RobUK, your suspicion was correct about the Continentals not being Run Flats, They had ordered a Mobility Kit for it but they hadn't explained that too me. So I have insisted that I have the Bridgestone Blizzaks instead which they are going to order for me and send the Continentals back! Was a little surprised they had ordered them as they car isn't due until the middle of december and I haven't even paid for the Winter Tyre package yet so there was no order form for them!!
Many thanks for making it aware to me otherwise I wouldn't have known.
