The Van currently has 20" alloy rims on and R20 35 rubber and is really low. It just clears the kerb going up the drive. Im looking for some winter wheels and tyres but I reckon standard 16" 17" steelies will be so much of a smaller dimension even with bigger walled rubber that the van will hit the ground. Any ideas? Do the Toureg or the Vw pick up have 18" possibly 20"?
