080
a diff of $360
However, digging deeper
12 Michelins @ 242.84 = 2914.08
18 Shinkos @ 121.68 = 2190.24
the math would show 18 Shinkos cost $723.84 less than 12 Michelins
so in 100,000 miles you would save $ 363.84 by running Shinkos even though they get less miles out of them and you have to pay for more mountings than the Michelins
Can you tell I'm retired? lol
