I differential works when opisite tires on an axle turn at different rates (ie. turning a corner the outside tire turns faster then the inside tire). a posi rear end locks up when one tire increases speed suddenly while to other is stationary or turning very slow. If your tires are different sizes from side to side then the differential gears ( spider gears) are turning all the time and will burn up as they are not desined to turn all the time and at high speeds. If you have smaller times then the diff wil lock up sooner and if they are much larger then factory it may not lock up soon enough.

Rear axle ratio ford crown Victoria police?
"There are two options that were installed. One and most likely yours, a 3.27 non locking diff (not posi) and the other was a 3.55 with locking diff (posi). Easy way to tell. Punch it if one tire spins it the 3.27 and if both spin it's the 3.55." That's not really true. The 3.27 was available in both posi and open diff. Nearly all P71 models have the posi unit, and a huge majority of them have the 3.27. Best way to test whether it's posi.... jack the rear end up and put the tranny in neutral. Spin one tire. If the opposite tire spins in the same direction, it's posi. If it spins in the opposite, it's open. 3.27 vs 3.55 would just be a matter of calculating engine RPM vs road speed.
