Review of the TST TPMS RV Color Display ire Sensors

Hey everybody, Ryan here at etrailer. Today, we're gonna be checking out, and showing you how to set up, the TST Wireless Tire Pressure Monitoring System. Whenever you're over the road, you know, with your trailer, or pulling anything behind the vehicle that you're using to tow, or even driving a motor home for that matter, you know, there's already a lot of things to pay attention to, and worry about, to try to, you know, be safe and feel confident whenever you're going over the road. And being able to keep an eye on what's happening with your tires is really important, you know. If you think about it, the tires are responsible for a lot, you know. Those are gonna be the only things contacting the ground, and really keeping everything under control, as far as what your trailer is doing, and things along those lines.

So, being able to monitor the tire temperature and the pressure, really goes a long way. That way, if, you know, let's say you end up picking up a nail, or something like that, and you don't really notice it, this will. And what's gonna happen is it's gonna alert you and you can correct that issue before, you know, you potentially get into an accident, hurt yourself or somebody else, or be stranded on the side of the road. So, having a system like this will definitely be able to help you out and keep things moving along. The way this kit is gonna work is really simple.

It's gonna come with four sensors, and essentially these just screw right onto the valve stems. And they have a lock nut on there to kinda keep them more secure and prevent people from coming up and unscrew them. But with that said, these are gonna sync up with the monitor here and display that information and let you know what's going on. The monitor here is gonna be located inside of your vehicle where you can easily see it. Since this is wireless, one of the things that's really nice about it, is the fact that you can use it for a lot of different things.

So, not only a setup like this, but also what's becoming more and more popular now, is flat towing, pulling a vehicle behind your motor home while you're over the road. And with this being wireless, you can always put those sensors on your flat tow vehicle and keep an eye on that tire pressure as well. Or let's say, if maybe you have a couple of different trailers you like to pull, maybe a camper like this, and then maybe let's say a boat. You can pick up additional sensors, so you could keep your, say, four sensors on this one, and then say, if you have a tandem axle boat trailer, you could put four more sensors on that one, save that into the monitor, and then whenever you're pulling, you know, you could go, okay, I'm pulling my boat trailer, hit it on boat trailer, and be able to keep an eye on things like that too. So, this really kinda opens up your opportunities to use this with a lot of different trailers.

