Well, I am not so sure where you guys get your information from.
On my fuel filler door it syas:
" FOR MAXIMUM LOADS " !!!!!!
Front: 28 psi Rear 32 psi COLD.
" FOR SUSTAINED HIGH SPEEDS ( over 100 mph ) increase cold pressure + 4 psi.
When in doubt, run slightly higher, rather than too low a pressure.
P.S. If you are " seeking the truth ", I would suggest asking the reals experts at The Tire Rack.
