Review of the TireMinder TPMS for RVs and Trailers

Hey everybody, today we're going to be going over and showing you how to install the TireMinder A1AS TPMS system for RVs and trailers. So the A1AS is a pretty advanced system. We're going to have tons of different alerts. They're going to notify us while we're driving of any potential issues or any issues happening as we speak. Now just some of these alerts here, we're going to have an alert for a rapid leak which is going to be a loss of pressure of three PSI or more and less than two minutes. So that's going to display a rapid leak alert.

The other alert we have is going to be a slow leak which is a pressure loss of six PSI in two to ten minutes. We also have a low pressure alert which is going to mean that the pressure in our tire is going to be 15% less of the baseline capacity. We also have a high pressure alert which is going to be the baseline capacity is over 20% of its normal. We also have a temperature alert which is something I really like about this system. That'd be particular useful for trailer tires.

Cause one of the main reasons they fail is they get too hot for one reason or another, we're underinflated they're overinflated or we're over weighing the trailer, they can get too hot and then that's what causes a blowout. So we're going to actually have a temperature reading in each of our sensors here that we can display on our monitor. And if that gets out of range, we don't actually have to set that. It's already going to be preset depending on what the PSI of the tire is. So if that's out of range, it's going to give us alert letting us know we need to pull over or slow down.

So something else that our system comes with here, and a lot of people don't like to mess with these because everything is pretty much easy for this installation. For the exception of that one part where we do have to attach two wires and that's going to be for the signal booster. Now we do get a lot of people who don't necessarily have a long setup. They just have a small trailer and tow vehicle. So they don't feel they need the signal booster but you do need to install this, no matter your application if you have a motor home and you're towing a vehicle you even have maybe a Class A, where your set up is pretty long, it's definitely going to be beneficial for you here because we're going to be able to communicate with both these sensors on our motor home as well as the towed vehicle, even if it's a little bit further back than normal.

So that signal booster is really going to come in handy. It does a couple of different things that obviously boost the signal but it also increases the strength of the signal. Now, the reason this is important is because there's tons of wireless devices today on our vehicles and our RVs. So there could be a pretty great chance of interfering or two competing signals, the wireless booster or repeater rather it's going to help improve those chances that we don't have any interference issues. So another nice thing about this system here is that we can actually monitor, in real time on the same screen, up to 22 different tires. Therefore, no matter if you have a motor home in a towed vehicle, you have a tow vehicle in a fifth wheel or a travel trailer, single dual or triple axle. You're going to be covered this system here. Right now, we actually have it set up for a motorhome in a towed vehicle. Our motor home has a dually axle. So you can see we have our front two tires up here. We have the rear outside tires and then we have the rear inside tires. And then we have the four tires on our towed vehicle. So no matter what your setup is, whether you have duly tires on the toad trailer, that's even a possibility as well. We have dually tires on the towing vehicle. We're really going to be covered. We're going to be able to set all these pressures and set them up in the right location. So they're easy to read and we know which tires have what PSI. So a question we get about a lot of these TPMS systems is in regards to towing different trailers or removing a trailer from a vehicle or in this case a motor home that we have now. So say we're going to unhook our towed vehicle and want to drive around in our motor home but we don't want any alerts or readouts from the towed vehicle which we don't obviously have behind our motor home here. We can actually disconnect these four bottom sensors here or you can disconnect however many tires you have. We can actually go into a separate mode here which is going to be the disconnect mode. And we can actually clear these four tires here that represent our vehicle towed behind our motor home. We can clear those out of the system so we can just display the ones here for our motor home tires where we're just in our motor home. So another feature that this system has it's a question we get quite often. So we're in our motor home now and we have our towed vehicle hooked up behind us. We obviously have the pressure readings on the display here. So let's say we want to drive our motor home without the towed vehicle attached, but we don't want to display the tire pressures for that towed vehicle. We can actually disconnect these from the system entirely. So we're just displaying the motor home sensors. So, so far we've been using our little handheld monitor here which is nice. It's durable, it's easy to read, has a color display. We have these buttons at the bottom here. However, if you don't want to use this maybe you already have your phone set up in the dash here for one reason or another, whether that be for music or navigation, and you want to use your phone to display the PSI