Tyre Pressure Monitors

Sensa Trye unit with the internal clamp type sensors. Haven't broken it yet and it's done a lot of very rough work. I have just bought the 6 to 14 sensor model for the new beast with 8 sensors. There is a 6 sensor car kit (4 + 2 spares) ($630 or thereabouts) and a 6 sensor towing kit which has additional sensors for a trailer, caravan etc ($830). I am using 8 sensors.

Cheers Mick

I have used the Tyre Dog for the last couple of years and they have done some pretty rough off road tracks. I have not had any issues at all. I swap the sensors from my on road to off road tyres and it is as simple as screwing off one valve stem and placing on the other. I dont use the cigarette plug power lead, just internal batteries and they have lasted 2 years so far.
The other advantage is that if you happen to get a puncture, you can quickly change the sensor to the spare.

Hi Alastair, We tow a dual axle van & have a Jette 400C monitoring system & run eight sensors all told. We do not venture off the black top & are more than happy with the set up. We purchased it from Derek of ABR sidewinder & were happy with the price & his excellent service.

The system works well for us, is easy to set up & maintain & most importantly gives us peace of mind when travelling.

My understanding off TPM's is that people who do off road work in sometimes harsh conditions require something more sophisticated so a system that suits me might not suit you. Have a look at thread # 69889 for some other comments as well. Cheers

No matter what brand of tyre sensor you choose to purchase, it will go a long way towards giving you peace of mind in regards to the tyres you have running on the road, especially if you tow a caravan, on or off road.

The Sensa Tyre unit is quite good but can be a real mongrel to set up and if you actually decrease tyre pressures for sand driving, all your pre set data is out of wack ~ so a reset is needed, or you need very broard parameters in your settings for very low to high pressures.

I used the Sensa Tyre units for several years and during there use~life span~ the unit suffered two dead internal sensors, these sensors have a sealed internal battery, so the wheel sensor needs to be discarded, this means a full tyre strip off the rim.

I also had the requirement to fit an inner tube to one particular tyre that had a carcase fracture(s) between the tread blocks, this made the internal sensor usless as it could not be used with an inner tubed tyre. The tyre was used with the inner tube for a further 4 months, until fitting the BFG's.

I now use the Tyredog Sensor units ~ these are valve stem sensors and do not require dismounting tyres to fit. The display screen is small enough to be mounted on the face of the interior rear view mirror and can be used with it's internal battery supply or it can be hard wired via a 12volt power outlet.

I run a six sensor set up, which means I can not add extra sensors as the display read out is fixed on sensor numbers : eg 4 - 6 - 8 - 10 etc which increases the display screen size to a degree.

The Tyredog unit has already saved one Desert Dueler AT 693 by showing a small decrease in pressure ~ before possibly destroying the tyre. I run Desert Duelers AT's on ~ highway and BF Goodrich mud terrains ~ off road, but use only one set of sensors and display screen, this can not be done if using the Sensa Tyre system.

I also run a seperate 4 sensor unit for my caravan.

I have no affiliation to Tyredog or any of it's suppliers ~ the Tyredog system is simple to set up and accurate, just a good device really.

We run the Schraeder system which is now a Toyota approved accessory and ours can handle up to six tyres. So works really well if you don't tow.

But we have started testing a Hannibal system that can cope with up to 14 senders as we are hooking up an Ultimate Xtrak shortly and want to be able to manage six tyres on the Prado and four on the camper trailer. Testing to date is excellent and we have fitted an exta antenna at the back of the car to ensure we get the best possible signal from the camper trailer

Both systems use internal sensors as we have found the external ones a touch vulnerable in rocky country

Thanks everyone for the replies.

I am inclined towards the internal sensors as most problems seem to be with the valve stem screw on units. Also concerned that the external units will be a pain when changing tyre pressures regularly.

Now HERE'S an interesting concept. NO BATTERIES !!

They reference "SAW" technology (Surface Acoustic Wave) which is also used in the transponders for toll registering. There would be some electronics in the transmitter but relatively simple. Electrical power is provided by the interrogating transmitter so no batteries.

Graham, this would solve your replacement battery concerns but the warning pressures, being pre-set within the transponders would not be able to be readily adjusted. So they would not solve my requirement. Damn!
