Calculated tire CPM?

[SquareOne]

Yes, I agree that it is not strictly cost per mile in black-and-white. The fuel mileage savings alone from these tires to what I previously had actually has nearly paid for them. The tires I currently have are smart way certified and have good rolling resistance numbers. I would be looking for an equivalent larger name brand tire. I’m just curious if the cost per mile with a tire that is so much more expensive can equal this cheaper tire. Again, comparing apples to apples with roughly the same rolling resistance , would be worth the much higher initial expense?

Plus, I’m wondering if they would provide a better ride being a better quality tire.
