James,
Me too, I had the pilot from Michelin, it was 7 days ago.
I changed it for Yoko A 539 in 195/50 15".
They are cheap, less than £ 180 for a set of 4.
They are absolutely fabulous compare with Pilots.
Better steering, better grip on the dry but also on the wet(the reason why I change the pilot).
If you want ultimate performance on track days, go for 185/60 13 with Yoko 032 R in soft. But if you drive a lot, It is not a good advise for your wallet. This kind of tyre will last 3000 miles and the price is double than A 539.
From my side, as it is a Christmas present : I will keep the A 539 for road and travels. 15" gives you good speed on road and motorways. May be for my next or following birthdays, new minators and 032 Yoko would be highly recommanded as parcel, but
I am quite sure it will be a financial trap more than real difference on the road. ( I am not Schumacher on the road or on the circuit)
