TPMS…How did we live without it?????
The TPMS is great. Shipping was quick. A friend who already has a TPMS assisted in setting it up. This TPMS is actually meant for a tractor trailer but we were able to set it up for the motor home with 6 tires, car dolly with 2 wheels, and the toad with 2 wheels. In just 2 trips it has already saved a rim on the car dolly by telling us about a flat as soon as we started on the trip due to side wall break and just before the 2nd trip, let us know that we had a low tire. I love this thing.
On hot Florida days we can monitor the temperature of the tires as well as the pressure. With a little research I was able to find that 20% for the high pressure alarm setting and 10% for the low pressure setting is working for us. It is easy to adjust your settings when required. I also like that this monitor has an alarm as well as a red flashing light when there is a problem. We set the high temperature at 150 F. We have seen two fifth wheels on the highway on our last trip with tire blow outs that blew out the side of the trailer. With the TPMS that situation could be avoided. 👍😊Shared by Mar

This little purchase gave me SO much peace of mind on our recent family trip with our new travel trailer. A tire blowout on a travel trailer can destroy the trailer and cause a terrible accident, so I was scared out of my mind about that happening to my family. Our trailer dealer said that we have to keep a close eye on our trailer tires and recommended a TPMS. I got on Amazon and found this – a little skeptical at first because it was solar and I wasn’t sure if the distance from the unit to my trailer tires would work, but it works like charm.
Just to be sure, we checked the tire pressure with a gauge after every few fillups and the tire gauge read almost exactly what the TPMS display said, within 1 PSI give or take. This is the one product I recommend to other people on the RV forums. By the way, there’s NO getting these off without the little tool it comes with, so don’t lose that!Shared by Gina CC

I am VERY happy with this product!! It performs AS ADVERTISED!! One of the transmitters was faulty. I decided to buy the SIX sensor model for just THAT reason. I only need four for my coach, but I got six…..so I would HAVE extras. I am a realistic person. Electronics as complex as those manufactured in this current world do not always WORK!! Plan for it, EXPECT it, and STOP whining when it happens!! I am 67, I am MORE amazed that ANY of this stuff works AT ALL, let alone there is a glitch every once in a while!! Over half of the negatives complained about how hard it was to program. GET OVER IT!! There is a protocol you NEED to follow to get correct readings from EACH tire!! SLOW DOWN, READ INSTRUCTIONS, FOLLOW INSTRUCTIONS. Easy peasy, lemon squeezy!! They are hard to get on? Yup, that is so they are HARD to lose!! I expected I might lose one, another reason I bought SIX!! Think about it? That little sensor is flying around the circumference of that tire at 65 miles an hour!! I am an engineer. There is a mass, centrifugal force, and moment formula. Would you like me to calculate the forces at work? You want it to come off easy? It will, at the WRONG moment!! Then you will whine about that also. The resulting comfort and sense of security these little guys provide are WELL worth the journey!!Shared by Ro$$

When digital TPM systems first came out 6 or 8 years ago I purchsed what was pretty much available at the time and was so displeased with the reliablity and service I recieved fro the supplier I was very skepticle that a good system could be found. While on the road this year I found via a fellow RVer using this particluar system and we discussed at length all aspects of the TST system.
I purchased the mod# TM-507G flow thru system for use on our Airstream 30ft Classic. The features that make this so great is that they work as discribed. Every five seconds it continually monitors and displays psi and tire temp. on a rotating basis of each tire. The folks from TST are fantastic. They are courtious, professional and very knowable about their product. The one item you will want to have is a digital tire gauge to use when making sure your initial tire pressure is correct because old style gauges won’t give be close enough.Shared by JO

To put B-Qtech TPMS to use, it’s essential that you set up the sensors first, which should only take a few minutes. Once you have replaced a sensor due to damage, you must reset the sensor setting before resuming operation.
I was apprehensive about the low price and how it would work, there are many more systems out there that cost hundreds more. It only took one time to know how well it does work! It saved my camper and my family! On our way to the campground, and going nearly 70mph, the device gave an audible and visual warning that one of the camper tires had lost all of the air. I pulled over, and sure enough, the tire was flat and starting to shred, a complete failure. Without the monitor, I wouldn’t have known the tire went out and it could have shredded into the other tire behind it. I don’t really want to know what would have happened if we kept going without a warning.
