To all you Scots, I will be moving to live near Inverness (Northside of Cromarty Firth) in a couple of weeks and have spent all my driving time (over 40 years) in London and South East. Do you recommend fitting winter tyres or is this unnecessary - would appreciate views !! Have a black edition B8 A4 Avant so 19" rims (255 x 35 x 19) what would I need for a winter tyre size / make to fit that rim. Any advice appreciated.
