That's very interesting. I have never experienced any noises or rattles in nearly 2 years of driving my 997S. And if this is because of the tyre pressure settings I have been using, then that's something I would never have realised or thought of.

I have always used partial load tyre pressure settings even when I drive at speed on the motorway. In fact, I use slightly more than partial load but less than full load.

Partial load is 2.3 bar front, 2.7 bar rear. Full load is 2.5 bar front, 3.0 bar rear.

I always use 2.4 bar front and 2.8 bar rear. I seldom carry a lot of stuff in my car. At most, there's me, my wife and a few bags (or some grocery shopping) so partial load works fine for us.

@Alex: I agree - IMHO it's best to wait for about 2 years for all the wrinkles to get ironed out. That's what I did. I got a MY07 car in Nov 2006 which was 2 years after launch

@spluff: I'm so sorry to hear of your problems. Hope they get resolved soon.
