The Complete Buying Guide to RV Tire Pressure Monitoring Systems

A flat tire can ruin a road trip. A tire blowout can do much worse.

That's why more RV owners are turning to tire pressure monitoring systems (TPMS) as an essential part of their travel setup. By continuously tracking tire pressure and temperature, a TPMS helps alert you to potential problems before they become dangerous roadside emergencies.

Whether you're towing a travel trailer or fifth wheel or driving a motorhome, proper tire pressure plays a major role in safety, handling, fuel efficiency, and tire life. The challenge is that tire issues aren't always visible until it's too late. A tire pressure monitoring system helps bridge that gap by giving you real-time visibility into what's happening at each wheel.

In this guide, we'll break down what an RV tire pressure monitoring system is, how it works, the benefits it provides, and what to look for when choosing the right TPMS for your RV.

Every RV owner knows that when it comes to RV travel, safety is top priority. One of the best ways to boost protection and performance is with an RV Tire Pressure Monitoring system (TPMS). A TPMS is a safety feature that, once installed, not only protects you from hazardous tire blowouts but also extends tire life and boosts the fuel efficiency of your rig.

With so many RV TPMS options out there, finding the right one can be overwhelming. Here, we break down the nitty gritty on why tire pressure monitoring systems are essential to RV safety, how they work, and how to pick the best one for your RV.

An RV tire pressure monitoring system (TPMS) continuously monitors your RV's tire pressure and temperature, alerting you to unsafe conditions before they become serious. It helps improve safety, extend tire life, and reduce the risk of blowouts.

An essential safety feature, a properly installed TPMS electronically tracks the air pressure in your tires, making sure proper tire pressure is maintained and alerting you when it’s not. In fact, tire pressure monitoring systems are so critical to vehicle safety and efficiency that the United States deemed them mandatory for the automotive industry in 2007.

An RV TPMS provides real-time tire pressure alerts that help you identify problems before they lead to tire failure. It's one of the most effective ways to improve towing safety and protect your RV investment.

Above all, safety is the most important reason to install an RV TPMS. Poorly inflated tires can lead to hazardous blowouts that put your life, and the life of everyone on the road, in danger. A loss in tire pressure can happen to even the most prepared RV owner. One rogue nail on the road, a drop in ambient temperature and routine wear and tear can all cause your RV tires to lose air. An RV TPMS reports real-time tire pressure information to the driver via a gauge, display or warning light. With double the tires of the average vehicle on the road, an RV TPMS is an excellent tool to prevent costly repairs to your rig and injury to those in its vicinity.

RV tire pressure monitoring systems extend tire life. It’s not just a fast leak or underinflation that you need to worry about. Overinflated tires raise cause for concern as well. Whether your tires have too much air or not enough, improperly inflated tires result in premature tread wear. Installing a TPMS ensures you get every last mile out of your RV’s (very expensive!) tires.  

Protecting the longevity of your tires is just one way RV tire pressure monitoring systems reduce your carbon footprint. Going the distance on underinflated tires has a damaging effect on your rig’s fuel economy. Even a subtle dip in tire pressure is enough to increase drag, causing your RV’s engine to burn more fuel. Maintaining perfect PSIs with an RV TPMS will maximize your fuel efficiency mile after mile.

How an RV TPMS Can Prevent Tire Blowouts

An RV TPMS helps prevent tire blowouts by warning you of low tire pressure, rapid air loss, and excessive heat before they become dangerous. Early alerts give you time to safely address the issue.

How an RV TPMS Improves Fuel Economy

Properly inflated tires create less rolling resistance, allowing your RV to operate more efficiently. An RV TPMS helps maintain correct tire pressure, which can improve fuel economy and reduce unnecessary tire wear.

How an RV TPMS Extends Tire Life

Maintaining proper tire pressure helps tires wear evenly and reduces heat buildup that can shorten their lifespan. A TPMS makes it easier to keep every tire operating within its recommended range.

An RV TPMS uses wireless sensors attached to each tire to measure pressure and temperature. The sensors send real-time data to a display or smartphone app, alerting you when a tire falls outside safe operating conditions.

In its most basic form, an RV TPMS uses external sensors installed on each tire’s valve stem to provide constant monitoring of tire pressure. As soon as a drop in tire pressure is detected, the information is relayed to a device installed on your dashboard or, in some cases, to an app on your smartphone. However, not all TPMSes are created equal. Some systems also monitor the temperature of your tire — a key indicator of tire performance — along with a host of other features that vary by manufacturer.

RV tire pressure monitoring systems come in two types:

A direct RV TPMS measures the actual air pressure inside each tire using dedicated sensors. It delivers accurate, real-time readings, and immediate alerts when pressure or temperature changes.

A direct RV tire pressure monitoring system uses pressure monitoring sensors mounted within tires that wirelessly transmit data to a centralized control module for interpretation. If high or low pressure is detected, it transmits a warning directly to a dashboard-mounted device or smartphone app.

Direct TPMSes provide the fastest, most accurate tire pressure readings of the two options. However, they also come with a higher price tag and a more involved installation process.  

An indirect RV TPMS estimates tire pressure by monitoring wheel speed through the vehicle's ABS rather than measuring air pressure directly. It is generally less accurate than a direct TPMS.

Indirect RV tire pressure monitoring systems work in an entirely different way. This model estimates tire pressure through already installed sensors that monitor tire rotational speeds. When a wheel starts spinning faster than expected, the computer signals that the tire is underinflated and alerts the driver.

While much less accurate and complete, indirect RV TPMSes are more helpful than no monitoring device at all. If you want something easy and inexpensive, an indirect system might be for you.

The best RV TPMS accurately monitors every tire on your RV, provides instant alerts, and is easy to install and use. Look for features like temperature monitoring, expandable sensor capacity, and smartphone connectivity.

There’s a huge variety of TPMSes on the market. From the most basic monochromatic monitors to smartphone app integrations, here’s a breakdown of the features you’ll want to look for when shopping for your own RV tire pressure monitoring system.

Consider monochromatic vs. full color. While black and white displays have a lower power draw, colored LCD display monitors are easier to read with a quick glance. Whatever you decide, a display with clear, readable alerts is crucial.

The best TPMS can measure both high and low air pressure, monitor temperature, report on slow leak detection and faulty sensors and indicate when your battery is getting low.

You should purchase a TPMS that can support the number of tires on your vehicle. Some systems like Tire Linc® can monitor up to 20 tires at a time.

A 12V repeater signal is key to boosting the signal sent by the sensors. This provides the most up-to-date information regardless of where you are.

Tire pressure monitoring systems that feature iOS and Android compatible app integrations take your RV safety to the next level. Apps like OneControl® by Lippert allow you to manage your sensors, set tire pressure ranges, get notifications and view alerts, all from your smart device.

This is especially important if you plan to install the system on your own. Manufacturer instructions and tech support provide great resources when DIYing your TPMS install. If your RV is newer, it may be prepped for the Tire Linc system. For these models, simply place the repeater in the preinstalled docking station and you’re ready to go.
