Maintaining the proper air pressure in your RV’s tires is essential, as it is for your tow or towed vehicle. There are lots of cheap tire gauges out there, but do yourself a favor and invest in a good-quality gauge.Dual foot tire gauges have a special foot that makes it easier to access different types of valve stems, including those on dual wheels without valve extenders. Dual foot tire gauges are designed for the trucking industry, so they are calibrated to much higher PSI ratings than automotive ones and tend to be much more accurate.
Have an electronic Tire Pressure Monitoring System or TPMS? You still need one of these. If one of the sensors is giving wacky readings, you need a good gauge to confirm whether it’s right or not!
There’s a good selection of these gauges at Amazon, Camping World, or at your local Pilot Flying J. They’re in the tool section with all the big rig stuff!
