In flight Tyre pressure monitor

[JerzyGeorge]

Hi All,

 

Can you recommend reliable tyre pressure monitor which works in flight?

 

I looked at some TPM available on the market but I think they work ONLY when tyre is rotating which obviously is no good in flight, when I want to know before landing that I have a soft or flat tyre.

Dont use a 'tyre dog'.

 

Had one setup on a small truck, all seemed good, till i unhooked the trailer, and 50 miles down the road, the dog was telln me all was still good, with the trailer 50 miles away. :(

Plenty of them do that, takes a couple of wake up cycles before it realises its gone BUT when a tyre looses pressure is picks up straight away

 

I assume it wouldnt tell you a sensor has fallen off.

I use FOBO tire on our car and they seem pretty good although the first thing you should do when you get them is remove the batteries and replace with some decent ones. Original batteries lasted one month and the replacements have been going for over a year!

 

It will display on your phone and even when car is stopped it will give a reading. It comes with an in cab unit which as far as I can tell checks when the wheels start to move but as I said the phone display works full time.

 

Maybe a little overkill for a plane though? But if something is worth doing it is worth doing well.

I think that is correct, mine give an alarm when pressure is lower than the set limits but if you unscrew them completely the alarm will not activate, but I guess if your wheel had no pressure at all it would be fairly obvious.

I reckon mine have already paid for themselves by picking up slow leaks early which would have led to tyre failure if not found in time.

The reason i got it was coz i cant see through dust of its go,n flat, and usualy cant feel it either. So if it dont register a sudden loss, like a blow out, or a slow leak, wots the good of it?

 

$700 a tyre you have to stop well before its flat, coz these modern crap tyres will shred in 20'.

 

Not sure how much range it was sposed to have ( how many trailers you could hitch up), but im pretty sure it aint 50 miles.

 

Thats alota trailers.

No it does read sudden blow out etc, I cant even unscrew mine as fast as possible without alarm going off.

 

I know for a fact they alarm on blowout but best of all most alarm on high temp too - which is actually what causes many.

 

I think its only when its on a good tyre and and looses coverage that theres a issue.

Trying to add slime (preseal) to a tyre fitted with a pressure/temp monitor is a dumb idea.

 

Don't ask me how I know.
