Iam wanting to fit these TPMS to my van as being able to pickup a low pressure on a wheel might be the difference of getting a tyrč repaired than replaced. There are 2 types one is external screws onto valve stem and other goes inside tyre. Any comments advice please.
We fitted TPM's from Safety Dave to the tug & van 6 years ago that monitor pressure and temperature.
On one occasion it detected a low pressure on a wheel on the tug, front left when in O/B Qld. Stopped and found screw in the tyre. Put some air in and continued on to next town for repair.
Its a massive benefit knowing you know what your tyres are doing all the time especially when in remote areas.
The sensors that fit externally to the valves sense pressure and temperature but really the valve stem temperature not the tyre temperature. The internal sensors sense pressure and tyre temperature. I think temperature is a "nice to have" information, not essential.
There are some claims tha external sensors can damage the valve stems because of the extra weight of the sensor on the end of the stems, particularly in rough road conditions. There are techniques for stiffening the stems against damage by using some stiff tube around the length of the stems.
I have external sensors without any reinforcement tubing on the stems. No hassles with the sensors for three years so far.
I have the Safety Dave set. Started on a caravan then transferred to the motorhome. In the 10+ years I have been using them I have replaced 2 sensors and added several to cater for the additional wheels of the MH. Had to replace the display unit when I dropped it. The units have saved me twice with slowly deflating tyres. Paid for itself.

I do, not sure if you should or not, would think they've gone to sleep. Just be aware, if you have a tandem c/van, depending on how far back your wheels are, you may need a booster, we did, the back wheels stopped displaying when on the open road. The TPMS came with a booster in the kit. Cheers Basher
I don't believe 'They only start working when you get to roughly 20kph'. I turn the monitor on when we start shutting down the camp. By the time we are ready to roll between 10-30 minutes all sensors are reporting. MH hasn't moved other than wobbling from us moving around (maybe that initiates them). I also change all the batteries if we are heading out on a long trip though they seem to last for 6-12 months at our usage rate.

Mine are from ARB, for the car only, but I wouldn't be surprised if they all came out of the same factory. About 30 metres from our garage they all show tyre reading. So more of less instantaneous.
