Tire Pressure Monitoring System for My Dominar
« on: June 15, 2018, 09:22:05 PM »
This is a first impression review of a TPMS for motorcycle installed on my Dominar.

Background: With the ever increasing puncture possibility of my tires due to traveling on heavy traffic roads like the ORR, I was on the lookout for a reliable TPMS for my motorcycle.
I had two options, one with external sensor and another with internal. Steel Mate had one with an internal sensor which was my preferred choice but, being very expensive ( 90-100$), it was dropped.
The next choice was with an external sensor. The TPMS here is a generic brand on Aliexpress. External sensors are easy to install and require no balancing but are cumbersome to remove when filling air and prone to theft. An anti theft nut is provided however. I managed to procure one at a good price of ₹2500.




Installation: Installing the sensors is quite easy. It just invokes removing the old Valve caps, screwing on the anti theft nuts and screwing on the external sensors. Each tire has its respective sensor. The sensors are calibrated with the display from the factory itself. A spanner is provided to tighten the anti theft nuts. The handle bar mount is attached to the handle bar using a simple screw tightened manually by hand. The display screws into the mount and an adjustment screw with a damper is provided.


Display:
The display is a dot matrix display with multi colour option. It is powered by a Li-ion battery which is claimed to be blast proof. The battery has lasted me about 3 days with zero loss in battery  life as of yet. It features a micro USB port for recharging which should take about 2 hours. It Is waterproof with IP67 rating.
When tire pressure is low or high, it blinks with a red colour background and an audible noise is heard. Low pressure and high pressure can be set. Temperature is also displayed for each wheel and when the temperature crosses a set value, it alerts in the same manner. The display has two buttons, set and change. Set allows you to vary the settings as per the manual and the change button changes the values. The latter can also be used to switch on or off the display. The screen has auto off function when no motion is detected. The brightest setting of the screen can be set using the change button. 3 levels of brightness are available.

Sensors: The sensors are extremely light weight and are powered by a button cell. The cells are replaceable using a special tool to remove them from the sensor. Installation of the sensors is easy. There can be a slight loss of pressure when installing the sensors as they press the valve when screwed in. Pairing is done at the factory itself so upon switching on the display for the first time, the tires have to be moved so that the sensors become active and the readings are displayed.

Observations: Battery life is holding on well with zero los in battery life even after three days without switching off. Holds up to water or light rain for now. Waiting to test in heavy rain. Sensors have not fallen off. They are holding onto the stem tightly. Display is fairly visible in direct sunlight on medium brightness. Pressure of the tires are changing in a similar manner. The increments are in Syria of 2 PSI. Will take it on a long ride to check more changes.

Pros:
1. Very lightweight and compact design.
2. Easy readability of the display.
3. Accurate readings.
4. Easy to install and uninstall.
5. No balancing of wheel required.
6. Long lasting battery of display and waterproofing.
7. Replaceable battery in sensor.
8. Sturdy mount. No unwanted loosening of the mount or display.
9. Anti-theft sensor.

Cons:
1. Not anti-theft display.
2. If installed incorrectly, the valve can leak air through sensor.
3. Sensor looks odd in grey colour, would have preferred black
    sensors to match alloys.
4. Air filling is cumbersome. Have to carry the spanner with you
    always in case of puncture in order to remove sensor.

P.S: Will update as I have more observations. For now these are my initial observations only in city usage.

Good man. Can you put a pic which shows the sensor assembly to the tyre valve?

Yes I will update that picture.

Meanwhile, since installing, I have never charged the battery of the display even once. It is still showing full and going strong. The hot sun doesn't seem to be affecting the display in its functioning. Still waiting for proper rain to test the water resistance.

Hi Nikhil.. Please update how its holding up after a week of use. And what is the pressure change you notice after having one hour ride. Does the tyre pressure change drastically when the tires warm up?

There seems to be a difference in pressure values as compared to what is displayed in the air pump in the petrol station. A exact difference of 3psi is shown for both the tires.

Not much increase in pressure on daily usage. An increase of 1-2 psi can be seen with both the tires, the rear one being faster to heat up and increase its pressure. Still no leakage and battery still going strong.

Meanwhile, here's a picture of the sensor installed in the tire.

So this is the temperature and pressure reading after a regular afternoon ride back from office to home. Temperature at times goes up to 38?C. Earlier post gives you a picture of the same when in cold condition.
Also you can notice the battery status. This is without charging since I have got it and the display in on condition. Note that the display switches of if no movement is detected, so most of the time at night and during office hours the display is off but the unit is still switched on.

Hi Nikhil.. Can you share the link from where you bought this.
It seems to be a good buy as it display both temperature and pressure on wheels.

Bro is it waterproof that is wat I'm worried abt if sensor goes then it's of no use. I m not sure how it will perform if the tyre is submerged in water during rains. Do let us know. Coz the sensor has opening for battery.

Sensors are waterproof. I have tested in the rains. Not sure about water wading though. The display and sensors are IP68 rated.

I bought it through my dealer so no online link. However you can buy it on Aliexpress as well.
