Quick question to everyone who sizes up from 17 to 18". What do you all do with the spare wheel in the boot? Do you buy an 18" spare as well or get an 18" space saver?
Makes no difference what size spacesaver you have as long as the rolling diameter is the same, if you look in your boot you'll find that the standard spacesaver spare in the S3 is actually an 18" wheel anyway.