As far as how the monitor is gonna look inside of your vehicle, you have a couple of different options. They give you a rubber little keeper here. You can slide it in there. It actually fits in there pretty snug. And it just works as a dash pad. You could keep it like this, or they also give you a window mount. So, it's got a suction cup on there and you can mount it up to your windshield, or whatever. I was actually playing with this earlier, and it works really good. It's not a cheapie that ends up kinda peeling off on you. So, got a couple of options there, and what's nice is this does not have to be constantly plugged in. So, it has a rechargeable battery. So, if you wanna put it, you know, you're not within the length of the chord's limitations. You know, you could put this thing anywhere that you want, and, you know, use whatever works best for you. So, the way this is going to work, once you turn it on, it communicates with those sensors. And, I apologize if it is a little tricky to see, it's really hard to pick up this display. That's one thing I would wanna change about it, not only on the camera, but it's a little tricky. But, it's gonna run through these tires, and kinda constantly monitor them. And if an issue arises, it'll let us know here. So, we're gonna let it do its thing for a minute. I know we have one low tire, just for demonstration purpose here. So, it should run through and start to find that and let us know what's going on with it. So, I've been keeping an eye on this for several minutes and I can't get it to pop up saying that we have a low tire. I was playing with it earlier and it was working, but now it's just kinda cycling through the tires, so I'm not real sure what's going on, not overly impressed by any means. I feel like it should be a little more responsive than this. With that said, it seems like a lot of our customers have had pretty decent luck with it. Maybe it's just me, but it's just kinda odd to me that I know for a fact one of our tires is indeed low enough to trigger, and sometimes it triggers and sometimes it don't. So, not real sure what's going on with it there. I feel like it should be pretty much automatic, though. As soon as this happens, I feel like this monitor should identify it and let us know. So, I ended up getting it working, and this is what it looks like. It's just kinda being super random about it. So, I don't know if it does a ton of different cycles before it tells you that, or what, but you can hear that audible noise beeping. I'm gonna turn that off. That way we can hear what's going on. So, when that noise does start happening, you're not gonna miss it. You're definitely gonna hear that one going off, and you know, it's gonna alert you that indeed you do have a low tire. It's gonna signal through and let you know which one is which. So, it looks like the left front one, that's the one that's popping up, is the low one. So, once the monitor here is communicating with all of the sensors, this is the display that you're going to see, and it is kind of cycling through each tire. And in our case, all four of our tires are low. This has been sitting for a while, since it's damaged. But with that said, you know, it's gonna display that pressure reading, as well as the temperature reading. And that pressure reading is indeed below our threshold. And when that happens, it'll give you a low pressure indicator, as well as the low pressure tire light I'm sure many of you have seen in your normal automobiles. And so once that happens, you know, it's going to let you know what's going on, and you can stop at the next station and put some air in your tires. Other than that though, I mean, that's pretty much it. It would give you similar indications if you had too much pressure or too high of a temperature. It would just prompt you on the bottom of the screen, and lets you know what's going on there. So, pretty straightforward, cut-and-dry. You know, there are some other things you can do. So, if you hold down Set, I mentioned about adding other vehicles if you got more sensors, and you know, you can do like Set ID Trailer, is what this says. So you could set the parameters to, let's say, the trailer we're hooked up to now. And then if you want it, you know, with a different trailer, you could always go through it through that, and that way you wouldn't have to reset your parameters every single time. So, at first when I started playing around with this, like I said, I wasn't overly impressed with it, but that's kinda partially on me. I feel like I was just a little too impatient. I didn't realize it would take a few more minutes than what I thought for these to actually sync with the monitor. It actually took quite a bit of time, but once it did that, you know, and now we're able to cycle through and actually see how things are working, it seems to be working actually pretty good. So with that said, one of the things that still does hold true is the display. I tried playing with it in several different positions, and things like that. And it can just be tricky to see sometimes. It's either you can see it, you know, super clear, or if you shift your head a foot to either way, it just completely disappears. So, it would be nice to see some improvement as far as that goes. But you know, then again, if you're sitting in your driver's seat, you can kinda maneuver it in that way you need to, and get it as best as you can. Thankfully, if there is a warning, you know, low pressure, or too hot, or overinflated, whatever the case may be, thankfully there is an audible alarm that we heard that goes off. And I mean, you're not gonna miss that When you hear that, that'll allow you to maybe get over to the side and take a better look at the monitor and help figure out what's going on. Nowadays, having a tire pressure monitor system really does make sense. It kinda helps simplify that process, you know, when you're pulling a trailer, a camper, or whatever the case may be, now, there's already a lot going on. And, you know, its' gonna save you a little bit of time during the pre-trip. You know, you're not gonna have to check your tires manually with a gauge, and everything else like that. And I mean, honestly, really, if you think about it, all the late model cars now are required to have that tire pressure monitor system right out of the factory. I'm sure just about everyone has seen that by now. And there's a reason that they mandate that, you know, and that's for safety for out on the road, not only for yourself, but for others, and not to mention too, it can kinda help out your pocket book a little bit. You know, if you have a low tire, and it's not super low, but low enough that you really can't feel it, but what can happen is that tire can wear differently, kinda start to wear at the sidewall. And then you end up running down the road for, you know, quite a few miles, and that tire wears funny. And then you got to look into a replacement, and that could have been avoided by simply just putting a few more pounds of air in it. So really, it's a win-win for everything. Honestly, I don't really know why the factory now for these motor homes, and these campers, and things like that, I don't really know why they don't just equip them right out of the box. It makes sense. It's