Today I've been looking at winter tyres and found a list of ones approved by Porsche for 993s. Some of them in the list are not N rated!! It even says at the bottom of the doc words to the effect of "Tires must be N rated except for the ones that are not"[8|]
Given how few winter tyres are available for a given size of wheel I've decided to go for whatever's best rather than whatever P have got around to enrolling into their expensive tyre marketing program.[&:] It's not like I'm going to be tracking it on its winter tyres.
So - Seb - in same situation as you I think I'd put on the non-N pair of Sc2s
(Anyone got a set of winter tyres/wheels for a narrow body 993 they want to sell?)
