Tyre pressures need adjusting as the seasonal temperature changes and should be checked once a month with a pressure gauge.
The tyre pressure sensors are there as a safety feature to indicate if a tyre is losing pressure during a journey or since it was last checked not indicating with a yellow warning that they need checking.
I guess I learned routine car maintenance when car's suspension and king pins needed regular greasing every 6000 miles so a quick check of tyre pressures, regular washer fluid top-ups, lubricating door hinges and stays etc. is second nature.
Rant over ?
