TireMinder

This TireMinder TPMS monitors the pressure and temperature level of the tires on your RV, motorhome, 5th wheel, motor coach, or trailer. The system utilizes sensors that attach to the valve stems of your tires. When a tire sensor detects an anomaly, it will wirelessly transmit an alert to the TireMinder digital monitor. Your monitor will emit an audible alert to notify you of an issue and will display details regarding the anomaly. A signal booster is included to provide a constant, strong transmission, and to eliminate electronic interference.



Initial Setup

The TireMinder TPMS is easy to set up and includes all mounting hardware and tools for installation. First, attach the TireMinder sensors to the valve stems of your vehicle's tires. Next, install the Rhino signal booster in a protected area near the midpoint of your full towing setup. Use the included holder to set up the LCD monitor on your windshield or dashboard so you can monitor your tires while you drive. Finally, assign the tire sensor positions through the monitor's Learning Mode. Once the tire sensors have been recognized by the monitor, you're ready to travel.


TireMinder Monitor

App Diagram

  1. Antenna (Raised) - The multidirectional antenna always needs to be extended when the TireMinder A1A is in use. When paired with the Rhino signal booster, the extended antenna helps eliminate electronic interference.
  2. Indicator Light - The light bar will shine red when the monitor is learning a sensor location and when the sensor is experiencing issues with a selected tire. The light will turn green when the monitor and sensors are paired and reporting no issues.
  3. Tire Information Reading - Readout of tire information refreshes every 6 seconds. Tire pressure information can be displayed as psi, kPa, and BAR. Tire temperature information can be displayed as either Fahrenheit or Celsius. The Auto-Search option allows the monitor to scroll between all of your sensors automatically and display the pressure of each in 6-second intervals.
  4. Current Tire Selection - The circles indicate the position of your tires. A dark circle means that the tire is currently selected for displaying information. A white circle means that the tire is paired and is transmitting information, but is not selected.
  5. Current Mode - Displays the current operating mode. If "M" is displayed, then Monitoring Mode is activated. This mode receives updates and alerts, and will be your primary screen after initial setup. If "L" is displayed, then Learning Mode is activated for use during tire sensor installation.
  6. Leaking Indicator - There are 2 indicator symbols that show up when the tire sensors detect a loss of pressure:
    Leaking Icons
    A. Rapid Air Loss (Blow Out) - This indicator displays when a tire loses 3 or more psi in 2 minutes or less. This generally occurs when the tire is severely punctured by a large, sharp object causing rapid air loss.
    B. Semi-Rapid Air Loss - This indicator displays when a tire loses 6 or more psi in 2 to 10 minutes. This generally occurs when a nail or other sharp object punctures your tire, causing semi-rapid air loss. This indicator may also be shown when there's a rapid drop in temperature causing a decrease in pressure.
  7. Down Button - Use to move across the screen to select the tire or option you want.
  8. Power Button - Press and release to turn on the receiver. If the monitor doesn't light up when this button is pressed and released, the monitor needs to be charged. To turn off, press and hold until the screen goes blank.
  9. Measuring Unit - Description of current measuring unit. Primarily displays the tire pressure in psi and temperature in Fahrenheit.
  10. Battery Life Indicator - Shows how much battery life is left in the monitor. Under normal use, the monitor will run for over 2 weeks before needing a recharge. If the last bar disappears, the unit will beep multiple times and the battery icon will flash with the word "Monitor" underneath it. If not plugged in, the monitor will shut down completely.
  11. Temperature Indicator
    Temperature Icon
    This indicator will flash when a tire's internal temperature exceeds 167 F (75 C). If the temperature exceeds 185 F (85 C), it will remain flashing and it will beep. Whenever you see this alert, pull off the road and find the cause of the alert. This alert is usually triggered by a stuck brake caliper or an overheated bearing.
  12. Pressure Indicator
    Pressure Icons
    A. Normal Pressure Loss - This indicator will flash when a tire's pressure has dropped 15 percent below its baseline pressure. If a tire drops 25-50 percent below its baseline pressure, the alert will look the same as above except it will be half full. If a tire drops below 50 percent, the icon will show empty. Whenever you see any of these alerts, stop at the next rest area and check the tire that is triggering the alert.
    B. High Pressure Alert - This indicator will flash when a tire's pressure rises 20 percent above its baseline pressure. The alert will repeat after one hour unless the condition is corrected. Whenever you see this alert, carefully bring your vehicle to a stop and check the tire that is triggering the alert. If the high pressure is within safe tire pressure limits, you may need to adjust your baseline pressure.
  13. Up Button - Use to move across the screen to select the tire or option you want.
  14. Select Button - Use to confirm option or select tire.

