You hear about the importance of checking and adjusting your RV tire pressure, but how often are you really monitoring it? If you don’t own a tire pressure monitoring system (TPMS), having an adequate Truck and RV tire pressure gauge is essential.
Some questions to consider when using tire pressure gauges.
Is your tire pressure gauge accurate? Is the gauge you have suitable for the pressure of your RV tires? Is your tire pressure gauge adequately maintained?
You can do a few things to verify if you have any questions about your tire pressure gauge’s accuracy.
- The most accurate way is to take the gauge to a nearby tire dealer or fleet truck repair facility and ask them to verify its pressure reading using a “master gauge.” A master gauge is a gauge licensed and calibrated, to be exact.
- An easier method is to check the air pressure on a tire and then check the same tire with another gauge. If the readings (4 or more psi) vary significantly between the two gauges, either or both gauges may be inaccurate. The gauges are more than likely to be correct if both gauges read within 1 to 2 psi of one another.
Note: Don’t depend on pressure gauges at gas stations. Typically, they fall out of calibration after a few months of use.
Select a gauge specifically for Truck and RVs
Not all tire pressure gauges are created equal. Most tires for cars are inflated to about 32 psi, so a 0 to 60 psi gauge is adequate. Some motorhome and truck tires, on the other side, are inflated to 100 psi or more and need a gauge specific to those pressures. Be sure to select the right one for your needs.
Maintaining your tire pressure gauge.
Maintaining your gauge is more of practice instead of a process. Don’t let your pressure gauge live at the bottom of your toolbox or truck bed. Keep it free of water, grease, and grime. I store mine in the driver side door of my truck for easy access.

Will a tire pressure gauge completely stop blowouts? No, but it’s an inexpensive tool that can save you a lot of money in the long run if you can catch a problem early. Here are a few we recommend for your tow vehicle or RV.
Pro Tip: It’s simple advice. If you don’t have a TPMS, get a good gauge with an easy readout.
