I have just bought a Volvo XC70 D5 SE and it has the space saver spare wheel and as I am traveling from East Sussex to Oxford on a cancer drug trial regularly I don't like the idea of having to use the the space saver and am looking for a full size spare. It s a 7.5J x18 ET55 and has a 235 / 50 R18 tyre. It doesn't need to have a tyre and doesn't have to match the one in the photo.... any help would be greatly appreciated
