I was embarking on a 1600 mile adventure to Palm Springs, and I wanted a TPMS for the motorhome and the car I was towing.
I looked at all the popular TPMS offerings, and I decided to give one of the cheap Chinese versions a try. Here is the one I bought:
There a couple that look identical on Amazon, different brand names.
Here is the report:
It worked amazingly well, and gave me great peace of mind on the road. The PSI alarms worked well, and they activated within a second or so. The temperature seemed like was a crap shoot - being out on the end of the stem, I’m not sure how accurate it is, or how it compares with the more expensive options. The tires always read 10 degree or so above ambient temps after driving a while.
The instructions were insane:
“PressSET for 3s to select the ‘tire number” intrernefce like as below, then press SET” I think they are translated very poorly from native Chinese.
If you liked the Rubik’s cube, you will love figuring out how to run this device. It took me a few hours to figure out. PM me if you want my home made instructions in English.
Only $150 for 6 sensors, dash unit, and extender/transmitter
Pairs up pretty easily
All tire values are on screen at all times - no cycling
PSI seems dead accurate to within a pound or two
Comes with a extender/transmitter, and has really great range
Good solar charger - dash unit never needs to be plugged in.
Both senders and dash unit sleep until movement is detected
AWESOME sticky mat - this thing will stay anywhere on the dash
Fairly bright and easy to read.
Alarms are plenty loud and can be set for high temp, high or low pressure, and rapid leak, however I’m not sure how that is determined.
No new tire readings until you are moving for a few minutes
Unclear if it knows when a sensor connection dies or is lost - it just continues to read the last value received
Terrible directions, very difficult to program initially
Alarms values are set per axle, not per tire - although display readout is for each tire.
Buttons are tiny and tough to push while driving
I have never owned one of the more expensive units, but I liked this unit just fine. Considering it was around a $300 savings, I would buy it again.
PS The PSI values in the picture are for the two front tires, the below outer readings are for the car being towed rear wheels, and the two inner numbers are for the tow dolly tires.
