Review of the TST RV TPMS Flow Through Tire Sensors


Shane: Today we're gonna be taking a look at TST Tire Pressure Monitor System for RVs.Hi, I'm Shane with etrailer.com. Here we have one of several different types of tire pressure monitor systems. What a tire pressure monitor system is gonna do, it's gonna allow you to monitor the tire pressure on your trailer, whether you're pulling a trailer behind an RV or a car behind an RV, or you're pulling a trailer behind your truck when you're traveling. This is gonna allow you to monitor that tire pressure from inside the vehicle.This kit is going to include six flow through sensors. These are gonna mount to your tires, and they're gonna send a signal to your monitor, so you can monitor the pressure from the inside of the vehicle. A wrench, locking nuts.

The locking nuts are gonna be put on underneath your sensors, and it keeps your sensors from being stolen. You have your monitor, which is gonna display all of your tire pressures. You're gonna have a rubber stand for your dash, you're gonna have the charger cord and the charger for your monitor. You're gonna have your repeater; what the repeater's gonna do is that helps strengthen your signal between your vehicle and your tires on your trailer. You're also gonna get an additional windshield mount as a second option to mount your display.Now the thing it's gonna come with, it's gonna come with some stickers.

These stickers are gonna go onto your sensors so you know which sensors go on which tiers. Our four sensor and six sensor kits, along with our two sensor and four sensor sets, are all gonna come with this sensor here. This is a flow through sensor and what this allows you to do is it allows you to leave this sensor on the valve stem to inflate it and deflate it. There are other types available, like the one I have here. It's all gonna have all the same functions, except you're gonna have to remove it any time you wanna inflate and deflate the tire.

Now if you prefer this type of sensor, the kits are gonna be exactly the same with either the four or the six. Then you can add on either the two or the four pack.As far as programming our sensors to our screen, we need to do that before we put them on the tires. To start, what we're gonna do is we're gonna number our sensors. Once you get them all numbered, as you start syncing them separately, we're gonna sync one at a time to our screen. You wanna take the additional ones and put them at least two feet away.Now, to set up our first sensor on our monitor, we need to turn our screen on.