Multiple Wheel Layouts

Wheel Layouts


The TireMinder A1A TPMS is able to configure multiple wheel layouts and display them on the TireMinder monitor. The A1A can support a layout of up to 22 tires. Some examples of popular layouts are shown above.


Tire Sensors

Tire sensor Install Diagram

  1. Fasten the hex nut onto the valve stem by turning it clockwise. The nut must be positioned at least 1/4" from the top of the valve stem.
  2. Thread the sensor onto the valve stem and hand-tighten.
  3. Rotate the hex nut counter-clockwise towards the sensor. Use the included locking wrench to tighten the hex nut against the sensor.

Make sure your tires are inflated to the pressure level specified by the manufacturer prior to installing the sensors. These pressure levels will be used as the baseline to determine the high/low pressure warnings. It's best to install the sensors when your tires are cool.


You can also install flow-through adapters (sold separately) that let you air up your tires without removing the sensors. Simply screw the adapters onto your valve stems, and screw the sensors onto the adapters.


Brass vs Aluminum Tire Sensors

TireMinder sensors

Your vehicle's tires will have either rubber or metal valve stems. RVs, motorhomes, 5th wheels, and trailers will generally have rubber stems with brass valve cores or metal stems with steel, chrome, or nickel valve cores - all of which work with the TireMinder brass sensors. This TireMinder kit comes with 4 brass sensors. You will only need aluminum sensors (TM-2ALUM - sold separately) if you're towing a car or light truck with built-in TPMS and aluminum valve stems.


It's important to choose the correct TPMS sensor for your vehicle. Pairing the wrong metals together may lead to galvanic corrosion, which makes it impossible to remove the sensors from the valve stem. If this happens, you will need to replace the valve stem or, in some cases, the whole tire. Matching the sensors to the construction of your valve stems will ensure the sensors won't corrode.


Rhino Signal Booster

Signal Booster

The TireMinder Rhino signal booster improves the 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. This is crucial for operating the TPMS on large vehicles such as RVs, 5th wheels, or motorhomes. 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.


Signal Booster Install

Even though the booster is weatherproof, you'll want to install it in a protected area on the underside of your vehicle to prevent corrosion. The optimal mounting location for the booster is in the medial section of your vehicle. This allows the booster to communicate clearly with all of the tire sensors. Other possible mounting locations for the booster include your battery compartment, attached to your license plate light, or on the front of your car hauler.


Once you've mounted your booster in a good location, connect the red power wire and black ground wire to a 12-volt or 24-volt power supply line. The booster needs to be mounted securely to reduce vibration. Zip-ties are included to fasten the booster and wires to your vehicle or trailer.

Video Transcript for Review of TireMinder TPMS - RV,Trailer - TM-A1A-4

Today we're taking a look at the TireMinder RV tire pressure monitoring system. Now this system allows for constant monitoring of a vehicle or trailer's tire pressure and temperature. It can receive wireless information from up to 22 tires, zero to 232 psi. It comes with four transmitters, but you can always add more. It makes it great for multiple tire layouts such as a camper, a truck and camper, a truck and fifth-wheel, RV and towed vehicle, a truck and trailer, or a single coach.It comes with a hard-wired booster, and then on the monitor, we have the extendable antenna, so that's going to increase our wireless range. Right here on the booster, we have the built-in antennas.

