What PSI Should My Semi Truck Tires Be?

When it comes to semi truck tires, maintaining the proper tire pressure is essential to ensure safety, improve fuel economy, and reduce the risk of a blowout. As such, it’s important to know what PSI your truck tires should be.

The majority of modern semi trucks are outfitted with dual rear axles, which means there is a pair of tires on each side. The optimal PSI for these tires varies depending on the make and model of your truck. Check your owner’s manual for this information as it should list the ideal pressure for your particular vehicle.

In general, most semi trucks use a tire pressure of between 80-100 PSI on each dual axle tire. The exact pressure will depend on the load being carried as well as any special instructions from the manufacturer. It is important to note that if you are carrying a load heavier than normal, you should increase the pressure accordingly in order to maintain optimal performance and handling.

It is also important to monitor your tire pressure regularly and adjust it accordingly as needed. If you notice that the pressure in one or both tires is too low or too high, make sure to adjust it until it reaches its recommended level. You can use an air compressor or a specialized gauge designed specifically for semi trucks in order to achieve this goal quickly and easily.

In conclusion, when it comes to what PSI your semi truck tires should be, it is best to consult your owner’s manual for more specific information regarding your particular vehicle. In general, most dual axle tires require a PSI between 80-100 depending on load weight and manufacturer specifications. It is also important to monitor tire pressure regularly in order to maintain optimal performance and safety.
