The 51psi max is the maximum pressure for the tire under maximum load. Tire pressure is increased with load to reduce heat build up in the side wall due to tire flex. To operate the tire at max load you would have to carry about 2500 pounds in the poor Z, or be running continuously at 180 mph, neither of which is possible
The manufacturer's tire pressure recommendation on the other hand is an every day tire pressure for the tire operating at average loads with average speeds (highway speeds), this is the one that you want to follow.
