How To Find the Correct Tire Pressure For Your Truck

by GuestPoster on March 11, 2012

Having the correct tire pressure is very important for getting good fuel mileage out of your truck and tread life out of your tires. Tires that are underinflated will wear out quicker due to increased friction between the tires and the road. Tires that are over-inflated can produce an ill-handling truck and a bouncy ride. The incorrect tire pressure can also affect the way your vehicle responds in an emergency situation.

The correct tire pressure for the truck can vary significantly depending on a number of factors. The average pressure in a truck tire can range from 30 to 100 psi. It can vary depending on whether the vehicle is a light truck or a heavy duty truck, the model of the truck, the load that it carries and the speed and conditions in which it travels in.

Many truck tires nowadays come with pressure sensors that can monitor the pressure inside the tires and send a warning to the driver if the tires lose significant pressure. For accurate readings it is always a good idea to test your truck tires manually every once in a while using a truck tire pressure gauge. Tire pressure gauges enable you to determine the air pressure inside a pressurized tire by attaching one end of the gauge to the stem vent of the tire. The gauge will then provide an air reading in psi. Psi stands for pounds per square inch and should correspond with the recommended tire pressure of the vehicle. This can be found either in the inside of the door or in the user’s manual.

While most tire pressure gauges are made for cars and smaller vehicles, truck tire pressure gauges are available for heavy duty truck tires. These tire pressure gauges often have a higher psi range as heavy duty truck tires require a much higher pressure inside the tire due to the heavier load they carry. When buying a tire pressure gauge for a heavy duty truck the maximum psi range should be at least 100. For large truck tires make sure the pressure gauge comes with a flexible hose for deep set tires – this is the part that connects to the tire’s stem vent.

Always check the tires pressure when the tires are cold as warm tires can alter the pressure inside the tires. It is best to leave your tires to cool for a few hours before taking a reading.

Do not inflate your tires to the pressure listed on the tire sidewall. That number is the maximum pressure the tire can hold and not the recommended pressure. Over-inflating the tires can be dangerous both for the person inflating the tire and while driving the vehicle.
