YOKARO RVs TPMS, Solar Powered Tire Pressure Monitoring System with 6 External Sensor for RVs, Travel Trailer, 5th Wheel and Camper

I use these on my travel trailer’s four wheels. For the price you can’t beat it. I think there’s somewhat of a delay sometimes for the readings to update. For example, after driving at least an hour or two, sometimes only two or three of the sensors will show the pressure has increased about 4 psi, and yet the other one is still at its original psi. That’s obviously not possible. Then out of nowhere it will adjust and show the same as the others. The only other thing that sucks is the temperature cannot be changed to read Fahrenheit from Celsius. We don’t use Celsius here in America so I’m not sure why they wouldn’t make that adjustable.

Heading for a long road trip in an older vehicle, thought these would be nice to have. No problem on the trip but these helped reassure all was well with the tires. Simple to install, no problem with leaking after two months, accuracy corresponds to my mechanical tire pressure gauge.Don't be misled by the dimensions in the description - they're for the box that they're shipped in. Actual size for the display is slightly larger than a chess pawn. Valve stem cap sensors are slightly bigger than normal, but so what?Haven't had to do it yet, but includes a tool to change the battery in the sensors.Overall, great purchase especially for the price. Will be purchasing another set for a second vehicle.

Installed these today on my Grand Design Reflection 5th wheel. It took a while for them to connect to the display but once each one did you could tell the tire pressure and temperature from quite a distance. I was worried it would not work on the RV but even with it parked at the top of the driveway and the truck 30 yards down the driveway you can still see the current temp and pressure. Alarms seem to be flexible. Would rate it 5 stars but I have no history with it yet. Will update my review after a few weeks but for now I really like these.

The one thing I don't like about it is the max temp setting is 99 degrees unless I'm missing something, the manual is reallly crappy, like it was written by someone that didn't speak any English then ran a translator program on it, the sentences are almost incoherent. I don't know about you guys but my RV tires go over 99 really fast and then the alarms are just "beep beep beeping" constantly and I have no idea what the tire temps are, so it is mostly worthless to me at this point and I stopped using it becuase it annoys me. RV tires are designed to run much hotter than 99 so I screwed up should have done more research I was enticed by the 6 tire capacity and the price but I think it's probably designed for someone pulling a fifth wheel or travel trailer and not for a Class A rv. Would love to sell my used set, used for 1000 miles and perfect shape!

The peace of mind was priceless ! Being able to keep a check on pressure and temperature will hopefully prevent a blow out and more trailer damage. Seeing a tire heating suddenly, before it blows, is priceless ! I have been a good salesman for this product and generated a lot of interest with fellow campers on my "blog". So glad the price has come down to a more reasonable level !

Relatively cheap, simple set up and works well. Display is very, very dim even with pushing the backlight on. Not at all like the photo in the Amazon product description. It might look like that at night or maybe I got a dud display? I like that the 4 sensors are marked with which tires they go on - simpler than others that you need to program. All 4 of my readings are accurate (within 1 psi of actual) and all temperatures also within 1 degree Celsius. I've put them on my 4 truck tires (worked great) and also on my 16' trailer and my 27' travel trailer and still their sensor signals reach the cab of my truck. I don't know how quickly it will read a sudden pressure loss since I haven't had that happen since installation.

UPDATE!I did like these units until the stopped working after 2 trips. I suspected that I needed new batteries. Sadly the instruction call for a special plastic tool to disassemble the sensors to replace the batteries and none was shipped with the unit. I contacted the seller multiple times and was told “sorry we don’t have the tool and neither does our supplier. So without the tool the unit is junk!was skeptical since the trailer tires are more than 10 meters from the cab of our truck. They reported pressure and temps accurately! Easy install and use. Only issue is the small display is hard to see while driving so I have my wife check it periodically.

Great tire pressure monitoring system.I own a Civic 2008 and was looking for a system that could easily help me check my tire pressure.This type of device is easy to install (just replace the regular cap) and in a few minutes you can monitor the tire pressure of all tires.I was afraid of the weight/looks of the cap, but it is really small and if you don't look closely, it doesn't look like a tire pressure monitor.
