I have just bought winter tyres for my S-Max and of course these do not come in Run Flat. So i now have the problem of sourcing a space tyre/space saver as a back-up over the winter. Has anyone found out a suitable option with this, or is the only way to buy a full-size replacement tyre (to satisfy insurers etc) and then take up 1/2 the boot space. Did anyone ever get an answer from Ford???
