I have had my Bellacorp Tire Pressure Monitoring System for about 3 years. Previously I had another tire monitor system that required sending the sensors back to the factory to replace batteries. That would have cost more than the purchase of a new Bellacorp system with user replaceable batteries. Upon receiving my new tire monitoring system, it was obvious that the Bellacorp product was top notch quality.

The initial setup was a little confusing because of some errors in the manual. A separate sheet with correct instructions was included in the box. Once I read that, things became clear. A friend of mine recently purchased the same system that I have and I noticed that the manual has been re-written.

There must have been a bad batch of sensors because over the first six months all of the sensors failed, a few at a time. Bellacorp stood behind their product and replaced the sensors promptly. Since then all of the sensors have performed well. I have two that read slightly high but I am aware of it and can take that into consideration while taking readings.

This system saved my bacon on two occasions when fast leaks developed due to cracked valve stems. I was able to safely pull off the road and change the tires before they went completely flat. I have since switched over to metal valve stems and have not experience any more problems.

I love the fact that the batteries are user replaceable but found the CR-1632 cells can be difficult to locate locally. I purchased a 10 pack on Amazon at a very reasonable price to have on hand to use as needed. I just replaced two (which prompted me to finally write this review) and have five remaining.

I am very satisfied with the Bellacorp system and recommend it highly.

I bought this to monitor the tires on a large gooseneck trailer and decided to buy four additional monitors for the truck. It worked well on my initial 2,500 voyage and paid for itself within the first hour by spotting a quick leak in a rear trailer tire. I had just put on a new set of Michelin tires on the trailer and the tire shop failed to put on new valve stems. One of the valve stems began leaking after the first 60 miles and the Bellacorp gave an immediate warning of loss in tire pressure. I pulled over and changed the tire - probably saving it.

The trailer is a 32' gooseneck and their were no issues with the receiver getting a good signal on the truck or trailer monitors. It provided real peace of mind on a long trip to know that all the tires were operating as intended.

The only issue I had was the instruction manual. It shows three different ways to register each monitor with the receiver, but was not clear that you could use any of the three. The manual method of putting the receiver next to each monitor worked fine. The monitors work great and the receiver cycles through each one, showing the PSI and temperature rating of each tire.

Highly recommended.

I recently replaced the tires on my tandem axle Airstream travel trailer. The tire shop replaced valve stems along with the tires. Unrelated to the tire change, I added the Bellacorp TPMS before taking a planned 3,000 mile trip. Two days before we left I took a shakedown cruise. It was the first time the tires rolled. Within 5 miles I had a TPMS low pressure warning. Long story short... all four valve stems were leaking. The shop replaced them (I now recommend full steel stems!). The trip went as planned. I'd say the TPMS saved me from being stranded on I-95 in August Florida heat... or worse. During the first part of the trip I experienced intermittent loss of signal from the sensors. Bellacorp tech support was great. I added a repeater at Paul's suggestion. Many Airstream owners determine repeaters are needed regardless of which TPMS system they use, so I didn't see that as a Bellacorp issue. 2,000+ miles later, I'm a happy camper! One more benefit... I've always felt my Airstream dealer may have set up the hitch system with the trailer a tad low in the nose. The TPMS showed both front tires heating up 3-5 degrees hotter than the tires behind them. That's just enough to have me revisit the hitch setup and probably raise the ball an inch or two. That's was an unexpected benefit of closely watching tire performance. Every component of the system has worked without any issues. The system is priced right. Tech support is excellent. I don't give many 5 star ratings, but for this system I'm happy to do so. My local Michelin dealer? Not so much...

After contact with the seller, I was able to finally buy a repeater from them which fixed my interference problem. Last trip, the monitor performed beautifully. Glad to see that they ONLY sell their system with repeaters included. I wired mine to be connected to the front clearance light on our trailer. We always tow with the lights on so there is no need to connect and disconnect or worry about battery drain while in storage.

This monitor used to work great, but now it is totally frozen. Our last trip of over 3 hours driving, the pressures and temperatures of all 4 trailer tires never changed a single degree or psi. The monitor is completely locked up. Even now, when our trailer is 20 miles away in storage, the monitor is still indicating the same values as it did a week ago. Wrote bellacorp an e mail, and they suggested that our backup camera is interfering with the TPMS. I see that now they are including the repeater with the purchase of their system. I don't know if I will give them another $50 for a repeater or just junk this one and buy from one of their competitors. Don't rely on this TPMS keeping you informed or safe. NOT RELIABLE

At first I had problems until Paul, the Bellacorp customer service rep, asked me a few questions .. including "did I have a weather station in my trailer?".. yes I do... turns out that the outside sensor for most clock or weather stations that show the outside temp use 433mhz frequency for their sensors which is close enough to the frequency that the TPMS sensor also uses so as to cause interference. BUT by using the repeater that BELLACORP sells for their TPMS, the system works great and starts updating tire temp and pressures after about 800' from the start of your trip (they 'sleep" while sitting still to save battery life; motion wakes them up and they start transmitting current data)
I highly recommend BELLACORP because of the customer service I received from Paul, AND recommend that, for best reliability, that you purchase the repeater with the system up front so you don't run into interference like I did at first. Its only about 35 feet from the rear tires of the trailer to the dash of my truck but there is enough metal to overcome in the direct line of sight that without the repeater, the system can be rendered unreliable if ANYTHING is transmitting in the 433mhz range. With the repeater, it boosts the signal enough to overcome all the metal and frequency interference resulting in a reliable tire status AND an alert IF any of the temp or pressure setting you choose to set in the system so you can get stopped BEFORE a failing tire causes hundreds of dollars of damage to your trailer. Even if you don't have any 433mhz interference from other sources, the repeater boosts the signal to get a strong signal past the metal barriers between your tires and the dash of your truck where you want the information, more reliably.
