EEZTire Tire Pressure Monitoring System - 10 Mixed Sensor (TPMS)

I see wildly different reviews on this product. Some give 1 start and others give 5. I have used the system since April 2018 on my GMC 350 and have zero issues. I thought I would comment on some of the reviews that I have seen. I believe I may know what is causing their issues.One guy shows a pic of a blown out tire and the system reading pressure in it. That is not likely. The system alarms in seconds if a sensor is removed (ie zero air pressure). It is easy as pie to test. Unscrew a sensor and you will get beeps immediately with a flashing tire showing what one it thinks is flat. Chance are his sensors were mixed up. One of them is probably reading zero. Just not the one he thought was on that tire. I suspect that at some point the sensors were mixed up and installed on different tires. The screw on type sensor have to be removed every time air is added. It is very easy to mix them up. They tell people to label them, but most probably don't or the labels fell off because they didn't cover them with clear fingernail polish like the manual suggests.I think a lot of issues are related to not knowing how to or not being efficient at programming the system. Programming is very easy if you follow the directions. There are a number of people that have great videos that walk step by step through it. I think the key is to program the sensors on your kitchen table first. Then take them out to the vehicle. It is easier than crawling around and trying to get to every tire and code it before the system times out. If the system times out the work is not saved and you have to start over again. I think that is the root of the problem for people complaining about having to keep programing the sensors over and over again.The next common issue I am seeing are people complaining about sensors dropping out while driving. RF interference will cause problems. If you have wireless cameras, refrigerators running, and other stuff that can generate RF interference around your vehicle it could cause problems. The way to solve that is by using a repeater. The repeater needs to be closer to the receiver than to the tires. Don't put a repeater in the very back of a 5th wheel and then expect it to transmit all the way to the tow vehicle. They recommend that the repeater should be installed in the front bay of the 5th wheel that is closest to the truck. Not in the back or middle. Metal can cause problems for it as well. The transmitter needs to be in a place that has the least amount of metal between it and the tires/receiver.I've seen people complain about the pressure readings. The EEZ RV guys have a video that talks about the valve stem and that the sensor needs to be able to push it in so air comes out that the sensor can read. In some cases those pushpins are in too deep and when screwing the sensor on it does not push them in at all or far enough to let sufficient air out to read. My bet is this is the problem for the ones complaint about that. This makes them think the batteries are not working and get frustrated when battery changes don't fix the problem. All it takes is a valve stem tool. Unscrew it slightly or replace it with another one. An easy test would be to screw the sensor you think is having problems on a bike or something else to test with. If it is getting a reading from another valve stem then chances are this is the issue.The only thing that I do not like is having to unscrew the low profile sensor every time I need to add air in the dual tires. They are very difficult to reach and unscrew. I can't put them in fast enough to minimize air loss either. The trick to get a good reading is to over fill the tire and reinstall the sensor. Let the system get a good reading, which will be high. Then slightly unscrew the sensor to let some air leak out. Screw it back on and get a good reading again. Going from high to low will let you get an perfect cold pressure setting. Most people fill to the exact cold pressure sitting and then when they screw the sensors on the tire pressure drops below the optimal reading. I am a bit tired of doing this though. I just ordered flow through sensors for my dual wheels. I believe it will be easier to put air in them. The front tires or ones with the valve stems facing out are easy.Speaking of tire pressure readings, gauges are different. Temperature makes a big difference in getting an actual reading. Most air gauges do not have temperature calibration. This is why the EEZ sensors may read different than a tire gauge. One guy mentioned that he had a calibrated racing sensor, but that doesn't mean it is temperature compensated. I have a Steelman 9797 (https://www.amazon.com/gp/product/B004IQ9I6O/ref=oh_aui_search_asin_title?ie=UTF8&psc=1) gage that is temp and pressure calibrated. It matches the EEZ readings exactly. The thing was $140. The only way to perfectly test the reading between the EEZ and a tire gauge is to use a properly calibrated gauge that takes into account ambient pressure and temperature.Another thing to note that I am not in love with his the anti-theft cover. Lots talk about this on here. I agree with them. I took them off. I could have left them on the front tires, but I don't think this is really that hot of an item to steal. If one ever gets snagged I may rethink this, but so far I haven't heard of anyone actually having their tire sensor stolen. They only work with the system they were purchased for. Every manufacturer has a different frequency and encryption.I have had zero issues with it on my GMC 350. I have driven it over 14,000 miles so far with the same batteries and sensors. The thing to keep in mind is that this system isn't just plug and play. It works perfectly if you take time and plan out the install. The main tip is to program it inside the house with every sensor on a table. Test it and get comfortable with how it works before installing the sensors on a vehicle. Problems are harder to troubleshoot after the system is installed.

