Having sold all my M performance parts from my M135i ready for it to be part ex'd I only have a brand new set of winter tyres left, now being staggered two won't fit but two will so I could just buy two more and I'd have a set for the S3, anyone got any experience of the 8v on icy or snowy ungritted backroads like I have to face most Winters? Will it cope fine on standard tyres or would it be worth the cost of two tyres and going for winters come the cold season?
