Let's talk bout the max performance tyres first. These are:
Goodyear Eagle F1 Assymetric. While the reviews on these tyres have generally been excellent the size I want is made in the PRC. My tyre supplier adviced me not to go for PRC ones. The made in Germany ones are 225-45 17" but these (gulp) cost RM600+
Dunlop SP Sport Maxx TT. These are made in Japan and like the Goodyear F1 Assys are also assymetrical in design and feature Kevlar fibre reinforced sidewalls.
And now for the extreme performance and near semi-slick the famed Federal 595 RS-R. I can get these @ pretty reasonable price but '09 stock and there are exactly four left. The new 2011 stock is expected to cost substantially more and way above my budget. Threadwear is quoted as a wallet busting 140 but one can never compare UTQG ratings from different tyre manufacturers. A tyre from another manufacturer with the same rating can be softer or harder. However one things for sure, compared to the above two tyres the 595 RS-R will give more dry grip and steering response but at the expense of NVH, tyre wear and wet weather grip.