readouts as well as the alert you can actually do that by downloading the free TireMinder app. So the TireMinder isn't the only TPMS on the market. There are several we actually carry a couple of different brands and I've worked a little bit with each of these. However, I have to say I really liked this TireMinder system here. Not only is it compatible with this handheld device, as well as Bluetooth, I would say the ease of use and installation, I'd definitely give the edge here to the TireMinder. It's one of my favorite systems I've set up so far. Everything is pretty seamless. It's pretty easy to understand and learn. You do want to go ahead and read over the instruction manual but everything's pretty straightforward, nothing too complex. So in regards to mounting, in our kit here we're going to have this nice little bracket here that comes with a sticky slash suction cup mount. There's a little ball and socket joint on the back. And then a magnet that attaches to the back of the monitor. Now, granted, we don't necessarily need to be looking at this thing constantly. It does have an audible alert. So even if we just set it in a cup holder or something we will still be able to hear it go off. But if you're one of those people where you do want to look at it all the time, or have it in your field of view you can easily mount it up on your dash somewhere. Chances are if you have a motorhome, you probably won't be able to use the windshield mount portion of this. But if you have a truck you could probably mount it there. They did in our motor home here I just went ahead and cleaned off the dash surface and just mounted the sticky mount straight to that. So you can see here we have a magnetic mount on the back of her monitor. We can use to hold it while it's not being used in our kit here. We're going to get this nice little carrying case. This is also where we're going to keep our extra batteries for our sensors here. Now you're going to get a few extra that come with your kit here but we do obviously sell some extras here through each trailer as well. So there are a couple of different versions of the A1AS. In order to choose the right one, you need to know how many tires you're going to be monitoring. So we've installed this particular one here. It's the 10 sensor version because we had a dual axle motor home in a towed vehicle. It is however, also available in a four sensor version as well as a six sensor version. And we can always add additional sensors are sold separately as well. So the first step of our installation here we need to install our signal repeater. Now I'll go ahead and answer a question now that we get frequently. Yes, you do have to install this thing. No matter how long or short your RV is, it is required for installation of the system and for proper functioning. However, to install it, it's pretty easy. We just need to find a constant 12 volt power source. But what I mean by this is the circuit needs to have power at all times, even without the keys in the ignition. So the first place I checked on our RV here is going to be the battery charge line circuit on the seven way we want to appear to be installed as far rear to the RV as possible. So the seven way trailer connector is obviously going to be at the very rear. And we do sometimes have constant power there. This particular one, that circuit was keyed meaning it only gets power when the keys are in ignition therefore that's not going to work with us. We went ahead and checked all the rear cargo Bay doors to see if there's any lights there. We could use that to splice into as well. This thing doesn't draw much power at all. So we really don't need a really heavy circuit. So the next step would be to find the house batteries. Now the house batteries this is going to vary depending on your motor home. They're really placed all over. Usually under the cargo Bay doors under the rear there. Ours are actually going to be under the stairs here. So again, these next couple of steps can vary depending on where your batteries are but ours are just under this panel here. So now you can see, we have our three house batteries here. We're going to simply use one of them. It doesn't matter which here's the positive side. Here's a negative side and we have two wires coming from our repeater here. We have a red for positive and black for a negative. Now, if you want to make this real easy on yourself, you can actually just hook these up using the alligator clamps to the terminal on our battery. However, we're going to opt for a little bit more of a permanent installation. Therefore we're actually going to cut off these alligator clamps and we are going to be installing a ring terminal. Just to note for you guys if you do want to use a permanent installation method you'll have to pick up a couple of ring terminals. We do sell some here at each trailer, or you can get them at the hardware store, pretty common part but they're not going to be included with our kit here. So just so we don't get confused, once we have the power wire one attached, we'll go ahead and attach it to one of our batteries. And now we'll just repeat that same process here. For the black, which is going to be for the ground and the negative terminal. So once we have our power and ground wires connected we should see the green light here on our signal repeater. So the next step is going to be to mount this. So again, we want this on the underside of the vehicle if possible, we want to as far back as possible. So our house batteries a little bit further towards the front than I would have liked. So we're going to be using the entire length of this wire here. We're