    Evening Tundra Fam, needing some tire expertise please. 2015 Tundra Crewmax 5.7

    Toyo AT3s P285/55R20 114T (2,601 lbs max 44 psi)

    What PSI should I be running? I keep getting different answers from shops. Online conversion calculation saying 36 psi max, which looks a bit too low... Toyo saying 45 psi.

    Original tires were Toyo Terra Grappler LT285/55R20 at 49 psi.

    I've included door sticker for reference.

    Any guidance would greatly be appreciate, thank you!

    somewhere between 30 and 44(max psi)

    chalk test will be best. otherwise it's just a guess with all the variables of your truck and load