This little system, though cheap, worked perfectly on its maiden trip. I’ve already recommended it to family members who also pull a camper.Shared by Amazon Customer

What is An RV Tire Pressure Monitoring System?
What it does?
The tire pressure monitoring system for RVs works by using its sensor system in monitoring the air pressure of tires. A basic one sends an alert to the driver in case the tire’s air pressure goes down to a specific level.
Some of these systems come built-in with features, like temperature monitoring, fast leakage alerts, and low and high-pressure alerts. You can also find certain models of this system that let you incorporate additional sensors.
A tire pressure monitoring system for RVs also alerts drivers on various scenarios that might lead to tire blowouts. These scenarios include hot tires triggered by overloading or component failures, like bearings or brakes, slow leaks coming from a puncture, and fast leaks coming from tread separation, sidewall failure, and puncture.
How it works?
For the system to work, it makes use of sensors that transmit data or info to at least one module inside your vehicle. For instance, if your tires get over or underinflated, the system will work by activating a warning light on the dashboard. In general, a steady light indicates that you need to check the tire pressure.
In case the light is flashing then it should be the tire pressure monitoring system that you have to check. One more thing that you have to be aware of regarding this system is that its modules are programmed based on a range of tolerable or acceptable circumstances.
If you own the direct TPMS, then what is allowed should be around 28 to 35 lbs. psi (per square inch) of air inside the tire. All car models from the year 2008 and newer already come with TPMS.
Such a system is already equipped with sensors that are mounted on each tire as a means of measuring pressure continuously and alerting drivers in case they detect under-inflation. Once the tire is inflated and reaches the appropriate pressure, you can expect the light to go off.
Why we need an RV TPMS
A TPMS alerts the driver when a tire falls below 25% of the acceptable pressure level. These systems will even pick up problems before the tire’s sidewall starts to fold over or rub together, which is the first visual sign.
This will save you from these life-threatening situations caused by flat tires, underinflation, overinflation and blowouts.
If you continue to run your vehicle on these troubled tires, the situation only gets worse, for instance, it is more likely that the remaining air will escape from your tire.
Save Repair and Maintenance Costs
TPMS will ensure you know when there’s a problem before tire failure can cause damage to other components such as the axle or wheel, thus saving you time and money on maintenance.
Better Fuel Economy
Every 10 percent of tire underinflation reduces your fuel usage by one percent. Thus if you are intimidated by the cost of a TPMS, think about the saving on fuel bills in the long term.
Extends Tire Life
An underinflated tire will be in contact with the road more, thus more wear and tear. In addition, underinflation tends to be the main reason tires end up failing. Underinflation can cause a variety of potential problems: sidewall breakdowns, heat buildup, tire disintegration, and ply separation.
These issues are all monitored by RV tire pressure monitoring systems and thus will extend your tire’s lifespan.
Underinflated tires will slow down your vehicle, causing your engine to work extra hard and produce more emissions. Simply ensuring that your tires are properly inflated before hitting the road is not only safe for you, but also the environment.
Types of RV Tire Pressure Monitoring System: Direct vs Indirect
There are two types of TPMSs: indirect and direct. Of course, each has its own pros and cons, and you must understand how they work to determine which one is a wiser investment, depending on your wallet and driving needs.
A direct TPMS would be ideal if you prioritize top notch performance and of course, have the money to pay for it. These devices are incredibly beneficial as they let you adjust pressure, send alerts right away, and track tire temperature. The only downside is their more expensive price tag, which however, is reasonable considering the benefits that you get.
If you would like a cheaper option, then consider an indirect TPMS, which are still useful in their own way. But their readings aren’t as accurate, they don’t use physical air sensors, and don’t track tire temperature.
These kinds of TPMSs work by using sensors inside your tires that’ll keep track of the pressure levels. As a result, a direct TPMS doesn’t only monitor your wheel’s revolution data, but it can also provide readings of things like tire temperature.
The system will transmit this data into a control module where it’ll be evaluated and determined whether there’s an issue. If there’s an inflation issue, the information will be sent to your vehicle’s dashboard, and the warning light will light.
It is worth highlighting that a direct TPMS sends the data through wireless means, allowing for quick and effective data transmission, and that all the sensors come with a specific serial number.
