Hi there, last October I bought my first Porsche, something I've dreamed of since I was 13. I managed to get myself a black 1989 (when I was 13!) Carerra 3.2 Sport, which is absolutely wonderful - the best car in the world in my eyes

.
I have been looking at replacement tyres (mine has 4 x Goodyear Eagle F1 GSD3) on it: Rear (225/50 ZR16 92Y); Front (205/55 ZR16 91W).
I would be very interested to know if these the right tyre for the car. I am comfortable with the sizes and happy these are correct for my 16" Fuch wheels, but I have struggled to find out what the recommended manufacturer/model should be, including the speed and load ratings. It seems that the Goodyears have fairly decent reviews but also so do Michelin, Continental and Pirelli and other makes too. It seems that different people prefer different tyres, some obviously on different cars, but others on the same car - I have found a few reviews of tyres for 944's, but not many for 911s.
I understand that Porsche has given certain tyres on the market an N rating to signify that it is compatible with Porsche's recommended tyre type (different to the speed and load rating).
The handbook doesn't seem to show any recommended tyre (other than the size), and nor do various websites I can find. Many of the tyres around today are obviously more technologically advanced than my 21 year old car, so the handbook may not be the best place to look in any case. The only official reference I have seen is on Michelin's website, recommending a Michelin Pilot Exalto with 91Y at the front and 92Y on rear (otherwise same spec as above) - these are rated N0.
However they also say the following on their site so is it Exalto or Pilot Sport?!
"MICHELIN is Porsche's 'Worldwide Cooperation Partner'.
MICHELIN Pilot Sport is the leading tyre fitment for Porsche 911, Boxster, Cayman and new Panamera ranges."
Does anybody have any recommendations

I could just stay with the Goodyear Eagle F1's!
Thanks a lot
