While on the road, it is very important to regularly maintain your tires and make sure they're inflated correctly. If your tires are underinflated or overinflated, they'll develop irregular tread wear and become prone to overheating and blowing out. The TireMinder i10 TPMS helps protect your investment and keep your family safe by monitoring your tires and alerting you of any signs of danger before disaster strikes.

4 Waterproof Sensors

TireMinder i10 TPMS Waterproof Sensors

This TPMS includes 4 sensors that let you individually monitor each tire on your application for changes in pressure and temperature. These brass sensors are able to work on rubber, steel, chrome, or nickel valve stems. Every 6 seconds, they will check the pressure and temperature again. These durable sensors are waterproof, which means that they can be used on boat trailers and other marine applications.

Simple Setup with Color LCD Monitor

The color LCD monitor will provide you with visual and audible cues to warn you of dangerous changes in tire pressure and temperature, as well as alert you of changes with the monitor battery, sensor battery, and sensor signal. Before you begin setup, make sure the monitor has been charged and the repeater and sensor batteries have been installed.

TireMinder i10 TPMS Waterproof Sensors

Select your RV or trailer configuration or the locations of the tires you want to monitor. Then select one tire location, install a sensor on the corresponding tire on your RV or trailer, and the current PSI will automatically appear on the screen. With the purchase of additional sensors (sold separately), you can monitor up to 20 tires, which is perfect for a fleet. This system can display up to 10 tires at a time, alternating between the tires of the "front" or drivable application and the tires of the "rear" or towable application. Sensors can be added, moved, deleted, or replaced at any point, even after initial installation.

You can set the tire pressure in psi, Bar, and KPa. If you choose psi, you can set the tire pressure anywhere from 0 psi to 199 psi. As for the temperature, you're able to switch between degrees F and degrees C, and the system will alert you if the temperature exceeds 167 degrees F. With the app, you are also able to disconnect and reconnect to different vehicles, RVs, or trailers. This is useful for those who switch between different applications, such as a Class A motorhome who sometimes tows a car. It also can store pressure and temperature information for up to 4 vehicles, or 40 tires.

RHINO Repeater Boosts Signal

TireMinder TPMS RHINO Repeater

This repeater helps improve signal strength and range of the sensors. It has dual Hi-Db antennas that let the booster cut through signal interference coming from wireless electronic devices used in surrounding automobiles. It also ensures that the link from the sensors to the monitor is strong and continuous. The unit has a green light on the front panel to indicate it has power and a blue light that blinks when it transmits a signal.

Easy Installation

TireMinder i10 TPMS Installation

This TPMS system includes 8 batteries, 4 locking nuts, 4 O-rings, zip ties, and a wrench. Once the batteries have been inserted and covers have been re-installed, remove the cap of your valve stems, thread the locking nuts onto the valve stems, and install the sensors. Lastly, secure the locknuts against the sensors with the wrench.

The weatherproof and dustproof Bluetooth repeater can be installed anywhere on the exterior of your RV or trailer between the rear axle and king pin. The optimal mounting location for a towable camper is toward the front whereas the optimal mounting location for a drivable RV is toward the rear. it is not recommended to install the repeater inside your vehicle, as you might experience signal blockage. Use either the adhesive (included) or hardware (not included) to attach the repeater and wire it to a power supply line. In order to reduce vibration, make sure it's securely mounted. Then connect the black wire to ground, and the red wire to power. Zip-ties are included to fasten the booster and wires to your RV or trailer.

Haven't installed and used yet but my previous tireminder was excellent, just didn't monitor higher pressure of new tt. Service from etrailer was superb as usual. They always have products in stock and deliver promptly.


Purchased this for our trailer a few months ago and am very happy with it. It took just a little bit to program each wheel but wasn't too much trouble. The screen is easy to see and is not overly large. Now I have peace of mind when towing our camper. I like it so much I bought one for my son as a Christmas gift. Great product at a good price.


Great product at a great price along with eTrailer’s great service… winning combination!!!

Absolutely flawless… no problems whatsoever.. we did a 4000 mile 13 state out west trip in the spring and had no issues at all!!
Donny W - 09/30/2022


I bought the TireMinder kit last summer (2021) right after a trip where my 24' Wildwood trailer had a blowout. I didn't even know the tire was flat until I pulled into the RV park and noticed it was completely shredded - not sure how long it had been like that. By some miracle neither the trailer nor the wheel were damaged. The TireMinder was easy to install and works great, giving me peace of mind that next time I will have some advance warning when something starts to go wrong with one of my tires. I installed a simple connector in the power line for the booster so that I can easily disconnect it when the trailer is parked, without removing the battery cover. The display unit works for 7 or 8 hours before needing to be recharged, which works great for me since I don't want to drive for that long in a day anyway. Highly recommend!


This produce works well. I can tell when my tire pressure is low and which tire needs my attention.

We brought this item to monitor the tire pressure on our 5th wheel camper. The products still works great after a year using it.
Ken - 10/11/2022


Best peace of mind I could have purchased. Easy install. Programming is easy when you follow the instructions to a tee...especially the part about reading the book first. :) Wish this technology would have been available years ago...

Still think its an awesome safety and peace of mind product. Keeping trailer tires properly inflated is the secret to successfully keeping them in one piece.
Loren - 10/08/2022


I did a lot of research on this system, the product arrived as described. The instructions were pretty easy to follow but had to go back and make some changes on the set up. Other than that insulation was straightforward. Installed the amplifier in the desired position as instructed. Going to go out on June 18 to test out.
I have used the trailer for several of my cougar fifth wheel purchases and I have to say that their customer service is outstanding! And will continue to use them on all future purchases.


