As you all ready know there are various systems out there on the market, I originally bought my first Tyrepal system in 2011 and then bought the newer version last December when a discounted offer dropped into my in-box.
The one that i use is the
TB99 model for van use as the pressure sensors now go up to 99psi it copes comfortably with my vans high tyre pressures, in all essence when I have the van on the back i put the rear wheel sensors from my truck rear wheels onto the van wheels and alter the pressure settings to suit. If you want to go all bells & whistles there is a system to suit, but what i am bothered about is when you get a slow puncture far too often the tyre will be destroyed before you realise what has happened worse still it takes the caravan wheel arch out with it.... so this system is designed to warn you of a drop in tyre pressure that way if you heed the warning and pull over you could just have the price of a puncture to be repaired rather than something more drastic happening...
Is it worth it..... well in my mind yes but everyone has there own opinions,as people have been towing for years with out anything happening ....
Puncture repair £15.00......V ...... a few hundred pounds or more to repair the wheel arch and other damage plus a new tyre,
some insurance companies are now offering a discount for using a TPM system.
A quick google found this......
