Everyone probably knows this, but just in case... The tire pressure should not be set at what is printed on the tire, use the pressure listed on the tire information label in the glove box or the door post. The pressure on the tire is the maximum in order to get the weight rating capacity for the
tire.
The
truck maker takes into account the weight of the truck, etc. and specifies a recommended pressure for a fully loaded truck.
Also, the lower the pressure, the larger the tire contact patch (in general terms) but the greater the risk of over heating. Don't you guys watch Nascar??
