Bellacorp Tire Pressure Monitoring System TPMS (8) Sensors for Truck and Double Axle Trailer, Or RV, Including Repeater

So far I am very satisfied with the Bellacorp TPMS.I have had this TPMS for about a year with several thousand miles on the sensors and device.I ordered the 4 sensor plus repeater for my two axle 5th wheel toy hauler. I have had other TPMS units which all seemed to have issues that cost me money i.e. non-replaceable batteries, no temperature readings, etc. This TPMS is a great COMPLEMENT to good tire maintenance. I physically inspect my trailer tires frequently and will "wake up" my sensors (loosen then tighten) to get the latest pressure readings very quick and easy while refueling. That process will also alert you to battery or sensor problems. One of my other TPMS units would constantly set off tire alarms as batteries would lose power, repeatedly connecting and disconnecting, requiring immediate action to replace batteries or turn the unit off completely until it could be addressed. So far, I prefer the way this unit responds. TPMS should aid with tire maintenance not be used to replace the physical inspection. I also remove and replace the sensors when the trailer is parked for long periods without use.

As advertised! Customer service could be better

UPDATE: I am adjusting my review from 5 stars to 3 simply because I've lost some confidence in this system. I still believe it is one of the better systems on the market, but I've lost it's trust. I haven't owned this very long and about 4 times now I've noticed one or two tires "lagging behind" on the readings. First time it happened I didn't think it was a big deal. With 4 tires all matched on PSI one would expect the PSI and temps to increase when pulling at approximately the same rate. When one gets off by 8 PSI over the other 3 or temps are 8-10 degrees off you kind of wonder after a few times. Then 20-30 minutes later it 'magically' jumps up to the other 3 and then they are similar. Well during this time frame I'm guessing the system is losing it's connection to that wheel/sensor and not updating. How the system works is it just displays the last known good signal and keeps displaying it FOREVER, even if it doesn't receive a signal.Try unhooking from your trailer and drive around without it. Yep, it just keeps telling you the PSI and temp of the trailer tires the whole time, even though it's not back there!! This is a huge problem in my eyes, and unfortunately it's not likely to get fixed as the system can't be updated via USB or other remote means I don't believe.I was hoping this was a "set it and forget it" system and it will alert me if there is something wrong. I know it can't prevent all tire mishaps like blowouts, but to me the system should display a blank or no read signal if it's not getting it from a sensor (at least after 5-10 minutes of lost signal) Yesterday I noticed a couple times where temps and PSI would stay the same for long periods of time, even though others were moving a bit. So now I sit and watch the system to see if they change every 5-10 minutes, which is distracting, otherwise I'm pretty sure they are losing signal. This is even more discouraging when temps and PSI get up to normal increases after travelling then lose connection, so it's hard to recognize when there is a loss.I'm not trying to bash this system and I'm not complaining, just stating the facts that it will display the last known good signal for a long time even though it's not getting updates. If I have something mis-configured please let me know. I have reprogrammed the sensors and it hasn't made a difference.It's better than nothing, but unfortunately not a 5-star product for me anymore.OLD:Using this system on my 2500 truck and 5th wheel camper tires. Installation was super easy, just follow the instructions. I've had zero issues so far. Takes just a minute for all to be recognized when starting up. I really like the alert features, I like how you can "disconnect" the trailer tires on the display when not towing, and I like how it has a recharable battery. I haven't had to plug mine in yet and the battery still has 3 bars. No cords unless charging. I hope these units will work when really needed, however they can't prevent blowouts and unfortunately they are common with cheaper camper tires. If there is ever a slow leak or heat build-up I feel these will work great. Hoping for many years of service out of them.

Right up front: I like this system and am very happy with my purchase.As an automotive executive, I am very familiar with the value of a TPMS system. I wanted to add a system to my camper to improve towing safety. I researched many reviews finding that the Bellacorp system was consistently mentioned as one of the best systems. While I suspect many of the systems would perform adequately, what sold me originally was the fact that the company has included a repeater (previously a $50 option) due to their concern that the frequency utilized is getting crowded and they want to ensure solid performance - this told me a lot about the company. The repeater was simple to install if you have even basic skills.There are fancier systems, and systems that have more elaborate screens, etc., but I was looking for simplicity and solid performance. The instruction manual is clearly written with significant detail providing excellent documentation of all of the features and options. The setup was simple, fast, and easy. You screw on the sensors, mount the monitor, and you are in business. You can alter all sensor alarm settings to be as sensitive as you wish following the well documented manual.I tested the accuracy of the pressure sensors with a NIST-traceable pressure sensor and all sensors were spot on, and well within their tolerances. I didn't test the temperature sensors, but all of the sensors accurately measured the ambient temperature of cold tires, and tracked consistently during towing. I checked the alarm sensitivity by removing each sensor, and was rewarded with a nearly instantaneous alarm.If you are looking for a simple, accurate system with excellent performance at a reasonable cost - look no further. The Bellacorp system met every one of my expectations, and as they are concerned enough with meeting performance expectations to throw in free options, I can see why they are consistently considered one of the top systems around.

Having tire pressure and temperature will put your mind at ease. I do not have to worry about a tire on my trailer or truck going low unnoticed until it blows and does massive damage to my enclosed car trailer or truck for that matter. The temperature feature is also awesome. If a wheel bearing or brake is getting hot, you will know before it does catastrophic damage. I have had this system for 2 years now, and appreciate the peace of mind it has given me.I bought this system in 2017. It has worked great for me. I the 5 years I have had it, twice I had trailer tires going low and the system has alerted me so the tire did not go down and blow. It very well has saved having major damage to my trailer because of early warning! Mine is the earlier design system and has been trouble free for me.

Easy fit, just remember to Follow the Directions and it will work.

they work awesome
