matter of tyre choice
I've always found the black, round one's work the best
Goodyear Eagle F1 Asym3 (latest) have the Asym2 on the TT, love 'em
Dunlop SportMaxx RT have these on the GTV, also great but they will be Asym3's when they are due renewal
Michelin Pilot Sports
Pirelli P-Zero's (just avoid P6000's)
Hankook Ventus Evo
Falken's are good if you are on a budget
UniRoyal Rainsport are supposed to be good, but wear rate is very high and side walls made of sponge cake
Basically any of the top brands will do the job...
Try looking on Tyre reviews, tests and ratings - Tyre Reviews
which gives you an overall % rating and comments.
Best place will be looking on You Tube for the Auto Car Tyre Reviews; bit more factual with the tests and comparisons they do.
As said, very subjective!
