Tire Pressure Monitoring

[Steve.k]

I just “installed” a tire pressure monitoring system and thought I’d share with everyone since it’s pretty cool and is easily removed for “correctness”.

I’m planning to do a 3day ‘rally’ organized by Classic Car Adventures and then I saw this TPMS on Massdrop and it was only $69.99 so I thought I’d give it a try.   

It comes with four valve caps and a little display that plugs in the lighter.   I ‘installed’ it in the time it takes to swap out the valve caps and plug in the receiver. It immediately recognized the sensors and displayed the pressure in the tires.   It can also display tire temperature. If pressures get too low or too high, it will set off an alarm.   

I drove around for a bit today and you can see the pressures rise as the tires warm up.  Very cool.  I’m hugely impressed with it.   For long trips, it’s nice to be able to keep an eye on the tire pressures. 

Just to be clear, I’m not associated with the manufacturer, supplier, or anything related.   Just a cool, useful device at a descent price.   

Here’s some photos

I have used that same system on my 4x4 VW camper and it worked when i was in a very remote part of Australia to warn me that I was losing pressure on a front tyre. Unfortunately the tyre had been punchered badly in several spots from the very sharp rocky road and not repairable.


Then about 50 miles further on had another waning alarm but this time it was one of the sensoers that had failed and wouldl not correct or reset its self thus making the whole system fail due to not being able to stop the warning alarm going off all the time.


Unfortunately when only one of the caps fail, you are not able to just buy one replacement and must buy a whole new system.

I could see that being vey useful for trailer or RV tires where sometime you don't feel a problem until it is too late.

There are a number of these for sale on Amazon, and at least one brand offers replacement sensors. The price point is pretty low and in many cases seem to be lower than a single high-quality in-the-tire OEM TPM module...

I was given four valve caps that show green when the tire pressure is OK and the green stripe goes away when the tire pressure sinks below 30 PSI. I don't know who sells them.
