While the conventional equation for friction is only a first order
empirical
formula, how much deviation is there for racing tires? Actually some
racers
do have a scientific background, and use it in their designs. The
answer
that was given does not give much in the way of clues. As the
goescontact/area
down one would expect that the number of atoms in intimate
also
goes down, which makes the classical formula make sense.