just going to run it far back as possible. And then we're going to, again mount it to the underside of the RV here. Keep in mind this housing here is weather proof. So we're not going to have any issues for it getting wet. So I'm just going to go ahead and drop this down in the frame now, and then we're going to run the sensor as far as it allows us to with the wire that we have, then we can mount it up. We'll show you that part next. So you can see, we have our signal repeater mounted. We just use a couple of self-tapping screws here and secured it to one of these metal panels underneath our RV here. And then we just have the wiring secured to an existing wiring harness running down the frame there. And then the other end obviously attached to our house paddler here. So we had it reached as far back as we can and we just installed it right here. It is sorta a little bit far forward more than I would have liked, but again we didn't really have an option here with our RV because they house panders are under the steps but it's not too long of an RV. So it should be good. But again, just to reminder, make sure we get this thing as close to the rear as possible. So our next step is to begin installing our batteries into our transmitters here. Now we're actually going to have some extra batteries in our kit, which is nice. We do obviously sell these separately as well in case yours run out or you just want to pick up a few extra but it's super simple to install these batteries. Just take one of our transmitters out, unscrew the cap. Counter-clockwise take one of our batteries here. The smooth side is going to be facing up. There's a little slot in there. Just simply press that in like so and we'll re screw on the cap here. Pretty simple, tighten it down, not too tight. It will just repeat the same process for our other transmitters, depending on how many we have. So now we're going to turn on our monitor here and we should see this screen that reads a monitoring. What we want to do is we want to go ahead and take the top and bottom arrows here at the bottom. We're going to hold these both for five seconds. and now we're going to see the learn screen. So this is basically going to let us know which position we're going to be installing our transmitters in. So you can see here we have multiple different positions here which are those two dash lines. Right now, it's going to be preselected for the front left. So what we're going to do is we're going to go ahead and take one of our transmitters here. We're going to go to the driver's side front tire on our RV here and we're going to install it in that position. Then once we screw in the transmitter, wait five seconds we should hear a beep. And then it should give us the readout display of the PSI in that tire. Now we can actually rotate our tires here or not rotate rather choose a different tire setting by pressing the up and down arrow you can see, or on the passenger front here. You can see it just going through these steps here. So we're going to go ahead and learn all of our transmitters now to each of the selected tires. So now we're going to come over here to the driver front tires, we said. We're going to remove the cap. We want to pay attention to the material construction of our valve step. So in our kit here it's going to come with our brass sensors, meaning the insert here that screws onto the valve stem is going to be a brass construction. Now this is going to work for the majority of valve stems out there. There is however, one time that this won't work with and that's going to be if you have the aluminum valve stems if you have aluminum valve stems, most RVs you're not going to have to worry about this. There's actually only a couple select towed vehicles that would have the aluminum valve stems. TireMinder does offer a separate sensor here which you can exchange for the aluminum valve stem. We do sell this separately as well. So you want to make sure you don't have aluminum. And if you do, you'll have to purchase the aluminum sensors. But for the vast majority of the applications you don't have to worry about this. I just want to let you guys know ahead of time. In order to be sure that we don't have any issues of cross-threading. It might be a good idea just to go ahead and clean off the threaded part in the valve stem here. Also not required but if you have it, some dielectric grease here it'd be a good idea to go ahead and put those on the threads as well. Just needs a little bit. Now we can go ahead and screw on our sensor. So we should start to hear air escape. And then once we have it tight, it'll close. As you could see now we have our tire pressure readout for that front driver's side tire. We're going to cycle over to the passenger side, front tire. And now we'll just repeat that same process. So now that we have our front two sensors installed, We'll go ahead and move on to the rear too. Now there's going to be a couple of different things that we need to make note of. This next couple of steps may also vary a little bit depending on what motor home you have. It's not going to be the same for everyone but we've got a dually here. So we have an outside tire and then an inside tire. We're going to be installing the sensor for the outside tire first. So depending on how hard yours is to get to, ours is sort of tucked back up under this little pocket in the wheel here. We're going to go ahead and remove this cover because it's going to make it a little bit easier to get to that valve stem. Now, again, these next couple of steps could vary, but most of the time to remove this cap here, you're going to have several of