Keeping tabs on your tires is easy with this TPMS kit. The compact cap sensors install in seconds and deliver real-time pressure and temperature updates, helping you catch problems early and travel with more confidence wherever the road takes you.


Highlights

  • Spot Tire Trouble While You Drive: Monitor lets you see real-time pressure and temperature updates flag pressure drops and overheating during travel.
  • Fit Rubber or Metal Valve Stems: Rubber and metal valve-stem support reduces setup friction on RVs, trailers, and haulers.
  • Cover High-Pressure Trailer Tires: 1 - 218 PSI monitoring range covers lighter trailers and higher-pressure hauling setups.
  • Help Secure Sensors on the Road: Anti-theft locking screws help keep sensors in place during travel.
  • Keep Pairing After Battery Swaps: Paired settings stay saved when you replace batteries, avoiding reset work later.
  • Expand Beyond Four Tires: Add additional cap tire sensors (RT46ZR - sold separately) for more coverage.

Features to know about

Catch Tire Trouble Before It Gets Expensive

roadtech set up with alerts

When your trailer tires are behind you for hours, a pressure drop or heat issue can start long before anything feels wrong from the driver's seat. This TPMS watches pressure and temperature as you travel and sends warnings for pressure drops, overheating, and other tire issues through the wireless monitor. Your tires stay visible from the cab, and small changes are easier to act on while the trip is still moving.

Cap Sensors That Go on Fast

When you're getting ready for a trip, tire monitoring is one more thing on the checklist. These compact cap-style sensors screw onto your valve stems in seconds without tools and sit low on the wheel with a look similar to a standard valve cap. Once paired with the RoadTech monitor, your trailer starts reporting pressure and temperature readings while you travel.

Fits the Valve Stems You're Already Running

Valve stems can be one of the annoying parts of adding external sensors, especially when your trailer or RV setup isn't all the same. These cap sensors work with both rubber and metal valve stems, which removes a major fit concern before installation starts. Your monitoring setup can go onto the stems already on the wheel, making the first install and future tire service easier to plan.

Wide Pressure Coverage for Mixed Hauling Setups

Not every trailer runs the same tire pressure, and higher-pressure hauling setups can rule out systems with a narrower sensor range. These sensors monitor from 1 to 218 PSI, giving the kit room to cover lighter trailer pressures and higher-pressure applications with the same cap-style design. Your pressure targets stay inside the system's working range, so the monitor can keep reporting readings instead of leaving part of the setup uncovered.

Battery Changes Without Starting From Scratch

easy battery swap

Seasonal storage and infrequent trips make sensor batteries part of ownership, not something to ignore until departure day. Each sensor uses a replaceable CR2032 battery with a 12 to 18 month lifespan, and the system retains paired settings after battery replacement. When your sensors need service, you can swap batteries and keep the existing tire assignments in place, which makes getting ready for the next trip less of a reset.

Video Transcript for Review of RoadTech TPMS Sensor - Cap Sensor TPMS RV Trailer - RT66ZR

Hi everybody. Andy here with etrailer. Let's take a real quick look at this RoadTech TPMS for your RVs and trailers. Now this system is going to help you keep an eye on your trailer's tires while you're driving by giving you real time pressure and temperature readings on your tires. So instead of discovering a problem after pulling over, you're gonna be able to see pressure drops or overheating tires as they happen. That's gonna give you the opportunity to address the issue before it leads to a flat tire, a blowout or another kind of roadside problem.

Now one nice advantage is the com compatibility that this has with both rubber and metal valve stems. So this is going to work with a wide variety of RVs, utility trailers, cargo trailers, and other towing setups, all without requiring special hardware. The monitoring range covers pressures from one all the way up to 218 PSI. So this is going to be suitable for everything from lighter duty trailers to heavy duty trailers that run higher tire pressures for added peace of mind. These tire sensors include anti-fat locking hardware that's going to help you keep them securely attached while you're traveling or parked.

So you're not gonna have to worry about somebody coming by and easily taking these off when you have them locked down with the included theft deterrent hardware. So this kit includes everything that you see here. You're going to get this 4.3 inch LCD touchscreen display. As you can see, I do have it powered on just so you can get an idea of how bright the screen is. And in my opinion, it's a pretty clear screen, especially considering my bright studio lights that I have turned on here.

This is gonna be a pretty simple operation as well. Pretty simple setup. And what I like about this is you are going to get this magnetic suction cup mount. I've got one some similar to this for my phone. I put the suction cup on my windshield, but you'll be able to put that on your windshield or your dashboard, but it is magnetic so it's gonna hold just like that and I think it's gonna hold pretty well.

As you can see, I'm giving a pretty good shake, so I do like that it's magnetic. It's gonna just go right on and stay on just like that. You're also gonna get this USBC charging cable, so you can plug one end here into the monitor and then the other end into a USB-A port to keep this charged up. As you can see, obviously this is running off of battery. Mine came with a full charge it looks like. So if you can't immediately plug this in, this is gonna be able to run off a charge for a while. You're gonna get this repeater as well to make sure that the signal is transmitting with full strength from the monitor back to the sensors. And speaking of sensors are gonna get the four cap sensors here and maintenance is going to be pretty straightforward if you need to replace the sensor batteries. The system's gonna remember the paired sensor setting, so you're not gonna have to go through the setup process again after a battery change. By the way, the battery lifespan road tech reports, it's gonna be about 12 to 18 months. Obviously, that's going to depend on how much you use these. And after your towing setup grows, you're gonna be able to, this system's gonna grow with it. You can get additional cap style tire sensors that are sold separately. They can be added to monitor more than four tires. Making this a good option for larger trailers or multiaxial applications on your screen. I'm including our part number for additional calf tire sensors. You get 'em in a set of two. So we do have the additional sensors available for you as well. Overall, this TPMS is designed to give you continuous tire monitoring. It's gonna help prevent tire related issues on the road and give you flexibility for a wide range of trailer and RV applications. It's gonna be really be a practical upgrade if you just wanna make sure that your tires are doing well as you're going down the road and help prevent any serious problems in the process. So again, these are going to be for the cap sensors, but we also have this system that comes with the flow through sensors, meaning those are gonna give you the ability to keep those sensors on while you're airing them up or letting air out, whatever the case may be. So if you would prefer the flow through tire sensors rather than just the cap sensors, I'm including our part number for that system there as well. You can take the part number, pop it in the search field of our website, that will take you to that system instead, and you can add that to your order instead. I think that's gonna wrap up our quick look today. Again, my name's Andy. Thank you for joining me.
