    I can't remember what my current tires run.
    But I run whatever is specified on the tire itself.
    If you buy aftermarket wheels/tires and go to a different size, etc., chances are that specific tire/manufacturer designed their tire to run at a different pressure.
    Particularly if you go up to a 10-ply for towing.
    So, can't really go by what's in the door jamb.

    I always fill to just below the max cold-fill pressure specified on the tire for better fuel economy. It's almost 10 psi higher than what the sticker in the door jamb suggests for P-rated tires. When filled to the lower Toyota recommended pressure the truck feels a bit sloppy and sluggish to me.

    E-rated tires will vary much more, like RRzxter touched on. The guys who do a lot of towing can comment on high ply tires.

    What size tires?
    What load range?
    Conventional or synthetic air?
    Are you running summer air or all-season?

    CrewMax - scaled weight of 6,050 lbs with just me and a 1/2 tank of gas. Tires: 285x75x18 Toyo Open Country M/T's: Unloaded 30-32 psi, anything higher starts wearing out the center first. Towing our 26' travel trailer: 40 psi. This is my 3rd set of the Toyo's on two different Tundra's. The lower psi gives me a more even wear pattern. I'm averaging ~50,000 miles per set. The other key to long tire life is to rotate and balance! I have it done every 3,000 miles since it's "free" for me and was included in the price of the tires. Doing it today after work as a matter of fact. Especially important on the larger M/T type of tires.

    I have the stock tires and run the maximum pressure printed on the side wall. The harder the tire the better it rolls. I am not concerned about a cushy ride.

    I use 30psi up front and 32 in the rear... I think that's what toyota recommends.

    How come some of you guys put over 40psi? Isn't that bad for the mpg?

    Not everyone is using the same tire. Did you read all the posts?

    I recently intalled Michelin LTX AT2 E-rate 10-ply tires on the factory 20" wheels. I had passenger rated P-Metric equivalents on previously. With ~60K miles, I had excessive shoulder wear and good tread left in the center of the tire. I rotated and balanced frequently. With 32 PSI, I had excessive sidewall flex so I generally ran these tires at 38PSI. With the tread wear pattern, I'm curious why I had shoulder wear that didn't match the tire's center. Give the high PSI, I expected the tire to be more donut shaped and wear in the center more then the shoulder

    I'm curious what I should ran these new E-rated tires at. I think I will try 40PSI.

    On a related note, these tires really kill the ride quality. With the P-Metrics, my Tundra had almost a car like ride on most road surfaces. The jury is still out on the E-rate equivalents but, they are a much rougher ride though things are smoothing out with a little bit of break in.
