Any recommendations for a reliable TPMS for a caravan ?

Have a look on ebay, there are a lot of new very compact TPMS's available for around $30. I've not long bought one to fiddle with and have been quite impressed.

They also come in six wheel for about $70 probably eight wheel but haven't needed to look for them.

I wanted a lower profile unit that would not take up as much space on the dashboard as the Safety Dave unit which I've had for a while.

It seems to do all that the S/D unit does.

Don't get me wrong, I've used quite a bit of Safety Dave stuff but there is a big price difference here. smile .

The iMars T240 on your attachment is the same as the one I bought and for the price they're very good - time will tell I guess.

IMHO there just another bit of junk to crowd your dash/windscreen and take your attention off the road ahead.

With mobile phones, dash cams, TPMS, Uhf radio, GPS etc, too many obstructions, I will ony grant one exemption and that is a Rear View Camera and that is positioned so SHMBO can monitor it and advise me of pending arrivals.

Phone is in the glovebox, UHF is gone dont need to listen to the BS and foul language eminating from it music is more calming, GPS is not required there is enough big green signs to tell where I am or to go, if a GPS is need to guide me to an exact location then SHMBO uses the GPS in her phone.

In 2018 TPMS warned of reducing pressure. We plugged the tyres. TPMS are a lot of peace of mind when remote. Saved us 3 tyres.

On that trip we initially got a flat tyre, I was checking tyres daily. Got a flat & destroyed the tyre. It was in a very inconvenient location, we only had one more spare. Also on a blind corner & I couldn't really move to a much safer location.

One very expensive new outback tyre which could have been avoided if we had TPMS. At least it saved us 3 more tyres on that trip after buying after market TPMS.

Many countries TPMS is mandatory. The software is in all cars, it just needs to be turned on & sensors put inside the rims.

The iMars T240 shows it monitoring four wheels. Are you using it to monitor your vehicle or van or two devices to monitor your vehicle and van? Does it have enough signal strength to monitor the van's wheels continuously?

I bought it to monitor the 'van tyres.

It's a 20' (dual axle) van and I have no problems with signal at the distance the wheels are away.

I already have a Safety Dave unit but it sits a bit high on top of the dash whereas these cheaper ones sit flat on the dash at about 25 mm high including a built in solar panel on top to keep the in build battery charged.

A bit of a negative attitude to technology that is designed to make your driving easier.

It is there to help, you don't have to monitor these things every 5 minuets, it will alert you if there is a problem.

Better than realising you have just had a blow out as your arse overtakes your elbow, and you end up with the tyres pointing skywards.

My is in the corner of the console, so is view but out the way.

The low & high pressure alarm is at 8psi either way, so one really can simply ignore it.

Best thing in the morning I don't have to get on my hands & knees checking tyres. Simply drive off, reach 20kph & you know your current PSI.

It's a no brainer!

In relation to dashcam comment. Someone drove into me this year pulling out of a parking spot. I couldn't prove it was them & they lied. I had to pay my excess etc. I now have dashcams. A neighbour is now putting in a dashcam for similar reasons.

Absolutely correct!

That's why I wanted to try this smaller version because it tucks away out of the normal vision beneath my camera screen.

With a bit of Velcro on its bum it sits nicely on the dash mat.

Hi Barney,

I guess you ordered the two units, one for the vehicle and one to monitor the van. Do you have any information about whether the signals ftom the respective sensors interfere with the ones of the nearby system?

For example, if you have one system for the vehicle, say, for the front right wheel, is there any interference or reading of the signal from the front right wheel of the caravan to the unit dedicated for the vehicle? Just asking obviously the units are the same make and type, and perhaps use the same signal frequency for the respective wheel of the vehicle and the van.

I bought a TPMS with eight screw on sensors and a relay for the caravan tyres. The trouble was that the one I bought, the maximum and minimum tyre pressures for each wheel could not be set. There was only one setting for all the tyres. That's worth watching out for but I've set it up so that the minimum tyre pressure is at the lowest tyre pressure. At least that will catch any tyre going down.

Magnarc · Guru

Just as long as its only temporary Mike!!!!!!!!

PeterInSa · Guru

Also B4 purchase check the price for replacements sensors( external on the valve), mine retail at $64.95, but alternative sources are availabel.

Replying to Watsea

G'day mate, they have not arrived yet but based on the research I did they should not interfere with each other. You would not want to be driving around in traffic and getting warnings from other vehicles.

I have 2 units to monitor vehicle and van.

No interference between any sensors.

I have been using the Safety Dave TPMS for the past four years and although I've had no tyre troubles, it is peace of mind that I appreciate. It also helps to distract SWSBO when I ask her to check the tyre pressures (even though I can see the display on her side of the dash). It did give some grief initially by not monitoring the sensors on the caravan. A call to Safety Dave and they sent a transponder to me which cured the problem.

I have what I think is a Safety Dave unit with 6 senders that my son picked up at a garage sale.
It seems to work very well, and it is reasonably easy to re-set when we air down for off road and sand conditions, but I find the ergonomics extremely poor.
1. It is very much larger than it needs to be.
2. The "vehicle" layout of the screen is "travelling" right to left. It should be bottom to top, so the sensors are the same orientation on the screen as they are physically as you drive.
3. It scrolls through each wheel, one after another, so instead of a single glance to check the pressures, it takes 20 seconds, or so, to see them all.
Poor design. Makes no sense.
Cheers,
Peter

My TPMS plugs into a 12v socket. I ran a socket to the console & hard wired it in. This an ARB model which only does 4 wheels. My gut feel is a second set would probably clash with the first. But this would need to be confirmed with ARB.

I thought about cutting it in but there was nowhere that this could be placed.

I have a saftey dave it now sits in centre consul, good for a slow leak but, we lost a wheel and saftey dave didn't blink an eye just kept on reading as normal except missed wheel that wasnot there. John had a major blow out in the gulf and again dave ignored it. Maybe 2 faulty ones.

My SafetyDave TPMS certainly barked at me when I had a blowout.

Maybe one, but never heard of one that Barks when you do a Lucille

Safety Dave warned me when tyre valve broke immediately saved the tyre

But it was because of Safety Dave large screw on sensors that caused the valve to fail in the first place as they do not fit in the recess of the rim and the valve are distorted

Not using the dust caps as i lost most of them on a recent trip
