The original question is about slip, not acceleration (although I know the former brings the later, so...).

I think everyone is messing all up with this.
Power and torque being in the same lineal ecuation and cars having gears, who gives a damn about one or the other?
A tyre, like everyting else in this world is a mass-spring-damper system. Or a combination of several of those systems if you will. Well, the longitudinal "slip" component of the M-S-D in the middle between rim and the ground has coefficients in its ecuation that can describe friction characteristics. The whole system, like any other M-S-D one, is sensible to speed and acceleration.
