Really, I agree - these two topics (how brakes work/how tires grip) are NOT related in most any way shape or form.

Tires and the road are a complex combination of factors already mentioned and are governed by car and suspension physics, material interaction between the tire and road and the tire and it's construction, and other factors that are still being discovered and developed to this day by tire engineers to improve grip. Hence new better tires are being introduced regularly.

Pad interaction with a brake rotor is also complex, but depends on VERY FEW of the same concepts and interactions as tires and the road. Coef. of friction is not simply how hard the material presses the rotor but is a complex function of the boundy interactions between coatings on the rotor and the pad that changes as temperature between them become elevated. There is no deformation, camber, caster; bottom line few of the same interactions occur as a tire/road. If it were simply a friction thing, then there would be no difference between pads, which we all know is completly not true.

A new thread about tire/road interaction is both a good idea (not here) and obviously an ever interesting topic for us all.....BUT it has very little (did I say that already) to do with this thread, if anything at all.
