Tyre pressure warning system

[the911 sc]

i had the sensors on the 997 and they were a pain - the batteries gave out and I had to replace them all at 120 quid each!!.
What did help was using a nitrogen air fill. Porsche do this anyway but I guess a few other places would too.
Glad its not sensors on the RS - My Q7 has the system too and only once came on (where it was right that I was slightly low on pressure)

They saved my bacon in my C6 as I was able to see how quickly the air was exiting and therefore able to stop more safely.