It features the simple power and ground wires that have the alligator clips, so those can be connected to any power source that provides a constant 12 or 24-volt power feed. Now the booster not only provides greater signal distance, but it helps eliminate signal interference.This unit, again it comes with four transmitters and it comes with the necessary batteries, so if we open up the pouch here, I just have the batteries all tucked away. It comes with multiple batteries, all that you need for this kit. The transmitters simply screw onto the valve stems of each tire. Each transmitter features a weather-resistant design.

The monitor, which is right here, has a nice large display on it. It's rechargeable. It displays psi and temperature for each tire. It has a battery indicator that allows you to know when it needs to be recharged, and it comes with the power cable and it comes with your versatile charger so you have it so you can charge it from your vehicle, and then you also have it to where it can be charged using a wall outlet.The monitor also offers visual and audible high-low pressure alarms. You can customize the monitor to your needs so you can raise or lower the baseline pressure for each tire.

This allows you to teach the monitor what pressures you run in your set-up or in your rig. It notifies you of many different alerts, such as rapid air loss or blowout, semi-rapid air loss, normal pressure loss, high temperature warning, high pressure alert, and so on. It also features single action memory delete which allows you to delete information if and when needed. It features front and rear disconnect and reconnect modes, as well as an auto-search mode.Now, it comes with everything that you see here on the table, so you get four transmitters. You get your signal booster.

It comes with an adjustable magnetic mounting bracket so that way you can mount your monitor and you can pivot it to get the angle you need for your particular set-up. That way, you can always have a clear view of the screen and of the monitor. It comes with the components to get that installed and to attach the monitor to the bracket, and that is a pivot bracket, so again, you can adjust it as needed. It comes with your charger set-up. It comes with anti-theft locking nuts. It also comes with a locking wrench with a valve core tool. It comes with additional O-rings, which are for these right here.Now, to install the batteries, all you've got to do is remove the cap and then you can install the battery as needed. The O-ring is at the bottom of that threaded portion which creates a really nice tight seal. It keeps dirt and moisture away from the battery. Again, batteries are included, and it comes with a carryall pouch.That's going to do it for today's look at the TireMinder RV tire pressure monitoring system.

Consistently reads 5 PSI over actual PSI. Verified using calibrated pressure monitor. Occasionally (within 5-7 miles) gives false readings and alarm, 274 PSI. Settles down and provides consistent reading after about 10 miles of driving. Haven't verified the accuracy of temperature readings. No alerts when signal/heartbeat is lost. Good battery life. 593421


Comments

I called our contact at TireMinder and they suggest to make sure you are comparing the readings from the calibrated tire gauge and the TireMinder TPMS at the same time. To do this, turn on the TireMinder monitor, remove the transmitter from the valve stem, confirm the TireMinder is reading 0 at this point, use the tire gauge to record the current pressure of the tire, screw the transmitter back onto the valve stem and the monitor should display the current tire pressure. Compare the two readings. Since the tire pressure can change throughout the day this method will insure the two readings will be direct comparisons.

This is a great TPMS and an essential tool for my motorhome travels. We have a tow car and that has sensors on it too. Unfortunately for me, the only time I wasn't using it was when I had a problem. Luckily there was no damage and this highlighted to always be diligent when it comes to tires. 726319

We received the Tireminder package 2 days after ordering. Everything was included, and because we were planning to leave on a 4-day trip with our trailer, I immediately installed the unit. Everything went together with no problem. The biggest issue for me was where to mount the booster unit. Photo Booster-1 shows my solution, I mounted on the back of my tongue jack. My original plan was to put it in the compartment with my batteries and propane tanks, which is beneath the Diamond plate cover in the photo, but the instructions said do not put it behind a metal cover. I installed the tire sensors and programmed the monitor following the instructions in the manual, and everything clicked! Interestingly, when I went back into the house, to put the monitor on the charger, I found the monitor would easily detect the tire sensors, even while sitting at my kitchen counter, about 100 ft. away and through four walls and a garage door! Deliberately set the tire pressures low, and was very gratified to see that after sitting, and cooling over night, the monitor went to alert mode the following morning. I adjusted the tire pressures properly and the alert cleared, so we headed out. Having suffered blow-outs on trailers, and having to repair /replace not only the tire but trailer body parts as well, My wife and I both feel much more at ease with the TireMinder on our trailer tires. 707702