It's gonna be right here on the right side. This is gonna be our main screen. This is gonna be our truck, this is gonna be our trailer. We're gonna hit the set button, we're gonna hold it down. You're gonna see high pressure is set and blinking, press the plus or minus button and scroll through. We're gonna go to learn ID. When you see it blinking, press the set button.You're gonna notice six Fs. Again, truck and trailer. You're gonna notice that the front wheel is blinking. What I'm gonna do is I'm gonna scroll through until I get back here to my front driver's side trailer. We're just gonna do that by using our plus or minus. Just like that. We're gonna hit the set button. You're gonna notice three, the Fs are blinking. Set our sensor next to our monitor. We're gonna hit the go button. Gonna display a number, that's the number for the number one sensor. We're gonna hit set. It's automatically gonna set that sensor for that tire.So now what we need to do, before we add our sensor onto our valve stem, we need to back to the main screen. We're gonna press the back button. Press the back button again. It's gonna display our temperature, it's gonna show that tire blinking, zero PSI for our sensor. If it beeps we're just gonna push this top button; that'll get the beep to go away. We're gonna take our sensor, gonna make sure it's numbered to match our screen, and we're gonna screw it on just a little bit. We don't wanna screw it on so far that we hear it hiss.Once we get that on, we're gonna hit our set button, and we're gonna hold it til it beeps; we want to go, or scroll through to set ID, or learn ID. There, we're gonna hit set. It's gonna show our Fs, and scroll to our tire that we have the monitor on. It's gonna come up with our code. We're gonna tighten our sensor all the way down, and we're gonna press the set once.Once we get our first sensor loaded, we're gonna go back to the main screen. Press back twice, it's gonna show zero PSI. We're gonna screw it onto the valve stem; you wanna make sure your monitor is close. It's gonna show you your temperature of your tire, and the PSI in the tire. You're gonna repeat that process for the remaining wheels that you're putting sensors on.Now I'm gonna show you a second way of getting your sensors installed on your screen. We're gonna go back to the same screen we were, press the set and hold it. You see your . we're gonna go to learn ID, press set. We're gonna get the six Fs. Hit your plus or minus to take it to the tire that you're gonna be adding, it's gonna be our right tire on our trailer. Now we're gonna take our sensor and we're gonna lightly screw it onto our valve stem. We're gonna screw it on just enough to where it's holding it, we don't wanna screw it on so hard that it's . you can hear air hissing. And what we're gonna do is we're gonna hit the set button to where our Fs are blinking, and then we're screw our sensor on all the way.You wanna make sure that your screen is close to your sensor; and you can see it's reading it. We just press the set button. Now that tire is set. We're gonna repeat that same process for the other remaining sensors that we're installed on the tired.So now we're gonna show you a second one. We're on the other side of the trailer, front wheel, so I'm just gonna take my plus or minus, go to that tire. You have to screw it on just barely. You don't wanna hear the air hiss out of it yet. We're gonna push set button once til they blink, screw it on. It's gonna bring it up. Press the set button, that locks it into place. Now that sensor is set. Repeat that for your remaining tires.Now we're gonna have different alarm settings on here. We have temperature settings, or temperature alarm settings we can set. We also have PSI settings, low pressure and high pressure settings. Again, if you notice a tire blinking, that's telling me what PSI I'm set at. If I set a low pressure . my tire pressure's supposed to be at 72, and I set a low pressure of say 65 PSI. When that pressure gets to 65 or below, my PSI is gonna blink along with my tire telling me that that tire is low, and I can set that for each axle, however many tires I have.So our highest pressure's 72, lowest pressure's 71 on our tires currently. What we're gonna do is we're gonna go in and I'm gonna show you how to set our pressure reading, our low pressure reading. You're gonna hit the set button, you're gonna hold it. You're gonna see high pressure set, low pressure. Hit the set, it's gonna show PSI. You notice two tires are blinking; it's gonna set your pressure per axle. You press the go, that's how you're gonna change the axles.This is gonna do this per axle, not per tire, because you don't want one way higher than the other. We'll press set, we'll go up to 73, which is above where my two tires are now, press the set. Hit the back button, and you can hear it beeping. What it's doing, it's telling me that the tire pressure on this, and it's showing me the tire blinking and the pressure, is lower than what my lowest tire pressure setting is. To silence your alarm, you just hit that top button there. You notice it's blinking, along with the tire. It's telling me the tire pressure is too low, I need to get air.So now I'm gonna show you how to set your high temperature reading. So I'm gonna allow you to do the high temperature reading because our tires being cold is not really an issue. We don't want our tires to overheat.We're gonna hit the set button and hold it. You can see high pressure and low pressure again. Hit our plus or minus. That'll scroll through, you're gonna see high temperature. You're gonna hit set. This is gonna allow you to set your temperature at whatever temperature, the high temperature you want your tires to be at . or the highest, I should say. And then once you get to your whatever reading you want, you hit your set button, it'll hold that temperature at that. It won't let your temperature go above that, and then it'll start beeping like it did with our tire pressure.You also notice the bar PSI setting. You have your temperature settings here, fahrenheit and celsius. Your tires. It's gonna tell you which tire . this is gonna be number two. You can do up to four trailers, or you can hold up to four trailers. So if you have multiple trailers that you tow, that you have sensors on, all you gotta do is switch to which trailer you're on and you can automatically, it'll automatically tie into those sensors that are on that trailer.You can set your truck ID, or ID for your truck if you have a truck, and your trailer, you can set your tires . or your sensors for your truck, and your trailer. And then adding your sensors is just the same way that we just showed you for either the truck or the trailer.We're gonna go ahead and install a repeater. For demonstration purpose I'm not actually gonna bolt this to the frame of our trailer. This can be mounted inside or outside, it is fully waterproof. You just wanna make sure you hook it up to a 12 volt source, and you wanna make sure that it's gonna be powered while you're driving. You want it to be in between the tire pressure sensors and where your monitor is in the vehicle, or in your vehicle while you're towing.You wanna try to have it as far forward on the trailer as possible. It can be mounted to the vehicle if you prefer to have it mounted there. What I would do is I would just pick up a second sensor, if I had multiple trailers, and mount one to each one of my trailers myself.So now, what we're gonna do is we're gonna hook it up to our battery. It's a little cold out, so my wire's a little stiff. The ring terminals do not come with your kit; you can find them here at etrailer.com, they're just 10 to 12 gauge ring terminals. Just whatever size terminals your battery has, you just wanna make sure the ring terminals are gonna fit on it.So you'll notice our light on our sensor is red. When it's solid red that means it's working correctly; you might see a blink every once in awhile, but as long as that light is not blinking constant, you know it's working correctly. What this is gonna do, this is gonna strengthen your signal from your sensors to your monitor while you're driving.As we're sitting in our truck, you can see it's reading the temperature and the tire pressure for the two sensors that we have installed on our trailer. This is telling us that it's reading those, and it's gonna read it as we're traveling. So we'll be able to monitor all of our tire pressure and our temperature.Then we're gonna have a couple different ways to mount it. We have our rubber stand that we just sit up on our dash just like that, or we have the optional window mount. If you notice on the back of our screen, and the back of our mount, is gonna have little tabs. We're just gonna take that, and we're gonna slide it, and we're gonna push that to lock it in place. Take our window mount, inaudible 00:13:48 push, and we're gonna lock it into place. This is gonna allow our gauge to hang from our windshield, but we can put it anywhere on our windshield, you just wanna make sure it's not covering your view of the road.Now, our monitor is battery operated. You'll notice the battery here on the left side of the screen, but it is rechargeable. The battery in it is a lithium battery and it's non-replaceable, so just keep that in mind. It is gonna come with your charger, your car charger, and your cable. It's a USB cable. We'll plug our charger into our 12 volt power source, and the other end into our screen. And we'll see right here, it's charging.As I've mentioned before, your kit's gonna come with some nuts, and a wrench that's gonna look like this. This setup is going to work better for these rather than the flow throughs. You can see the tap spins here. How we're gonna install these . when you install these sensors, you're gonna put the nut on. Go all the way down. Then you're gonna take this guy here; you're gonna have to have the wrench to install these. Get this on. Then what you wanna do is you wanna tighten the nut up against the bottom of the sensor. And what that does is it keeps somebody from coming by and stealing these off, because they can't get it off without this wrench. You can see our cap just spins.Let's say you're wanting to delete all of your sensors that you have programmed on your monitor. You're gonna press the set button and hold it. You're gonna go to learn ID. We're gonna go to our sensor there, first one that comes up. We're gonna hit the set button. We want that to blink. We're gonna hit the back button and we're gonna hold it. You're gonna hear it beep three times, it's gonna go to three Fs. Then it's gonna come up and it's gonna say, "Delete all." It's gonna beep six times. We'll hold it. It deleted that one. And you can see it says, "Delete all." It's gonna delete everything you have on the screen. So we press select, and now you've just cleared out all sensors that you have installed on there, and you can either start over, put them in different positions, whatever you choose to do.That'll do it for a look at the TST Tire Pressure Monitor System for RVs.
