Not sure whether you can but definitely worth asking. To be honest I never even considered the ground clearance as this is my third Morgan and I never had any problems with the ground clearance on the first two, including trips to France and using the same garage etc. If I had known or thought about it I would have considered different wheels as the alloys and larger, 16", wires both give you more clearance.
Morgan quote the same clearance for all trads, obviously not correct, and the first I knew my car was different was driving it back from the dealer on familiar roads and crashing into speeds humps that had previously posed no problems and then almost not getting it into the garage.
