Hoosier A7 tire question

From a Grassroots article below. Are Hosier A7s made the same way with a tread base rubber? Thanks.

GRM: Why doesn’t a worn tire equal a race slick?
Maxxis: A worn street tire probably has thousands of heat cycles by the time it is worn down to a slick. Therefore, the compound probably doesn’t have much dry traction performance left due to thermal and oxidation aging.

Also, some street tires feature something called tread base rubber. This is the layer of the tire that binds the actual tread to the cords and other inner components. So, when the tires are worn down to a slick, you may be driving on this tread base rubber, which has almost no dry traction properties.
