245/35/17 tyre fitment + Dunlop sport SP9000

Hi,

I've just got myself a cracking deal on some Azev C's on zee german ebay. The advert did state that they made for the fiat coupe (4x98) but I'm unsure about the tyre size. They are fitted with 245/35/17 Dunlop sport tyres (2 x sp9000 2 xsp8000). Is this the correct tyre size & has anyone got any views on Dunlop sport tyres?

Thanks in advance.
