If load was the determining factor, there is no reason for the front tire pressure in a passenger car to be lower than the rear in "normal" payload configurations.
As far a curb weight goes, when does a manned vehicle
ever operate at that weight? (Okay, maybe it you have an near-empty fuel tank and a horse jockey for a driver.)
The majority of the passenger cars that I deal with specify higher pressure in the front tires, if there is a difference.