TPMS works perfect and fairly easy to set up - only odd thing is no mention in manual the display morphs into a layout that matches the tire layout once setup complete. It is automatic. I have bought many times from etrailer and always get excellent service! Decided to get the TPMS as shredded a tire and also had some minor damage to trailer. Decided TPMS cheaper than fixing trailer again. And maybe get off road before tire damaged beyond repair. 682571

Love the product, great piece of mind to monitor the tire pressures and temperatures in real time. Able to catch a problem before it becomes a "real" issue. Easy to install and use. The only negative is the wrench included in the kit. It is light and will bend if the locknuts on the transmitters are very tight. 681865

Ask the Experts about this TireMinder TPMS

Do you have a question about this TPMS?


  • What Causes Trailer Tire Blowouts
  • Every trailer tire has a load range rating specific to that particular tire. For example, we have the ST225/75-15 trailer tire in three load range ratings; Load Range C (2,150 lbs per tire), Load Range D (2,540 lbs per tire), and Load Range E (2,830 lbs per tire). If the gross trailer weight (GTW) exceeds the tires load range rating then the tires will be susceptible to blowouts. In addition to load range ratings, trailer tires also have a speed ratings specific to the tire. The speed...

  • Should Trailer Tires Run with 10 Less psi During the Summer
  • There are 2 common misconceptions about trailer tires that can definitely lead to blow outs. The first is to fill the tires to the psi listing on the trailer instead of on the sidewall of the tire, and the second is to reduce or increase the air pressure. Both of these are incorrect and can/will lead to tire failure. When filling up your trailer tires you want to make sure they are cold (after the trailer has been sitting overnight) and then fill them to the psi rating on the sidewall....

  • When to Replace Trailer Tires on a 5th Wheel Trailer
  • Trailer blowouts can be caused by several different things including heat, overloading, and road conditions. There is a difference between the amount of plies in a tire and its actual ply rating. Basically, due to advances in technology and materials a tire with 8 plies could have a 10 ply rating. To answer your first question going with a higher capacity or load range tire than what you have now would provide you with a stronger tire and higher ply rating. It will not increase the capacity...

  • Should Trailer Tires be Under Inflated when Traveling Through Desert Heat
  • It is actually unlikely that the air pressure in the tires will increase by 10 psi even in the West Texas heat. You might see an increase of about 5 psi maximum. You would still not want to under inflate the tires though because that could actually be worse than having a slightly higher air pressure. The rule of thumb on tire pressure change due to air temperature is 1 psi for every 10 degrees (Fahrenheit) in temperature change. In most parts of the United States the difference between...

The TireMinder RV Tire Pressure Monitoring System, part # TM-A1A-4, would be a great addition to your setup. This wireless monitor tracks the pressure on all your tires and displays them constantly. Keeping up with your tire pressure is one of the best ways to improve your...

  • Can Tires w/Different Pressures be Monitored at Same Time with Tire Pressure Monitoring System
  • That is not a problem. The Tire Pressure Monitoring System # TM-A1A-4 can be set up for different configurations: RV, RV with towed vehicle, truck, truck with 5th wheel, vehicle, or vehicle with trailer and will monitor the different tires with different pressures at the same time.

  • Fitment of Slide Out Stabilizers on a RV
  • Good news, I can help you understand why you would want these stabilizers for your RV. Stabilizers like the # UF19-960002, work to keep your slide out level, prevent sagging, and damage to your RV's extension tubes. They are designed to be used with your other stabilizers on your RV for an overall stabilization of the unit when parked. There shouldn't be any room for the stabilizer to have movement therefore no banging against parts if installed properly. If you are concerned about...

