That was a Toyota service tech that told me that. When I took the truck in for the dreaded 60k service he dropped the pressure to 35 psi then argued with me when I told him 35 was way too low for a tire rated for 80 max. My bet is the guy just assumed it was a 6 ply tire and never bothered to check the sidewalls then got defensive when I called him on it. What really pissed me off though was they claimed they drove the truck after service and those tires at 35 psi feel like your driving on four flats.
It pisses me off when tech's screw with my air pressure. Just had mine in for a dash rattle, and the TPMS. The first time they didn't fix the TPMS right so they got the privelage again. So far it's fixed, but they dropped the tires to 38 psi all around. Noticed this and dropped the rear to 33 and left the front at 38 til i decide to air them up. I like to run a little more in the front on my mudders, for better wear (45).

35 may not be too low for the rears when empty, but i'd never run that in the front, period. Waaaaay too low on even a 6-ply, let alone a 10.

I try to stay as far away from the stealerships as possible. The DO NOT care about your ride whatsoever.
