This is easy so I guess I will give my understanding

  The car is capable of being propelled by a force = to four times the the
torque (traction) of the tire with the LEAST "traction"

answer hidden in the answer above, except with the center locked, least of
fronts X2 + least of rears X2
with both least of fronts X2 + both rears

However coefficients of friction for static vs kenetic would have to be
included for the most accurate answer as a locked diff can force a tire to
spin (loose traction)(as a spinning tire will be able to transmit less
torque than one on the verge of spinning.
