if they are the jap spec Advan 046s(check the sidewall if no load rating then they are jap spec) they are the best i use them on my track wheels,
great in the dry, not to clever in the wet.
go for a uk/euro spec for an all round softer sidewall tyre it also softens the ride in the car as well,
i run goodyear F1 GSD3s not the GSD1s.
its your own choice but stay away from cheapies :roll:
