good question. wouldnt mind knowing that myself. Jusat hate thoe silly things they call spare wheels nowadays and not only that but i would be not at all please to spoil the apprearance of my lovy kuga with such an ugly thing.
I did consider a full size spare when we got our Kuga, but the depth would be too great for the space, so the carpet wont lie flat. A full size spare is not offered as an option, so you would have to pay full price for the appropriate alloy, then get the correct tyre fitted. Would be advisable to check the diameter for size too.
But it's the depth thing which is the real problem (and of course the carpet wouldn't fit back properly and it would all look very untidy). In the end I decided to live with the spacesaver,
even though I hate them.