These specific serial numbers allow the TPMS to separate its readings from other systems on the vehicles around you. It also will separate the readings from each tire to ensure you know exactly where a problem lies, if any.
Another cool feature of direct TPMS is these systems aren’t susceptible to inaccurate readings due to issues such as tire rotations or replacements. In fact, resynchronizing the system after rotating or replacing tires is a straightforward process. What’s more, you can even use a direct TPMS on your spare tire.
Another plus is these direct systems’ sensors use long-lasting batteries, so you can expect them to work for about a decade or longer.
One downside is they can be prone to damages during demounting or mounting. However, overall, a direct TPMS is accurate and effectively ensures your tires are in tip top shape for safe operations.
An indirect TPMS works based on an entirely different mechanism. These devices don’t use pressure sensors inside each tire but instead evaluate tire rotational speeds and other signals to estimate their air pressure. Therefore, you cannot expect indirect TPMS to provide accurate readings like direct systems.
These systems will rely on your tire’s speed sensors, which are utilized by the anti-lock braking system, to evaluate your tire’s rotation speed. This data will be sent to the computer, which will use this data to determine whether there’s an issue with the level of inflation and light up the warning indicator when there’s a problem.
In comparison, indirect TPMS requires a lot less maintenance and enables easier installation than a direct TPMS.
Regarding downsides, in addition to the overall lower accuracy, these systems are even less reliable when you have unevenly worn tires. An indirect TPMS also needs to be reset after you inflate or rotate each tire.
Given this information, it’s quite apparent the indirect TPMS is less advanced and hence much cheaper. However, these devices could be a more cost-effective option for your budget and needs.
How to Choose the Right RV Tire Pressure Monitoring System
All in all, different RVers have different opinions about the best RV tire pressure monitoring system but to get your money’s worth, it’s necessary to assess certain qualities.
The purpose of virtually every RV tire pressure monitoring system is to notify people of the pressure of their tires. Any worthwhile TPMS will come with a display that’s readable and provides accurate data. In other words, the icons should be easily visible and understandable.
Additionally, in case of emergency, the display needs to have a red light that would alert you about current situations. It’s also nice to have a display that features adjustable brightness for night driving.
RVs go everywhere. Recreational vehicles tend to be exposed to a wide range of environments in the outdoors so it’s essential to use stuff that holds together. The same rule applies to RV tire pressure monitoring system: look around for models that remain operational in extreme conditions like excessive heat, high humidity. Find out how the product will react to being submerged underwater or being soaked under the sun for too long. Research on what materials they’re made of.
If you’re lucky, someone somewhere already bought and experienced that TPMS and you can just base on their experience to decide whether your choice is good or not.
For most of the time, it’s widely advised that RVers look for models that they could install by themselves. After all, you have enough troubles to face as an RVer and you don’t want to struggle around an overly complex RV TPMS system. You might even end up wasting your money if you damaged or destroyed it.
If you’re not a crafty person and you’re not into DIYs you might need to pay a little more attention to how these kits are assembled and installed. It won’t be easy, but it shouldn’t be hard enough that you’ll need a technician just to get it working on your car.
Read product descriptions and review carefully. The TPMS kit should come at least already assembled and ready to be plugged to your car. You shouldn’t have to put it together yourself. Gravitate towards products that don’t have a complicated installation process.
Most tire pressure monitoring systems run on batteries so the battery will greatly affect your overall experience with your TPMS. Check if your system’s batteries are durable. Make sure they can keep up with different weather and temperature changes. Always consider the battery’s lifespan. You don’t want to lose power in the middle of the road.
Considering the characteristics of RV travels nowadays, it’s of utmost importance that the battery of your RV tire pressure monitoring system is heat-resistant. That should allow the battery to keep the system operational even if subjected to extensive heat for quite some time.
You might also want to look for a system with rechargeable batteries. These batteries are incredibly convenient for RVs to use as they don’t need replacing. As a result, you won’t have to spend extra money on new batteries.Some TPMS also offers solar-powered charging. It’ll cost you a little bit more, but it’ll be worth it in the long run.
How To Install an RV Tire Pressure Monitoring System
1. Setting System Alarm Parameters
Refer to the diagram on the last page of this manual where you wrote the sensor number for each tire.
- Next to each axle write down what your tire pressure is by axle and calculate what your alarm setting will be.