I am an RV Tech. As such I realize the value of having things such as the TireMinder to monitor and protect the important systems on my trailer. I initially thought I could get by by just checking my tires every so often. But then I realized that "every so often" would not protect me from a fast leak in a tire or a rapid temperature spike. So, to reduce the chance of something that is likely to occur sooner or later, I got a TPMS.

I got the i10 model because it has very good online user reviews. I got it to use on my camper in a couple months when I start RVing.

My initial impression is that the i10 components are well made, user friendly and have the functionality I desire. Once I get the TPMS installed and make a trip I will be able to provide a follow-on review.

I used the i10 for several months. It is a good system for monitoring tire pressure and temperature ... but I had some issues: 1 The monitor backlight got progressively dim. I contacted Tire Minder and they quickly sent a replacement. Havent used it yet. 2 Although noted in the user manual, it could take a minute or two for the system to start reading the temps and pressures. Not a big deal ... but does delay driving sometimes. 3 Occassionally the readingbon a tire or two would freeze or stop. I dont use the included range extender, so it could be signal interference. Only a nuisance to me because 95 of the time all is good. At the moment I would say the i10 is a good product. Until the original monitor went bad I was happy with it. But my final opinion will have to wait and see how the new monitor works.
Dave H - 01/31/2022


I've been ordering from etrailer for a couple years now and have always been very satisfied with their products and great service. I highly recommend them for all of your needs.


Seems to be of good quality
Going through
the installation instructions now
Would you send me a receipt via email so I can attach to warranty card
Thanks in advance


The sending units are a pain to get organized and installed properly with the cute little locking wrench and it’s more difficult to change vehicles. The booster is another cumbersome detail the designers should have omitted. Seems like you have to hold your mouth correctly to get four of the sensors to work all the time.


Purchased this to try to avoid blowouts on our RV trailer. Installing the booster was a cinch. I did have an issue with one of the sensors, after swapping tire positions and checking the battery it turned out one sensor was defective.

I called the folks at TireMinder and they sent out a new sensor, extra batteries and a return label for the defective one. New sensor installed without issue.

All 4 sensors read within 1psi of my tire gauge and tire pressure readings were instant and constant. Initial trip with the system was a 9.5 hour drive and still had 1 bar left for battery power on the monitor. Forgot to turn the monitor off and still had 1 bar the following morning. Recharged monitor for return trip. Travel time home was 9 hours still had 1 bar remaining again.

Would highly recommend TireMinder to keep an eye on pressures and to try to avoid blowouts.


What can I say? It has already saved my bacon on our first long trip using it. Driving across rural Oklahoma, I saw that one of my 5th wheel RV tires was a bit low, so we checked a few gas stations (3AM) but none of them had working air compressor. Given that it was just a bit low, we continued on, thinking to air it up at the next town along our route. Fifteen minutes later, and alarm went off on our TPMS, and I could readily see that the tired next to it went immediately from 80PSI to 40PSI. Although I could not sense any change in the handling of my RV from the cab of my truck. I was able to slow down, find a safe place to replace the bad tire and evade a catastrophic situation had I not installed this TPMS. IT WORKS! ... and I would not go out on the road without it. Definitely worth the investment.


Essential to our travels. The tire minder has given us huge peace of mind. The alarm went off, for the first time, traveling through a Wyoming rain storm this past summer. We pulled over and investigated and were unable to make a determination of what might have happened. We returned to the vehicle. The situation had stabilized and we continued on our way, confidently. Since the weather has cooled off (in California) the alarm has notified us twice recently of low tire pressure that corrected itself as the tires warmed going down the road. I recently aired up all 4 tires based on the numbers on the tire minder. We have had zero problems with the sensors on the valve stems. It’s easy enough to either charge or plug in the screen inside the truck. We have no issues reading the screen or operating the monitor. We wouldn’t hit the road without the tire minder. Highly recommend.


The sensors on the tip of the valve stems stop working intermitantly,
dash panel shows very low air pressure, check with air gauge and tire pressure is correct. Reinstall sender and it works ok for a few times then another one or two send low air pressure signal. A bit annoying.


The package arrived in good condition. The installation took around 45 minutes to complete. That included reading the book, charging the unit, and adding air to the tires. The instructions are well written and are complete.


etrailer has to be one of the BEST companies to deal with!


I am very pleased with the system as a matter of fact it saved us a blow out on the very first trip using it


works as advertised.
only possible negative
is the length of time it takes to come up with pressures after being shut down for awhile.
Seems to be accurate. reads within one PSI of my digital pressure gauge.


instructions were very good, product is what I expected.

Im very happy with my tire minder...the peace of mind is extremely welcome.

Worked as advertised


All parts come loose in a generic box.

I will have our Customer Service team reach out to you.
-- Etrailer Expert Jenny N - 04/13/2022


Lets you know if there is a tire proble m.


Low level air leaks from the caps resulted in loss of tire pressure during storage and while driving.


Seems like a good item. They shipped USPS - which took 9 days from their warehouse to KY.

  • How to Protect Your RV From Tire Blow Outs
    The best way to protect your RV from a tire blow out is to inspect and take care of your tires and keep them properly inflated.

Tires typically blow out from excessive heat from underinflation, overinflation, overloading, surpassing the speed rating, flat spots/sidewall rubbing, and bent spindles.
