## Description

Tymate Tire Pressure Monitoring System-Solar Charge, 5 Alarm Modes, Auto Backlight & Sleep & Awake Mode, Tire Position Exchange, with 4 External Tmps Sensor (0-87 psi)

Review: This product helped me avoid getting stranded on my long drive as the real time display allowed me to notice a serious air leak in my rear left tire.. I immediately searched for the nearest Garage and got my tire fixed. -- A real life saver.. Very useful and practical product. -- Prashanth
Review: I bought these to confirm I have a VERY slow leak in one tyre. They install very simply in only a few minutes. The solar panel keeps the battery topped up well, I don't know how long the batteries on the tyres will last yet. The alarm is un-missable. When I got into the car after the tyre was leaking, the alarm started beeping quite loud to let me know one of the tyres was under inflated. Once I topped it up the alarm stopped. Also when when I unscrewed the cap to top it up the alarm sounds to let you know it's not installed. The display is clear and simple and tells you everything you need to know at a glance. I didn't know that tyre pressures increase when driving, as well as the tyre temperature increases (which should be obvious, now I think about it!). The system looks after itself and all you need is a quick glance to check everything is ok. I think its peace of mind that makes this such a useful product. Btw my car is a 2009 VW Polo, which is why it doesn't have this built in like a lot of never cars. I would highly recommend this to anyone to save time and give you peace of mind before driving.

## Questions & Answers

**Q: Will they work on a 30 foot travel trailer?**
A: Yes, but I would not buy another Tymate.  We have the four and six monitoring systems.  The four one has a senior that has not worked properly since we bought it.  The company will not respond to my request for help.  Now all of the sensors don’t work.  We had it only 5 months when it quit working.  They advertise a 24/7 help line.  Good luck with that. No phone number to call.  I give these a 0 rating.

**Q: How get in touch with the seller?**
A: It’s not easy to get in touch with them, they don’t respond to emails.

**Q: How about the warranty service？**
A: The warranty period of our products is at least two years. If you encounter any questions about the product during use, please contact us in time  +1(855)-492-9277][EST 9am-5pm Monday through Friday].Support[tymate@afterservice.vip] or contact us directly through Amazon.

**Q: How do I contact the seller when I have a problem during use?**
A: The included instructions provide a phone number. I used it when first setting up and found the support very helpful.

### ⭐⭐⭐⭐⭐ Review
*by S***T on 26 April 2021*

Overall, this is a pretty decent item. I've only had it for 6 months now, but I really like it. It's especially nice because it's pretty accurate and costs ~$50-60 (wait for a deal) and I don't have to waste money going to get new sensors replaced for $100+ a TPMS sensor. Overall, it was worth the purchase as it's very convenient to see the current pressure/temperature for each wheel (if you don't have that with your vehicle already). This product works by replacing your cap for the air valve with a sensor and nut. Once the cap is off, you thread on the [locking] nut and then put on the sensor hand tight. You then "loosen" the nut which winds up using friction to keep the sensor tight in place so someone (without the included 1/2" offset wrench) cannot remove the sensor(s). It takes an extra 10-20 seconds to add air into each tire because of this mechanism, but it's not a big deal. The unit itself comes with adhesive to secure to whatever surface you want which is very helpful so it doesn't move around easily. It constantly charges via the sun. Something to note: I believe the unit turns on when it senses vibration (via closing a door or starting the engine)--but can be turned on (e.g., the display) by clicking any of the buttons. It will then show whatever data was last recorded from your previous trip, BUT once the car moves it takes about 5 seconds of the wheels rolling to update the data (automatically) to the currents stats. Just be aware of that. It doesn't bother me, personally. The description says it has an accuracy of +/- 3 psi. That's an absolute range of 6 psi--a lot of room for error for my liking. Despite that error being apparently similar to other items on Amazon, I have found with my trusted digital tire gauge that this unit reads +/- 1 psi most of the time. That's really good. There's a lot of settings on the device that you can customize to your liking. Other reviews have stated that once it starts beeping (i.e., the tire pressure drops below a set threshold), the beeping will not stop until the pressure is increased. That is FALSE. All you have to do is hit one of the buttons on the top and it stops the beeping. ***Due to the small space you have to tighten/loosen the "security/locking nut", you need the included 1/2" offset wrench (feels like just sheet metal or the type of wrench that comes with furniture). I have an assortment of tools and cannot find a tool that would suffice. Maybe a small open-end 1/2" wrench that is bent or an open-end crowfoot could do it. But a flare nut crowfoot or standard open-end wrench will not do it. I cannot find the included wrench anywhere; so if you lose it, it might not be fun. I WISH THEY WOULD INCLUDE 2 OF THESE WRENCHES IN THE PACKAGE.
