When dealing with vehicle safety, one often over looked area is tyre pressure monitoring.I personally also am a great fan of a TPMS (Tyre Pressure Monitoring System). This will let you know about a tyre problem - slow leak, over heating, etc.
I have installed the TPMS from ppa car audio.

installation was simplethe item screwed on to each valve and the device was automatically programmed.
that involves a digital readout on the dashboard with a sensor on each tyres, i will now know what each tire pressure is on each wheeland i will know if i get a tire pressure dropand i will get a audible alarm if the wheel gets too hot
how good is thati will enjoy long trips more now with the added feature to my vehicals.
