"Rolling Contact Friction" is the same concept as "Static Friction", since both are the friction between two surfaces in contact with each other and not in motion relative to one another.
Maximum Effective Drive Thrust = Maximum Friction (Traction). They cannot be solved at different times, they are solved simultaneously, in Newton's Third.
If your robot's thrust is less than the available friction, it is possibly inefficient (slow to accelerate), or is ineffective (run into a wall, and it'll stall). If your robot has more force with which to push than the maximum available friction, then any acceleration > mu*Fn/mass could spin your wheels (burning carpet?).
Uncanny how much Ike Newton knew about robots !
