YOKARO Wireless TPMS, Tire Pressure Monitoring System for Cars, Trailer, and 4 Wheeled Vehicles, 4 External Cap Sensors, Black

This product is awesome, we have a 31ft camper and towing it with the truck it works great, don't have any problem with connecting

Works as expected, but it's looking like the solar charging may have stopped working a few months into use. Charging via cable lasts a significant amount of time for use, but defeats the purpose of this device being solar charged. Support was responsive with emailed questions prior to sale but I have not approached them yet on the solar charging issue until I've had a chance to troubleshoot some more on my end.

I was a little bit hesitant because I was not sure it would work on my travel trailer but glad I bought it. It works great! A little slow to read all pressure but it doesn’t bother me. I did a lot of research and those RV specific TPMS cost around $300 do this is no brainer for me. My TT is 26ft from bumper to hitch and ram 2500 6’4” bed crew cab. I placed monitor on my dash and has no problem with range. Hope this helps other RVers considering TPMS on their TT.

Used on a 32ft 2018 Grand Design Imagine 2670MK. Pulled with a 2017 Silverado 2500 crew cab.This TPMS saved me on 6/28/18 on my maiden voyage with my new trailer. I had brand new Good Year Endurance tires installed, replacing the factory tires. One GY tire had a defective sidewall. The tire had a sidewall blow-out with only 200 miles on them. No damage was done to my trailer thanks to this TPMS.I do recommend buying the Repeater For TST Tire Pressure Monitor System - TST507REPEATER - https://smile.amazon.com/Repeater-Tire-Pressure-Monitor-System/dp/B00KPQZV9E.I tried this unit without the repeater and it was receiving an intermittent signal. I contacted Yokaro via email and they promptly responded. They recommended this same repeater to me since my trailer was so long. They said the TPMS tire sensors only have a range of about 26ft without a booster (my tire sensors to the dash of my truck is about 40ft). After installing the booster, it has been very responsive and accurate. I HIGHLY recommend.

UPDATE: I pulled the tires from my 32' travel trailer, installed new tires, new short metal valve stems, put the sensors on each tire, and had the tires balanced. The receiver picked up all four sensors without a problem. Now this is with the receiver near the tires. Because my trailer is large and after reading that for some the sensors worked fine on their trailer and others said they had trouble I decided to go ahead and look for a repeater. I was unable to find one sold by YOKARO so went looking for another brand repeater. Most say "will work with most TPMS". Well I didn't want to take a chance the repeater wouldn't work, so I sent an email to YOKARO through Amazon asking if they sold a repeater or if they could tell me of one that would work with their TPMS. I included the date of the order, and order number. The very next day I had my answer. Rey at YOKARO told me they did sell one but not on Amazon, but I could purchase one from them through PayPal. Next email to them was for the price and shipping. The following morning once again I had a response. I sent the funds through PayPal and a follow up email with the PayPal transfer PDF'd. Rey verified the shipping address and the following day I had my DHL tracking number. As of this morning DHL is showing the tracking information so my repeater should soon be on its way. I'm not sure why others are having problems contacting YOKARO. I had absolutely no problem at all. Rey was prompt, very friendly, and very helpful. I also must say that Rey's English is excellent as there was no confusion in communicating at all. Considering that most long range TPM systems designed specifically for travel trailer or trailer use run into the $300+ range, this is an excellent deal. From my testing, the travel trailer tires were displaying with in 1 to 2 psi of what my gauge on my compressor was showing and I know my gauge is fairly accurate. I believe this will do exactly as advertised and I can't say enough about Rey and the excellent customer support provided. Rey even included in our last email "If there are any problems, please feel free to reach out, I am always here." I hihgly recommend YOKARO, and just to clairify, I have not received any discounts or special offers. This update is soley because of the excellent customer service.----------------------------Installed on two of four travel trailer tires (the other two to be installed later this week). The unit reads the TPMS sending units fine. I programmed the receiver for the tires so the alerts would go off when they should. The sending units are easy to install. I put on solid valve stems (as short as I could find) and screwed the TPMS sender onto the stems. I then had the tires balanced. If I have any complaint it's that the receivers back light is dim during the day. On the positive, it's easy to program, charges without a problem from the built in solar panel, and it does the job as advertised. My only remaining question is will the sending units signal reach from my travel trailer tires to the receiver? I know this may be a problem and will have to test to see if I need to get an option signal booster.

This TPMS will probably do what needed. IF i have anything to say; it would be that you can change several options for it. Like switch between PSI and whatever other preasure measurement. But Degrees Celsius is only temperature. also. When disconnected from power. Your saved parameters are GONE. the only thing it keeps is you chose PSI. But your max and min and temp alarm settings_GONE. The initial "sleep feature is annoying too: right from start the sensors will not send a signal to the main unit UNTIL they are spinning . But then I did notice all info seemed to come up. I do question the temperature accuracy. After a 20, mile drive a quick stop then another 20 miles back most all freeway travel the TPMS said my tire temps were only about 24/25 celcious for fronts and backs were about 20/21 Celsius. Time will tell. i check it to start with on my car but baught it for monitoring my travel trailer tires. So i can't yet assess distance reading.Updated 6/8/2020I still have the TPMS unit. Been thru two sets of batteries in the sensors. Annoying that 3/4 of the time with the display in the truck I cant get all 4 tires of the trailer to respond.. that is until we are like maybe stopped to check in to campground or backing into our site.. THEN all 4 reading will finally be displayed.Another negative about this unit.besides once unplugged all saved parameters gone. Is that the I found out the voltage reading is quite a ways off. It says my truck is charging at 13.8V but I removed it and inserted my multimeter leads and I'm actually voltage is coming into cab at 14.10. Dont seem like much until that number drops down and its scaring you it's a totally reading low. Definetely would think twice before purchasing THIS product again
