Frequently Asked Questions

Do aftermarket tire pressure monitors actually work?
Yes, we've found that aftermarket systems can be incredibly reliable. For our long hauls, we rely on units like the TST 507, which has consistently provided accurate readings for over 50,000 miles without a hiccup. It's crucial to choose a reputable brand; we've seen cheaper options give false alarms, which is never ideal out on the road.
Internal vs. external TPMS sensors – which is the better choice for my rig?
For most of us road-trippers, external sensors are the way to go. They screw onto your valve stems, making installation a breeze and battery changes simple when the time comes. Internal sensors are cleaner looking and protected inside the wheel, but they require tire dismounting for any maintenance, which is a hassle we try to avoid.
How accurate are these tire pressure sensors?
We've tested several direct-monitoring systems, and most provide readings within 1-2 PSI of our trusted digital tire gauge. For example, our TST sensors consistently show pressures that align closely with manual checks, giving us confidence in the data. It's important to remember that tire pressure fluctuates with temperature, so monitor readings are always best taken when tires are cold.
Can I install one of these tire pressure monitoring systems myself?
Absolutely. Most external sensor systems are designed for DIY installation; you simply screw them onto your valve stems. If you opt for internal sensors, that's a job best left to a tire shop, as it involves removing the tire from the rim. We generally stick with external for ease of use.
Do the sensors on these tire pressure systems need batteries?
Yes, the sensors themselves typically use small, replaceable coin cell batteries, often CR1632 or similar. We've found that good quality sensors, like those from TST or TireMinder, can have batteries that last for several years - sometimes 5 years or more, as we experienced on RV forums. Replacing them is usually straightforward with external sensors.
