550S-6 Tire Pressure Monitoring System
Come with A Repeater and 6 External Sensor
- Are you worried about a tire leak during a long trip, but you didn't notice it?
- You may be worried about a sudden surge in tire pressure due to summer heat?
- Do you feel anxious because it is inconvenient to check the tires on the highway?
- You may feel uneasy because you forgot to check the tires condition before departure?
To improve driving safety, you need our 550S-6 tire pressure monitoring system to help you monitor tire pressure and temperature in real-time and display them on the screen.
SOLAR POWERED & USB CHARGING
2 power supply methods (solar energy storage and USB Type-C charging) enable the monitor to operate continuously in any weather conditions.
4-WHEEL OR 6-WHEEL MONITORING
Considering the actual needs of users in daily life, the RV TPMS can be switched to 4-wheel monitoring mode and 6-wheel monitoring mode.
REPEATER ENHANCEMENT SIGNAL
The wireless tire pressure monitoring system can increase the wireless transmission distance from 40 feet to 98 feet after installing a repeater.
MORE CONVENIENT AND FAST
Our tpms adopts Infineon SP40 chip, which accurately, effectively and conveniently helps you monitor tire condition.
INSTALLATION DIAGRAM OF WIRELESS TPMS
The 550S-6 wireless tire pressure monitoring system is easy to install without the need for extra tools and manpower, and does not require complex wiring. Even beginners can set it up properly in a few minutes. When installing the repeater, simply connect the correct positive and negative wires.
SUITABLE FOR ALL 4-6 WHEELED VEHICLES
Considering the actual needs of users in daily life, such as pickup trucks and travel trailers, 550S-6 TPMS is designed as a system suitable for both 4 or 6 wheels. With simple monitor settings, you can switch from 4-wheel monitoring mode to 6-wheel monitoring mode, and vice versa.

I just finished one trip with my Class A motorhome and the product seems to do decent. I have a slight concern on accuracy since with a pressure gauge I've used before and have checked against others all my tires were at 90 PSI. However the TPMS shows them from 83-86 PSI. The TPMS does pick up my rear tires w/o having to use the repeater.During the trip the highest pressure I saw was 102 PSI and 102 F was also the highest temp I saw. While I wish it was more accurate (plan on checking that with other gauges later) as long as they register consistent I'm OK and it's great knowing the temp also.

Purchased for my RV and to be safe i even added metal value steps so it i would not get value stem leaks. The first device arrived with missing sensors and lock nuts. Could not respond to vendor because their email would bounce and support phone number was a China number. Contacted Amazon and they sent another unit. Now my issue is i tried to find a electronic copy of install instructions because print is too small to read. i know that sounds silly but the font is quite tiny. Once again i am stuck but plan to drive 50 miles into town to get it enlarge. If you buy a B-QTECH product know there is NO support what so ever. I have tried and Amazon has tried and it is not possible.

This is a fairly innovative design that in practice has a few weaknesses. First the good - no running wires! The sensors communicate wirelessly to the monitor, and the monitor itself is solar-powered, so you don't have to run power to it. You do have to run the antenna to a spot where it can receive signals form the sensors, probably at the back of your vehicle. It does a good job of updating constantly and alerting you to low pressure or high-temperatures. The instructions are quite clear, albeit fairly involved, and do a good job of covering installation and usage. Amusingly, they spell 'Tire' as 'Tyre', so NOT a US company!On the down side, I can see the solar power being a problem if you drive a dark vehicle. Normally the monitor would be installed facing slightly up so it can be easily read. Unfortunately, the solar panel is on the back side of the monitor, so it must be installed on the dash where it can get sunlight. If you have a lighter colored vehicle, the indirect sunlight bouncing off of your hood will probably suffice, but a darker vehicle may provide insufficient indirect light, so you will need to install the monitor facing straight back so the solar panel can see the direct sun,

This is perfect for my overland setup. Not only can I monitor the tire pressure of all four on my rig, I can now also keep an eye on my trailer tires. I have on board TPMS but all it tells you is if you're in trouble, never defines the actual pressure. These can tell me how many pounds I'm at to let me know if a problem is developing, and again the cool part is now I can keep an eye on my trailer tires which were always just a mystery.Cannot wait to install!