- High Pressure setting will be (20% above axle tire pressure).
- Low Pressure setting will be (10% below axle tire pressure).
- Front Axle Tire Pressure is: 100 psi
- High Pressure Alarm Setting will be: 120 psi (100 psi x 1.20 (or 20%) = 120
- Low Pressure Alarm Setting will be: 90 psi (100 psi x .9 (or 90%) = 90
These are industry standards for the initial set-up, some adjustment may be needed after your first trip. Every brand of tire operates differently, when some brands reach operating temperature the psi will increase 5 psi, other brands may increase 20 – 22 psi. During your first trip you will see if you need to increase your High Pressure Alarm setting. For the temperature it is recommended leaving it at the factory default of 158 degree F.
Choosing A Pressure Unit of Measure:
Press the SET button and hold it approximately 3 seconds until you hear the beep. You will first see PSI or BAR (for metric) in the first window. Use the + or – key to scroll between the two. When the one you want to use appears in the screen press and release the SET button. (Pressing and releasing the SET button in this mode is like saying yes to what the screen is showing you)
Choosing a Temperature Unit of Measure:
It will automatically move to the next window which will show you F (Fahrenheit) or C (Celsius) for the degree setting in the second window. Use the + or – key to scroll between the two. When the one you want to use appears on the screen press the SET button and release.
Setting High Pressure Alarm Parameter – Front Axle:
Now the front axle should be flashing with the words High Pressure on the bottom of the screen. Press the + or – keys to make the pressure scroll up and down. Once you reach the High Pressure setting you desire press the SET button and release.
Setting Low Pressure Alarm Parameter – Front Axle:
Now your front axle should be flashing with the Low Pressure showing on the bottom of the screen. Press the + or – keys to make the pressure scroll up and down. Once you reach the Low Pressure setting you desire press the SET button and release.
Do the same for the 2nd and 3rd axle.
Setting High Temperature Parameter – All Axles:
Last, will be the Temperature setting, we recommend leaving it at the default setting of 158 degrees. Press the + or – keys to make the temperature scroll up and down.
At this time if you had any axles that would not allow you to program a low 102 psi scroll back to them by pressing and releasing the SET button until you are back to the axle you need to adjust. Now the system will allow you to adjust it below 102 psi, adjust it to the desired psi and repeat for any other axles that may need to be adjusted. To save the data; press the SET button and hold it for approximately 6 seconds until you hear the beep. The screen should look like your rig is configured.
2. Programming Sensors to the Monitor
- Using the switch on the left side center of the monitor, push it up to turn the monitor on.
- Wait for the screen to warm up, your monitor may or may not show tires configured on the screen. If tires are showing the first time you turn your monitor on these would be from factory testing and are not your sensors. Note: If you would like to delete these use the +/- key to scroll to the tire showing on the screen, you will see a six digit code press and hold the SET button until you see this code change to FFF FFF. You have deleted the old code from the tire position. You do not need to do this, when you program your sensor to the tire it will delete the previous code and update the system with your new sensor code.
- Press and hold the CODE button on the lower right side down for 3 seconds until you hear the beep. At this time you will see all 22 tires on the monitor screen and the right front tire should be flashing. (Note: If a sensor is coded twice into the same position on the monitor, the previous setting will be deleted automatically. Once you start the programming or set-up functions if you do not perform a task in approx. 40 seconds it will time out and go back to the operating mode. If this happens you will have to restart the process with STEP 3.)
- Following your diagram, hold the monitor approximately 1-6 inches from the sensor as you screw the sensor onto the tire valve stem. You will see the FFF FFF automatically change to the code as the air pressure activates the sensor. If the code does not change within 16 seconds, back the sensor of the valve stem and reattempt. * I set the monitor on top of the tire or on the rim when I am screwing the sensor on the valve stem.
- Use the + or – keys to scroll to the tire you want to set up. The tire which you are programming the sensor to the monitor for should be flashing. * Ensure the tire you want to program is flashing on the screen prior to screwing the next sensor on the tire. Note: a. If you get an error message “Id LF” (for Low Frequency) and the “Id Err” (for Error). Move the monitor closer to the sensor and repeat.
- Once all the tires (sensors) are programmed press the CODE button and hold for approx. 6 seconds, until you hear a long beep. Your monitor screen should now look like your rig configuration.
