On my dad's Toyota Camry, it lists two sets of tire pressures. One is for "up to 4 passengers" 26psi all tires. And the other is "up to the load of the vehicle" 29psi all tires. On the other hand the VW Jetta list for half load 26psi all tires and for full load 30psi front 40psi rear. I think on the newer VWs they only put the full load pressures. So would it be a good idea to use the full pressures. I find that 26psi in all tires would be a bit low considering the 44psi max tires. Also is it true that newer cars now only list one set of pressures(full load) and don't put half load anymore? Currently I run 30psi on the Camry tires since it gets loaded often. On the VW I run 26psi since that car rarely gets loaded.
