There's a decent thread in suspension area that covers many types of tyres. Unfortunatly opinions are like assholes and often wrong particuarly comparing tyres with different wear etc.
From my GTR with 266awkw and a no BS answer.
595-ss 255/40/17 Around town tyre, lacking in grip when you want to use the power. Around the track it was most evident the car suspension was out handeling the tyres. This size also lowers the speedo slightly but still within ADR.
Some Korean/chine tyre in 255/45/17, great match for actual speed on the speedo, unfortunatly the 595-SS are 10 times better and only about $50 more per tyre. ( I would worry about the name, except they are so bad)
595-RSR 265/35/18 Now these tyres make a dramatic improvement to steering and grip well above just upsizing the rim an inch. They are a bit slow to warm up and wet handeling is not super confident but all over far better then the 595-SS. For about $400-500 a tyre you can't go wrong. Most other big brand name Semi slicks are considered better from reading tyre comparo's but when you look at the pilot sport for $1000 a tyre, the Federals give a very good showing.
Conclusion, unless you have $4000 to spend on tyres, buy the Federal 595-RSR.
