If you want change from 18 inch tyres to 17 inch you would probably need to change your wheel size as well, i.e. a set of new wheels!
Check if you have 17 or 18 inch wheels, if it is an SE then most likely 17 inch and if it's an Elite or Ultimate, most likely 19 inch otherwise they will be 18s. The size of your tyres will be on the sidewalls which will be the size of winter tyres you need I assume. I don't know anyone though in the UK who changes their tyres for the winter, but I guess some do.
