Ad08R are great, almost a perfect tyre IMO. Not brilliant when its really wet but they have never put me in a dangerous situation, and shouldnt do unless you drive like a dick in the rain
still get he PSS but very expensive in the 92 rating, cheaper on the 88 rating, but apparently the PS4 is a better tyre than the PSS n 95% of situations ie not on a dry track with some heat in them but presumably better in all UK road situations
