TST 507 TPMS (Cap, 10 Sensors)

This was certainly not the least expensive option, but is truly a case of "you get what you pay for". The system works flawlessly and connectivity is never a problem. We like the rechargeable control module (battery last a long time) because it can be slipped in a cubby for easy access when we feel it's necessary to monitor. Trust me, if you have a tire go out of set point parameters the alert will get your attention immediately. We use the cap sensors on our motorhome and tow car and I like that the way they are assembled with the option to change batteries. Overall this is a great system and we're very happy with it!!!

I loved the color monitor and the ability to set every tire independently. I used it with my motorhome and towed jeep by buying more sensors. it caught a tire overheating due to a brake grabbing and saved the jeep from major damage if not total loss. My new rig has built in monitors but I passed the system on to a friend who needed a good system. Highly recommend!

I purchased the TST-507 with 10 CAP sensors to cover my truck and trailer. At the time of purchase, they were just over $600 with the $55 coupon. Pricey, but so is a new wheel and tire and subsequent repairs from blowouts, so I felt the investment was justified. I have a dually truck and a 24' trailer with tandem axles (4 wheels). Based on other reviews we do not expect to need the repeater, however I will revisit this review if we do. NOTE: Be sure to follow the instructions IN ORDER for easy installation. They are easy to read, but I added some notes to the review that I thought would be helpful. Default setting is for tractor trailer tires (way too high) so the PSI & High/Low pressure alarms had to be set for my non-commercial equipment. DO THIS FIRST. Its nice they provide a guide to set the alarm levels - High alarm is 25% over PSI rating on tire, Low alarm is 10% under PSI rating on tire. Once that is done, refer to the graphic in the instructions (see picture) to determine which locations you wish to pair. I used a highlighter to color in the locations I was going to use. It came in handy during the pairing process. There is no right or wrong selections, just what makes sense to whomever is going to use the display. Make sure to identify the sensors using the supplied sheet of numbering labels. Now pair the sensors either using Option #1 (vehicle not needed) or Option #2 (vehicle needed). I had 9 sensors that paired with no issue using Option #1. The last sensor finally paired using Option #2. NOTE: When pairing a sensor, it is recommended to keep a distance of 2-3ft from the other sensors. Depending on your setup, some sensors are easier to install than others. If you are considering flow-through sensors, make sure you have metal valve stems and enough space to install them. The picture of my display is how it will look once all sensors have been paired, but not installed or in range. This is to show that ONLY THE LOCATIONS PAIRED will appear on screen. If you are missing a location, it did not pair. There are instructions to delete one location or all of them at once if you mess up or want a different setup. I checked the voltage on one of the sensor batteries before installation and they had depleted to just above minimum so I recommend bringing extra CR2032 batteries for the sensors.

After much research, I bought the 507 system with 10 cap sensors—6 for our class C motor home and 4 for the little car we tow behind. You see, 5 years ago during our first RV trip with our travel trailer, we had 2 tire blowouts. The first blowout damaged the wheel well trim and wiring. We wound up replacing all china bombs with Goodyears of a higher weight class. I told myself “never again” so when we bought the class C, our first addition was the TST TPMS. On our first use of the TST system—a trip to the NC mountains—it was a great comfort to watch the tire temperature and pressure increase slightly as I drove and knowing all seemed well as readings never approached the warning levels programmed. The 507 system worked great and as long as it continues to provide accurate readings—comfort, it has my recommendation.

Great support from TechnoRV. This unit came with 2 missing parts, the dash mount and some of the theft protection nuts. Rather than return the unit and order a new one I called TechnoRV. TechnoRV promptly shipped the missing items to me. I then set up the pressure caps and synced them to the monitor. I found that one of the caps did not work. I was leaving the next day on a trip. TechnoRV promptly shipped the replacement cap, via FEDEX, to my next campground. I have set up the new cap and it is working fine. The unit is now monitoring the tires on my motorhome and towed Jeep. This unit replaces a TMPS that I had been using and I like this system much better. The monitor done not need to be plugged in while using it on the road. The monitor displays the tire temperature on the left and the tire pressure on the right. I wish the display was reversed, but otherwise this is a great unit, and I highly recommend it.

The setup was straightforward and easy to program the sensors. We have a 38 ft motorhome and pull an SUV for a total of 10 tires. The system worked fine on a 5K mile trip and startled us a couple of times when the high pressure alarm sounded while driving - I had set the limits too low for our rig up. The enclosed repeater works fine for carrying the signal from the towed vehicle. Well pleased with the system. Negatives: I should have upgraded to the flow thru sensors (my fault). The little wrench in the box was not adequate for dually wheels in our case and during our trip, one of the sensors allowed some air to escape and caused a low pressure alert. The sensor was replaced with a stem cap and the leak stopped - eventually, I applied some Teflon tape to the valve stem threads and this solved the problem. Otherwise, a great product.

Watched the youtube videos before I set it up. I like that the sensors are activated by air pressure and that you can set them up (initialize) them before installing. What I didn't expect was that it takes 5 to 10 minutes for the monitor to recognize the sensors after turning it on. Also if using in bright light, the monitor is impossible to read. We are currently stationary, but I look forward to seeing how the system performs on the road. This is a major improvement over my old TireTrakker system which I also bought from Techno RV about 10 years ago. This review is for the cap sensor system, not the flow through.

So I got my system a few days ago, 10 sensors and color monitor with a repeater. I went to TST Truck YouTube channel and viewed all of the instructional videos. That was so much easier than trying to read the instructions. Once I learned how the programming was a breeze. The installation was fairly easy also. The video on installing the repeater showed an older version with the power connection wires having nothing on the ends. They now come with circular wire connections attached to the ends. While you would think that would make it simpler it did not. Attaching the repeater to the Class A house battery directly would cause a vampire drain when not in use and undoing the battery nut to remove one connector each time would be a pain. My solution was to attach the Neg wire using the battery nut. I then cut off the circular connector on the positive wire and attached a battery clip. Now while in use I just attach the battery clip and remove it when not in use. It would be nice if TST could add a power switch on the unit to prevent battery drain and make installation more permanent. Other than that so far so good. Due to Covid I am unable to get out and test that system on the road so once I am able I will update my review. One thing for those thinking about what system to get, understand that a tire blowout can be disastrous to your RV and/or towed vehicle so do not look for a bargain, look for quality and I believe TST provides that quality.

Bon produit mais j’ai choisi un mauvais modèle car si je dois gonfler un pneu je dois retirer la pièce et après la replacer. Ce qui devait arriver arriva lors de mon départ d’un terrain de camping j’ai constaté un pneu à plat. Il existe de la même compagnie que l’on a pas besoin d’enlever pour ajouter un peu d’air au pneu un peu plus dispendieux MAIS ça vaut le coût.

I would give a negative star if I could . Never gave the correct tire pressure very frustrating and could be dangerous if your not checking it yourself. So if that’s the case it’s not doing it’s job and for that price I can’t justify it
