Can i prove it - I suppose not. I'm just highly skeptical because of the "proof" that was given to me to refute what I would "assume" (a poor study and a set of random pictures of tires on different cars in uncontrolled conditions). My knowledge of tires is mostly on the race track. A tire that heats up in the center more than the shoulders will wear more on the center than the shoulders. This center heating is solved by lowering the pressure. Similarly, a tire wearing too much on the shoulders is corrected by adding more pressure. These are not some super special racing tires, they are DOT approved radials with a "R compound", otherwise the same as a street tire, just engineered to stick better at racing temperatures.