these little lug nut covers. There's only a couple of them that are actually threaded. If you just feel them, you should be able to feel a little indent there that lets us know that there's a threaded one. Out of all these on here, there are only two that are threaded. So I'm going to be taking a one-on-one ancient socket. We're going to go ahead and remove those threaded covers. Well, go ahead and remove one of those all the way so we can show you there's that little divot that we we're talking about. These other ones are actually smoothed and they're actually not removable So you can see now that we have a little bit more room we should rather easily build to go ahead and screw on our sensor So we'll go ahead and verify the GRI out on our display. And then we'll hit the up arrow to move on to the one adjacent to that one which is going to be for the inside tire. So this brings me to another thing I need to make note of it's valve stem extenders. So the majority of the time you're not going to be able to reach the valve stem on the inside tire cause it's tucked away there. So a lot of people have these Val stun extenders. Now there's a couple of issues you can run into while using these with the tire pressure monitoring systems number one, they must be pressurized. So there's two different types of valve stem extenders. There's a non pressurized type and there's a pressurized type. The pressurized type essentially means that the tube or the body of the valve stem extender is pressurized. Meaning as soon as you screw it in the air is going to come all the way up to our inflation valve here. So you need to make sure that you have the pressurized valve stem extenders. And number two, ideally we would be using a hard valve stem extender meaning it's a one-piece solid metal. Here, we have the braided valve stem extenders which can be used with this kit here. They're not the best, ideally because sometimes they can just create issues. They wear them around a lot and they can also create leaks. But it is still permissible to use these sensors with the braided valve stem extenders. But if you can, I would opt for the hard metal lines here. But just to note, sometimes this particular setup you're really not going to be able to install a hard line because the valve stem is just tucked back too far there. So even with a pretty long extension you probably wouldn't be able to fit. So in this case, the braided hose is our only option. So then again, we're just repeating the same process for the towed vehicle on the display. You will see a line that sort of separates the coach here from the trailer or the towed vehicle depending on your setup here. So just make sure you're on that second section here for our towed vehicle. So most of our newer towed vehicles are actually going to have an integrated TPMS sensor whether they use a band clamp that wraps around the wheel or there's a device at the back of the valve stem you don't have to worry about any interference between the two systems. So once we have all of our sensors paired we're in the learn mode now, we need to go back to the monitoring mode in order to do this, just simply hold these two buttons at the bottom of the screen again for five seconds. So now that we're back in monitoring let's go ahead and switch over to the final step here which is to adjust the baseline readings. In order to do that, we're going to press and hold the center button for five seconds. As you can see at the top, our inner baseline mode here. The first thing we're going to do is we're going to choose our unit of measurement, whether that be PSI or bar. We're obviously going to be using PSI. Press the center button again. We can cycle between Celsius and Fahrenheit. We're obviously going to be using Fahrenheit. And if we press that button again, we can go ahead and set our temperatures for each of our tires or rather the PSI. So in order to do this there's a couple different things we can do. We can check the tire loading information sticker on our RV or vehicle, or if you don't have one of those, you can actually read this directly from the tire. We'll show you that now. So we're going to come out here to one of our tires. We're going to be starting on the front driver's side because that's what the preset is going to be. Once we finished the temperature setting, that's the one that's going to be flashing that we're going to be adjusting first. So it's going to vary depending on your tire manufacturer but usually when you see the tire size here, you'll see the load range. And if you read the smaller text you should be able to see the cold PSI which for this particular tire is going to be 1/10. So that's what we're going to enter as our baseline reading for our front driver's side tire. So now we'll go ahead and use our up and down arrows to adjust TPSI to the correct baseline, reading of 110 PSI Once we have that selected go ahead and hit the center button. And now we're pretty much just going to be cycling through our tires like we did before. We'll show you guys next when we get to the towed vehicle. So most of your smaller vehicles are going to be 32 PSI. So that's what we'll go ahead and set these two. And this is probably going to be most helpful or it's going to be most likely found on the inside of the driver door jam. You should see the tire load sticker there that has this information. So now that we have all the baseline temperature set we can go ahead and put it back into the monitoring mode by simply holding the center button here for five seconds. And that'll do it today for our look and installation of the TireMinder A1AS TPMS for RVs and Trailers..
