New tyres time :-(

[awolfinsheepsclothes]

Now the sun is here it's time to take of the winter tyres Dunlop sp winter 3D fantastic and I recommend them. So I went down to a oldham part worn dealer and went through his stock with my mate a Ex ATS tyre fitter who looked after my tyres for over 20 years. but couldn't find even one I was happy with even though the vendor tried to convince me they where all good. Wrong speed rating W instead Y and he didn't even know what a y rating was? And they all had punctures when he said they haven't . Good tread and Bridgestone and continental though.
So I think I'll have to go for new I had Goodyear eagle F1s on my last car and they where brilliant in the wet or dry but didn't last and they don't make the same model anymore. Summer tyres last year where michelin pilot sport, grip wasn't brilliant and mileage wasn't amazing so I wouldn't want them again,
I was thinking about michelin pilot super sports after Amar's recommendation so got a price from ATS of £750 fitted all in and £50 fuel voucher back.
And £700 fitted all in from Profit tyres in Oldham.
Anyone else have better idea???
My tyres are 245/45/18 96y by the way
Also what is the top speed of a D2 40valve autocar road test 15 September 1999 says 159 mph suggesting there is no 155mph speed limiter. Do S8s have speed limiters has anyone tested the top speed on the autobahn?? Or GPS verified it?
Thanks Dave