another vehicle on the road. And if the cars have to have them, you'd think they would too, but that kinda is what it is. But you know, putting one on yourself, you know, you're kinda going the extra mile to ensure that you're gonna keep yourself a little bit safer, others around you, and save a little bit of money in the long run, as well. And not to mention too, just that peace of mind, you know. If you're going down the road, that thought of what's going on back there, is kinda erased a little bit when you can see what's happening in real time from right inside the cab here. To actually get your tire pressure monitoring system installed and working, it's mostly just setting everything up through the display, but there is one or two things that we need to actually get done. And the first one is going to get the repeater hooked up, which is this component here. So this is how I did our repeater. I just used a couple of screws to secure it to the frame of our trailer. Now pay attention, depending on what you're putting this system on, whether it be a gooseneck, or a bumper pole, or a motor home, they do advise you to put it in certain locations. So, check on that whenever you're doing this. And with that said, there's this wire that comes off it. And I ran it up here to our batteries. And pretty straightforward, you simply have a power wire that you're gonna hook to the positive side of the battery, and a ground wire that you're gonna hook to the negative side of the battery. And before we screw our sensors on and pair them, we need to make a few initial adjustment. So, I'm gonna turn our monitor on, and then we're going to hold the Set button down to get the high pressure set. I already went ahead and did our front axle. We'll do our rear axle. To change axles, you can simply hit Go, and then it'll go to the next axle. Now, every setup's gonna be a little bit different, you know, and you can always talk to your tire manufacturer to see what they recommend, but a decent rule of thumb is 25% over the recommended air pressure. So in our case, that's about 81 PSI. So, we'll simply use our arrows over there to set it. Once we have it like that, we're going to hit Set, and then we'll come back and double check it. So, we're gonna do that. And hit Go again. So it verified that. So, you'd simply do that for all of your axles, once that is done, we'll just toggle through again. So, we'll do Low Pressure Set. Hit that, and again, about 10% under your maximum, I'm sorry, your recommended air pressure in your tires. Our recommended air pressure is 65, so 58's pretty close. And, same deal. We'll hit Go, change him over there, that went down a pound, and hit Set. Then we can do High Temp Set. It is recommended just to leave it on the default setting. If you do need to change it or alter it, then that'll be your responsibility. And then we kinda have the basics, you know, set the display type. So, do you want your tire pressure to show in PSI or Bar. It's defaulting in PSI, that's where we're gonna leave it at. And then of course, the tire temperature in Fahrenheit and Celsius. It's defaulted to Fahrenheit, and so we'll leave it there. Then you can toggle down to where it is saying, or flashing rather, Learn ID. We're gonna keep it in this mode. We can grab our sensors and program the sensor to our monitor. Once you're on the Learn ID, you can push Set and toggle through the tires. I already did three of them. We need to still do the right rear, or the passenger's side rear tire. So, you could see, we don't have a code here. What we're gonna do, is hold our sensor to the bottom left corner, hit Set and then hit Go, and then we will get a code there. Once that code is flashing we'll hit Set, and that'll remember that code. So, now every tire that we scroll through here, that we have programmed, will get that different code. So, once you have all that done, remember which sensor goes where. They do give you some stickers you can put on that sensor. And you can, you know, do them however you like. In our case, I did the the driver's side front as one, driver's side rear is two, passenger's side front is three, and passenger's side rear is four. So, however you think you can remember them best, that's how you can do that. And now with that done, we can go ahead and get this actually installed on our tire. So, here at the appropriate tire we get rid of our old valve cap. We're gonna take the brass hex nut here and thread that down just till it stops. Take the sensor, and we'll thread it on. We'll just get it snug, you don't need to crank down on these by any means. And so if it's on there, that hex nut, you just gonna run that up, it kinda acts as a jam nut. So, you'll get that snug, and then you take this special wrench they give you and simply just snug it up just a little bit. And that's really all there is to it to get these on on your wheel. So, once we have all of them on, we'll come back and turn our unit on, and see what happens here. So, the sensors are gonna communicate and let us know if something's going on here. So in our case, looks like we have a low tire, or two, maybe. So, it looks like the front right's good, the left rear is good, but the right rear is shown as low, and it also appears as if the right rear is as well. So plugging this in first thing, you know, I'm sure it's gonna have to kind of make some adjustments here. So, I think what we're gonna do, is go put some air in the tires and manually know exactly what they are, do this again, and see what happens. So, I went ahead and tried to add some air. I had to use a portable type compressor, because we're way out here in the parking lot and our airline won't reach. And unfortunately the compressor, it's a dud, it's not working for us. Can't move the trailer over to our airline, because it has damaged axles, and we don't want to risk, you know, compromising the trailer before getting those fixed. But I mean, with that said, you get the idea, you know, you would put these on and then set your air pressure to the recommended amount. It would change in there. And then you'd have a good, solid baseline to start from. And that'll finish up our look at of the TST Wireless Tire Pressure Monitoring System..

Questions and Comments about this Video

What if I buy the Tireminder i10 system? Do I need metal valve stems with that?

Reply from David B.

As a rule of thumb I always suggest going with a metal stem if you get the flow through tpms just because they tend to be heavier and longer. The i10 flowthrough sensors are not that much heavier than their standard counterparts so if you wanted to roll the dice you could but If I was getting it I would go with metal stems.

Should I be replacing my rubber valve stems with steel stems when I install the TPMS sensors on my trailer? This makes them stiffer and stronger as the TPMS sensor adds weight and thus centrifugal force (when spinning) onto the valve stems and the rubber valve stems might fail.

If you are using TST TPMS for RVs - Color Display - Signal Booster - 4 Tire Sensors # TST-507-RV-4-C then you do NOT need to replace your standard valve stems. If you are using TST TPMS for RVs - Color Display - Signal Booster - 4 Flow Through Tire Sensors # TST-507-FT-4-C then yes you WILL need to get metal valve stems.
