comparing the used up tires you just took off with the brand new tires you just put on. An unfair comparison as the tread hardness will be different new to old as well as the tread evenness and the tread depth.

The only fair test is new to new or old to old.

And pray tell how in the heck can you tell how your new tires will wear compared to the old?

Sounds to me a lot like justifying the wisdom of your purchase...in economics it is called the halo effect...it's good because I choose it.
