Like you, I had an early set of the Jette 400s and have got rid of them now. One broke off altogether on a dirt road north of
Iron Knob (not a really rough track) and another one broke off at the stem. They were replaced free by Derek from ABR, but the other thing I found with them is that they were a damned nuisance on a vehicle where you often adjust tyre pressures. Probably okay for a highway vehicle with fairly constant tyre pressures.
Being an old bloke, I found it would take over 15 minutes after dropping/raising pressures, to muck around with the controller thing inside the cab and get it re-set to the newly set pressures. Too much beeping as you drive along too, as one or more sensors would lose it's signal from time to time.
I still like the idea of the monitors and will buy another set IF/WHEN:
The cab-mounted monitor automatically sets itself to the pressure that actually exists in the tyres. So, in my mind, the perfect system would involve:
1). You get in your vehicle after having screwed the sensors onto the valve stems (I would use the extra set of valve stems fitted to the rims in such a way that the sensors were totally protected from stones etc).
2). You press and hold-down a button (or 2 buttons if need be), and wait for several seconds.....the cab-mounted monitor would be using this period of time to "search" for the signal from each monitor and in turn would register the existing tyre pressure as the "base-line" that it needs to work from.
3). You arrive at a sandy spot (or wahtever) and decide you need to adjust your pressures.
4). You get out of your vehicle and use your chosen tool (
mine is called a Ferrett tyre deflator...GREAT) to reduce the pressures;
check with gauge if you need to.
5). Repeat step 1
I suggested this type of system to Derek at ABR and his advice was that it would be too complicated to produce such a system.... I reckon it's only a matter of time.