Addendum: As I stated below, I was very happy with this product,BUT, If you have a trailer longer than 20 feet,( mine is thirty) you should probably buy the repeater. I was on a long trip with my fifth wheel, and I started loosing the connection to the back passenger side wheels. I Replaced the batteries and that solved the issue, but only for a short time. Then I had the repeater delivered to one of the stops on my trip, then following the placement instructions, I wired it to the marker light hot wire and presto, every thing worked as it was supposed to. Just buy the repeater. What good is the product if it quits while you are traveling. ? I don't know if the warrantee on Amazon is any better, but it is easier to purchase from the manufacturer's web site than on amazon. I still think this is a more than worth while product. Oh, one more thing. DO NOT buy the longer (through input) wheel sensors/transmitters. They are too long and too fragile. Buy the shorter ones. It is not a big deal to have to remove the wheel transmitters if you need to put air in one tire. Chances are that will never happen. If a wheel is loosing air you likely have a tire issue and will need more than just air replacement. . End of Addendum: First let me say that eeztire seems very concerned about you having a good experience with their product. They include extra batteries tools and rubber seals with the unit. Every thing you need is in the kit. I purchased the flow thru sensors and was surprised that they do not weigh enough to cause my tires to need re-balancing. My tow vehicle is a Toyota Tundra with stock tires and rims. It appears that if I get too close to a curb, I could damage these flow through sensors. So if that is a concern and your willing to give up convenience when filling a tire, you might want the shorter sensors.. Some easy tips for an easy install: Make sure you follow the directions. Read and understand them before you start. They are detailed and simple to use and have a couple of options. I did all the settings before I installed the units on the vehicles. I think that might be teh easiest way. Make sure the locking screws on the sensors are backed out far enough so they do not contact the valve stems threads, before you want to lock the sensor. I read one reviewer that had an issue cross threading when installing the sensor, I suspect the screw was in too far. If when you start, you have a valve stem that does not have a cap on it, I recommend screwing a cap on first to clean the dirt out of the threads rather than using the more expensive sensor to clean the threads. My tires are all set at forty pounds. When I creating my settings I used the default minimum tire pressure warning of 35 pounds. When everything was completed the EEZTire system showed one tire was about 36 pounds so I made a mental note to put air in the tires.. The next morning when I got in my truck, the temerature had dropped from the previous day, and the alarm went off saying I had a low tire and the unit indicated which tire it was and indicated that the pressure was below 35 pounds. None of the other tires showed the pressures on the screen yet, but I was not even out my short drive way yet. Barley moving. People have mentioned that it takes a while before the tire pressure shows up. This is true. How ever, even though the tire pressure was not showing on the screen yet, I had a warning of a low tire. I'm very satisfied with that. since I knew I did not have a leak, and I recognized teh issue, I continued to drive, and since driving causes tires to warm slightly and for the air to expand, that 36 pound tire took very little time to be above the warning limit. Then , after all the tires had warmed up , I took the time to inflate all the exact same pressure. One or two pounds difference on each tire will not make a difference. After a few days of not extreme temperature changes , I find that the tire pressure changes as much as five pounds. I am extraordinarily happy with this device. Two years ago I had an expensive flat tire on my fifth wheel. I am confident this will prevent another. Almost forgot, I originally used the suction cup mount to fasten the monitor to the windshield and had it low on the dash. When I moved it up to barely below the rear-view mirror, it received the signal from the back wheels better and faster. If the suction up mount continues to hold after several months, , I will likely hard wire to the dome light so the wire does not have to drape down to the 12v cigarette socket.

Generally set up & installation went well (instruction are OK). We use them on our Class-A motorhome and the towed vehicle. Quite often we seem to miss one or more readings on the RVs rear tires (dualies) and when towing our car we usually have to wait several cycles to get those readings & sometimes do not get readings on all 4 (I still need to install the booster though, so might be 'my bad').I found the 'lock nuts' to be a real pain in the towed car as I check/fill those tires regularly. I don't mind them on the motorhome though I also have tire pressure equalizers rigged on those and I don't have to adjust the pressure in those tires near as much due to the difference in vehicle usage.Not sure if the tire caps that have a 'fill thru' valve would have been a better choice for the car but I'll use what I have since I was a bit concerned with the extra size/weight of those.

I installed the sensors on my travel trailer and switched on the monitor. In my opinion, it takes far too long for the monitor to display the readings of all four sensors. I have to turn the monitor on about ten minutes before setting off to get a complete reading. At first I thought that the sensor batteries were weak, but they were not. However, the system works as designed once the communication is established.

Bought with 8 sensors Installed 4 on pickup and 4 on fifth wheel trailerTakes 10 to 15 minutes to sink sensors to module so don't turn module off if traveling dailyThe suction mount does not work find another way to mount itMet factory rep at Quartzite RV show 2019 and he knew that mount did not workHe gave me another mount from his booth

Used this to monitor truck and trailer tires. The system works very well, and since installed at this time last year has operated without problems for about three months of time on the road. Highly recommended for monitoring a travel trailer - one tire failure back there could wreck a wheel well on the trailer. Not to mention the cost of the tire and the possibility of an accident.

We were using this for our 5th wheel t.v.. The alarm setting was not accurate and did not go off at the set temperature. Also the tire display on the monitor only worked intermittently. A rep from the company called when we put in for the return request and said they could resolve the temp setting alarm but the tire display was probably caused by interference with the electronics on our truck. This was not indicated with the product info or any reviews. We had to pay to return it as well. I fully believe the monitoring system is a good idea but not this one for our needs/set up.

Just a quick review, the product was quick to install following the instruction provided in the box. No issues installing the sensor on to the trailer tires. Just a note that I had to get my wheel bearing re-pack so I replace the valve stems with metal stems. The pressure sensor was out by about 6 lbs on the first tire that I check. (Tire pressure measure 61 lbs but the sensor said 54). Knowing this, I used it as baseline as I was driving to give me feedback that I was having a leak more than over pressure.. The right-hand tires were 12 degrees hotter and was not sure why until I remember that the muffler was on that side. Over all very happy withe the product and would recommend it to both friends and family.