- Release the CODE button, now your sensors are programmed. (Note: if you see a sensor has dropped off after you have programmed them, don’t panic. Merely repeat the steps starting at STEP 3 to reprogram the missing sensor(s).
3. Monitor Installation
Your system comes with three mounting options: a plastic tower with suction cup mount for window or dash, low profile mount for dash, low profile triangle mount for dash. Some people prefer to use Velcro or the small bean bags used for cellphones on their dash.
- Install the monitor on the dashboard using the low profile mount or mount it onto the windscreen or left side window using the suction cup provided ensuring you do not obstruct the driver’s vision of the road.
- Plug the power adapter into the cigarette lighter or auxiliary power outlet and connect the power cable to the monitor. It is recommended using a “keyed” power source when hard wiring.
4. Sensor Installation
- Remove the tire valve cap and mount the corresponding sensor on the valve using the wrench provided.
- The sensor is designed to be difficult to remove without using the wrench provided.
- Simply screw the wrench clockwise.
- If you trouble getting the wrench into the location you can unscrew the two halves of the Anti- Theft housing , keep the bottom part of the housing in place on the sensor and screw the sensor onto the valve stem by hand. Once the sensor is in place, pull the lower part of the housing up and screw the top half of the Anti-Theft housing onto it. The Anti-Theft housing will now spin when turned on the sensor. The reverse can be done to remove if necessary.
- If you do not need the Anti-Theft function, you may remove the Anti-Theft cover by simply unscrewing the two halves. Mount the inner sensor on the valve directly. If you do not use the Anti-Theft housing it is recommended to put a small bead of silicone around the seam where the sensor unscrews to replace the battery. This will give extra protection against moisture entering the battery housing in inclement weather.
How To Reset My Tire Pressure Monitoring System?
Things get more complicated if your system’s an indirect system. These sensors will require being reset using a scanning tool or magnet that you bought yourself or by a dealer.
Some of these systems will also have a reset button, which is located inside your glove box. This button will have to be pressed for three seconds with your vehicle’s ignition on.
Locate the battery and disconnect the negative cable using a wrench. With the battery unplugged, start your vehicle and press the horn for a few seconds in order to drain the remaining power in the battery.
After that, you can reconnect the negative battery cable. The sensors should be reset and the warning light should be off.
This process will vary depending on your vehicle, but directions should be found in the TPMS chart within your manual. If it’s not there, you can also check online on the manufacturer’s website.
If you’re getting new tires and the valve stems are also the tire pressure sensors, you should also change the valve stems.
Note that not all RVs have the TPMS reset button in the same place, so check your owner’s manual to find its location. Once you know where it is, put the key in the ignition and turn on the car.
Don’t start the ignition. With the key turned to the “on” position, press and hold the TPMS reset button. After a few seconds, the warning light should blink. Release the button and start the vehicle. Let it run for a few minutes to give the onboard computer enough time to recalibrate the sensors.
If it does not work, try The Magnet Method
- Have the key on, but the engine off and press both the unlock and lock buttons on your key fob.
- Once you hear the first chirp, use a magnet and place it over every valve stem in the following order: left front, right front, right rear, and left rear. Continue until the horn chirps for each valve stem.
- From there, it’s a simple matter of verifying the pressure readings located on your dashboard.
FAQs About RV Tire Pressure Monitoring Systems
1. Is there any brand of TPMS I should know of?
2. Do I have to install a range extender for TPMS?
3. Could I reuse old sensors?
4. How many sensors for TPMS do I need to use?
5. Is it possible to replace the battery of the sensors?
The batteries inside TPMS are lithium-ion batteries, which can last anywhere from five to 10 years. Of course, this range can vary depending on different factors, but five to 10 years is the general guideline with these batteries.
In most cases, the older TPMS sensors will have a lifespan closer to the five-year mark rather than ten years. It’s also essential we mention that these sensors only broadcast a signal when the vehicle’s moving as a way to save the battery.
It also helps that the signal occurs at irregular intervals, which is another way to save battery life.
6. How to disable the TPMS?
To get at the TPMS/HomeLink connector, just remove the dome light and you can see the wires going into it. Remove the connector, use a pick or other fine tipped tool and depress the top of pin 2 so it will slide out. Push the pin back into the connector in the 6th position and reinstall the connector. Reinstall the dome light and you are finished.
