Tyre pressure monitoring system - initial low / high settings

At 32 psi on the black top, I'd set for 24 psi minumum and 40psi max (or higher in summer). If running at 25-27 on gravel, I'd set for 21 low and 36 High.

I've never had a problem with a tyre going too high, always low ;-)

Cheers Mick

Howdy Tommy,

I have the same setup. I'm not wanting to start a tyre debate however for reference I run 40psi on blacktop, around 28psi on dirt and 16psi on sand. I sometimes vary the above depending on conditions. On the black top I have max set at 50psi . Minimum I have set around 34psi. I'm more interested in the dropping tyre pressures to avoid destroying the tyre before I know about it. We can't see our caravan behind us when on dirt roads so monitoring the tyres gives me some comfort.

You will be surprised at how the psi varies on tyres facing the sun in summer and also the psi drop when in very cold conditions. It's just a matter of keeping the min/max close enough to your normal psi settings without getting false alarms.

I use the temperature setting as a guide however I don't rely on it lot because I can't see how the sensors can monitor this very well at the valve stem. The temperature setting I use depending on season or if I'm using lower tyre pressures on dirt as this builds up heat. I usually have black top temperature set to 55 degrees because in summer my tyres can reach this just sitting with direct sun.

A few tips if I may:
a) Place some small pieces (a bit bigger than the sensor diameter) of High Density packing foam or similar, this will stop the sensors hitting your rims on corrugated roads
b) When replacing the batteries ensure you don't touch the battery +ve & -ve surfaces to ensure good contact.
c) Carry some replacement batteries with you, I purchased 20 replacement batteries off eBay very cheaply and have had no problems with them. Lithium batteries have a great shelf life.

Not sure about your vehicle...but here is the best reference I have found for your caravan http://www.peakhillcaravanpark.com.au/Tyre%20Pressuresa.htm

Look at the temperature/pressure variable hint....should work for the vehicle as well.

Hope it helps.

Hi Tommy
We did a Trip thru W.Qld via the Plenty Hwy to Alice in Oct 2012. It was my first run with the tyre dogs on the car & camper. They worked well and saved us from total destruction of one tyre, however the stones on the Plenty made mince meat of one sensor, it totally removed the screw on cap and clean broke the thin metal connectors to the battery. Then another tyre sensor started reporting 200+psi a few days later, so I knew this had failed internally also. So I strongly recommend some for of protection if travelling stoney roads! To the credit of the tyre dog crew, I sent the whole lot back to them and the they replaced both sensors (even the smashed one!) and fully tested the whole system all under warranty! That's great service. Enjoy. Stu
