    hey guys,

    i am going to throw 2-300 pounds of sand over the axle
    what should i reduce the PSI on the tires too? 30?

    I'd air up the tires after you throw the sand in there. I had my first experience driving on ice this week, so I'm not too sure about the actual ideal PSI.

    I've been wondering the same thing. The door says 33 rear, so I'm thinking 30ish would probably do for winter.

    You could try it out at 30 and see how it goes.

    Wow...my door jam says all tires to be at 29psi. I actually run mine at 32-34psi. I might go down to 29 or less this winter (without weight in the bed).

    That's what I had read on here before I bought the truck, so I was kinda surprised when I looked and it said 30 front, 33 rear. It's a Canadian base-model 4 banger, so it might be different from the V6...

    Here's a article from Tire Rack.

    Winter Air Pressure...You Can't Just Set It...And Then Forget It


    Tires don't really carry the weight of your vehicle...the air pressure inside them does. And maintaining the correct air pressure is a requirement for good handling, traction and durability. The tire pressure recommended in your vehicle's owner's manual or on the tire information placard is a "cold" pressure, so it should be checked in the morning before you drive more than a few miles.

    The fall and early winter months are the most critical times to check your tire's inflation pressures because air is a gas which contracts as the days get shorter and the temperatures get colder.

    For every 10 degree Fahrenheit change in outside temperature, your tire's inflation pressure will change by about 1 psi (up with higher and down with lower temperatures)

    In most parts of the country the typical difference between average summer and winter temperatures is about -50 degree F. That difference results in a loss of about 5 psi, which will sacrifice tire performance and treadwear!

    If you are fortunate enough to park in an attached or heated garage you will also "lose" pressure when you leave its warmth and venture into the real world outside. So add 1 psi of "cold" tire pressure to compensate for each 10 degree temperature difference.

    And finally, don't forget to keep your valve caps on. If left off, moisture can freeze in the valve and allow the air to escape.

    Check what the recommended PSI is on the tires. The door pressure is for stock tires. Generally if your carrying any weight you want your tires to be harder. If you don't have enough air in your tires, you risk heating them to much and failure. Especially if you do much high speed (highway) driving. My tires are at 34 psi. If I were going to pack a load I would air them to 40psi.

    Mine says all 4 at 29 psi also, there are a number of posts where people say their tag says 29 front and 32 rear...is it the 4x4's that are all the same, or which trucks are the same PSI on all 4 and which are different front/rear? :confused:
