You're gettin' it, but quit thinking about the TIRES goddammit LOL...think of the grip between the rotor and the pads not being linear, and that at some point far short of what the tires really have to offer, the grip at the rotor/pad suddenly goes to infinite and THEN the tire locks. Bigger rotor/better pad, more grip before snapping to infinite.
