Never had a problem in 5 years and have done plenty of travelling on rough roads and single lane tracks. Maybe if you’re going mudplugging or extreme off-road.Quote:

Yes, I agree that turning off when pressures are lowered seems really silly.Quote:

The TPMS unit also saved me once on my camper when one of the electric drum brakes failed and the sensor picked up on over-temperature (set at 60C if I remember correctly). Too late to save the brake (didn’t take long to strip the linings and ruin the bearings) but the tyre was fine. We were up near Lorella Springs at the time. I don’t think the factory units, or the internal TPMS systems do anything about temperature.

Another vote for the safety Dave system from me .👍
Owned for 7 x years . Trouble free, 1 x set new batteries on External screw on sensors fitted this year ( CR 2032 from memory? ). Useful for adding the van or trailer monitoring too. Does low/ high pressures and temperatures . Can order kit with extra sensors ( I have 11) .
Did lap of Oz 4 years ago with the bogie axle van and 26,000 km in Pajero ( before I bought the disco) not one puncture ! A bit lucky I guess but adjusted all pressures as ambient went up to mid 40 degrees in WA .
Rear Pressures went up about 10 psi from cold . Front only about 5 psi . Van only varied about 5 psi.
Had a sharp rock puncture rear tyre at lookout in Victorian High country last year and buzzer went bezerk Before we damaged the tyre so has earned it’s keep.
Suction mount to windscreen . Has a Loud buzzer warning if parameters exceeded so can stick it in centre console If you don’t want it on dash and still hear it ok . In built rechargeable battery or can be hardwired . Battery seems to last about a week if left turned on .

AStPW demonstrated how clueless he was in his attempts to use the TPMS, it seemed to exceed his mental capacity. [biggrin]Quote:

It also has a nice mute function - so the alarm can be muted and still display the current pressure. So at even lower pressures I can still see it. And if it changes again, the alarm sounds again.
Low speeds and pressures usually doesnt cause any issues in real world use - at those speeds you dont destroy a tyre if it goes flat quickly as you can feel and and react fast enough.
Never had a unit damaged in over a decade even bogged above the sills with the wheels covered in clay and dragging in the trench.Quote:

The ones inside the tyre - have seen several damaged at lowered pressure and hit a rock - which crushed the tyre into the unit damaging it.

I use the Safety Dave TPMS mainly because I want to monitor the caravan tyres as well. Like others posting here, I set the low pressures below what I would deflate tyres to and so far the only problems I've had are one disappeared in a shopping centre car park - probably a passerby curious at to what the sensor was? - and when I first got the system it is not easy to test because it takes 5 - 10 minutes of driving before the receiver starts reporting pressures/temperatures. You might get one up within a minute and others lag back until up to 10 minutes. Anyway, the problem was that the caravan sensors did not report back at all! when I got further up the track (Melbourne to Gold Coast) I called Safety Dave and they sent a transponder/relay unit to me free of charge to fit at the back of the car so that it could relay the caravan sensors to the receiver in the front of the car. That worked beautifully. Later, I mounted it permanently on the caravan towbar. The TPMS has never had to deliver on its real purpose, but it gives great peace of mind and is also useful to distract SWMBO by asking for all the readouts...
The small screen is mounted on a frame I have located on the dashboard along with a camera screen and phone bracket. It looks a bit agricultural, but it is a Land Rover!
Bit what about high speed at lower pressures, say running 28 in my defer on say the birdsville track, waiting for the tyre to deflate to 16 or 18 might start to cause damage by the time the alarm goes off.Quote:

I’ll check what the default setting are.....
Cross axle is the only annoying one, in the cooler weather last year on the border track I would get a cross axle alarm as the side/tyres facing the rising morning sun would have a slightly high temp and pressure than the other side. I assume I can change the setting so it’s not so sensitive. Although I normally try and face the front to the east when we pull up to camp.
Any sudden change still alarms for me.
And my minimum is set below 22psi.
If I air down below that I just silence the alarm. If the value changes again the alarm will go off.
The biggest problem on a D4 is that a tyre can go flat on the rear at speed and you won’t know it - the rebar that’s went through my LHR at lets say 110km/h flattened the tyre but it was undetectable at speed on the highway.
By the time I’d slowed down enough for it to become obvious the tyre was destroyed internally.
Even if I was running Birdsville track at 18psi at 110km/h (wouldn’t happen) the tyre will still hold out.