  • Tire Pressure Monitor System for Multiple Trailer
  • What you can do is order the TireMinder RV Tire Pressure Monitoring System # TM-A1A-4 for each of your tow vehicles. This comes with 4 sensors. To add additional sensors for the additional trailers we have the # TM-2ALUM for a quantity of 2 aluminum sensors or part # TM-2BRASS for an additional 2 brass sensors. These do not need to be paired to the monitor and will work out of the box. You need to pick the sensors based on the metal used on the trailer's current valve stems.

  • Can Tire Pressure Monitoring System be Used with Tire Pressure Monitoring on 2009 GMC Yukon
  • Tire Pressure Monitoring System # TM-A1A-4 can only read its own transmitters and won't be able to utilize the system on your 2009 GMC Yukon. But if you want to monitor the tire pressure in the Yukon, like when flat towing it behind an RV for example, then this system will work. I have included a link to a video review of this system for you.

  • Recommended Tires And Tire Preasure Monitoring System For RV
  • I recommend the Taskmaster Provider ST215/75R14 Radial Trailer Tire - Load Range D # TTWTRTM2157514D which is the highest rating we carry in that size. It is one step down from the 10 ply rating, with a rating of 8 ply. It has a capacity rating of 2,200 lbs at 65 psi. It has automotive-grade tread with increased siping, so it really is a superior product. This tire has a max speed of 81 mph (speed rating M). We also have the TireMinder RV Tire Pressure Monitoring System - Signal...

  • RV RIMs and stem size
  • The valve stem size on a wheel is dictated by the size of the wheel. In order to find a valve stem that is .453" you would likely have to go all the way down to a wheel that has a 14" diameter (15" wheels also sometimes come with this size valve stem). Unfortunately because of the size of your 5th wheel, this really isn't feasible. I did some research on the TPMS that comes with the new Chevy Duramax trucks and it appears that they are VIN specific, but you may want to check with your...

  • Will Hopkins Tire Pressure Monitor System Interfere w/2013 Toyota Tundra Factory Monitoring System
  • I spoke with my contact over at TireMinder about the tire pressure monitoring system # TM-A1A-4. He stated that it should not interfere and that they have not had problems come up with the 2013 Toyota Tundra. I have included a link to a video review of the system for you.

  • Will the Tire Minder TM-A1A-4 Replace the Factory TPMS on a 2014 Ram 1500
  • Since you already have the built in TPMS system on your 2014 Ram 1500, it would probably be a bit of an overkill to add a TPMS system like the # TM-A1A-4 to the truck unless there was some sort of malfunction you were experiencing. With that being said, these are going to be perfect for your tandem axle trailer. These sensors mount directly onto the valve stem of your trailer tires and the LCD monitor will provide you with updates every 4 minutes on the tire pressure. This is powered by...

  • What Causes Tire Blow Outs On a New Pop-Up Trailer
  • There are a number of reasons as to why a tire can blow but the most relevant to a new trailer would be the amount of psi in each tire. The psi in each tire will need to be set to the max psi listed on the sidewall of the tire while cold, not any less or any more no matter how much weight you have on the trailer. Once you have done this then you will need to be sure you have not overloaded the trailer. It might also be worthwhile to check the date code on the tries but this won't be as...

  • Replacement Tire Sensors for TireMinder TM66 System
  • Yes. You will be able to use these Brass Tire Sensors for TireMinder # TM-2BRASS with your TM66. From what I was able to find out, the TM66 system is the same system as the Tire Minder TPMS for RVs # TM-A1A-4 and # TM-A1A-6 ; the only difference is that the A1A systems came with a larger LCD screen. The TM-2BRASS will work with all brass and steel valve stems. If you have aluminum valve stems you can use part # TM-2ALUM as a replacement.
