TST Tire Inflation and Repair - TPMS - TST-507-FT-6-C Review


Today we're going to take a look at the TST tire pressure monitoring system for RVs with the color display, the signal boosters, and the six flow-through tire sensors. Now this TPMS kit will let you monitor your RVs tire pressure and temperature with the included full color LCD display unit. It does work great with your motor home fifth wheel or trailer.The display is a nice full color wide screen display. Provides early warning detection with visual and audible alerts. And just to show you what the display looks like, we're going to go ahead and zoom in some so you can see it better. And then I'm going to go ahead and turn it on.

You can see with it turned on there's a good full color display. And then it goes to settings.Now this display will detect blowouts, significant pressure changes, and tire temperatures exceeding 158 degrees. And it does refresh automatically with new tire information every five minutes. I just want to show you if you hold down that middle button, that's to set your settings. It will beep, and once it beeps now it's ready to set.

You have your plus and minuses here, and it takes you through all the settings you can set. The pressure you can set are psi or bar. Temperature set is Celsius or Fahrenheit. And I just want to turn it back on again to show you what it looks like.Now the sensors, it gives you six sensors here to check the tire pressure and temperature. These are a brass construction.

They are designed for use on rubber, steel, chrome, or nickel valve stems. And these sensors do install easily on to your tire's valve stems.I happened to pull a rubber valve stem here, and just to show you how this install now. It is a theft-resistant design, so it does require the use of these cap wrenches. And I'm going to show you how they work. Basically what you would do is here's your valve stem.

They give you these four lock nuts, brass lock nuts. That you'll first put the lock nut on to the valve stem. And then you take your flow through sensor and just go ahead and turn that on. And you tighten that and you just tighten it all the way until it seals and then run up the lock nut. And then what you want to do . These are the cap wrenches. They include two of these.You notice what you do with these, it will wrap around the valve stem and go over the nut. And then you just tighten it even more. And once you get it tight enough, it'll lock it into place and then nobody can take these off. In other words, somebody will see these and think they can just unscrew them but you can't unless you unloosen that. And you really need this cap wrench to do that.I'm just going to go ahead and back out some here. And then to remove it, again you take your cap wrench, put it on there. And then you just loosen that nut, and once that loosens back it off. And now you're able to take off your sensor.Now these sensors, they are a flow-through design. So when they are installed on to your valve stem, they will allow your tires to be inflated or deflated without having to remove the sensor all the time. You can just go ahead and take the cap off here and then put your air through there or release your air out through there. So it's a nice flow-through sensor.Now this bag right here that I have these lock nuts in, they also include some screws and O rings. Basically they include these extra screws, washers, and O rings because the battery that's in these sensors, if you do ever need to ever replace one, there's two screws here on this side that you can remove, take your battery out, put a new battery in, and then just put your new screws in and your O ring to seal it. So they do give you extras of those.Now the monitoring capacity with these included sensors will be six tires. Now we do sell additional sensors separately on our website. It will let you monitor up to 38 tires. So this display, you could add up to 38 tires to display on this. And it sounds like a lot, but what's nice about it is all the extra sensors you purchase, you could put those on different vehicles. Put them on a motorhome, your trailer, your fifth wheel, and then you could all use this display to monitor them all.Now it does include these display mounts to allow for optimum positioning of your monitor. It first has the nice, easy-to-use suction cup for your windshield or dashboard mounting. That basically will just stick on there and latch into place. And then you can rotate it up or down. Just like that. And then the other one you can loosen and it will go side to side. So you can put it in whatever position you need. If that doesn't work for you, they do also offer this cradle mount to put on a flat surface. You can put it on a flat surface and it's made to where it doesn't slide. And then you can just push that right in there. It holds it into place.Now the repeater, or the signal booster, this will strengthen and amplify the sensor signal forward to your display. It eliminates electronic interference. Right here there's a red light that will light up when it is working. And this unit is waterproof. Can be mounted inside or outside. And it does mount with the included screws.Also includes this micro USB cable and adapter. It's all included for charging with your vehicle's 12 volt outlet. Just plug that into your 12 volt power, put your USB in there, put the other end into there, and it will charge your display. Now this monitor does use a rechargeable lithium battery.A few specs on the monitor. We'll start with the run time is five to seven days on a full charge. The battery recharge time is about four hours. A few dimensions on it. Overall width of it is right at about four and a half inches wide. Height all the way up to the top of the antenna is right at three inches tall. And the depth on the unit is about one inch deep. Now the screen itself is going to be three and a quarter inches wide and one and 5/8 inches tall.The tire sensors, they give you six of them, the pressure range on the sensor is 0 psi to 196 psi. Operating temperature range is -40 degrees Fahrenheit to 170 degrees Fahrenheit. Storage temperature range is -40 degrees Fahrenheit to 185 degrees Fahrenheit. Battery life that's inside here is about one to one and a half years. I did mention you can replace them. They give you the extra parts to do that.Now the battery it uses, you'd have to buy separately. They are CR1632 size. And the dimension on the sensor itself, you're looking at about two and 1/8 inches long, about 7/8 inches inches tall, and about one inch diameter. And on the repeater, that is going to be about two and a half inches tall, three inches wide, and about 5/8 of a inch deep.It does come with a nice owner's manual that will describe how to hook this all up, and how it operates. But that should do it for the review on the TST tire pressure monitoring system for RVs with this full color display, the signal booster, and the six flow-through sensors.


Questions and Comments about this Video


Lee F.
I often pull a UTV on a trailer behind my 35 ft 5th wheel. It looks like I need about a 55 to 60 foot range between my dash and the two tires on the back trailer. What is the range I can expect with the TST 507rv TPMS

Reply from Jon G.

It should work just fine but you'll want to install the transmitter towards the rear of your 5th wheel. Attached is a link to a Q&A page that goes into this as well.
