Hi Tony,
We've been in contact on this subject recently. Other than the MRF tyres, the only new production tyres available to my knowledge are made by Alliance in Israel. They have some sort of highway pattern. See Dirk Leegwater's site (
http://www.lwdparts.com/) for a picture and details.
Like Mike said, safety comes before looks - ask Mike Ebeling who had two blowouts on his freshly restored Ford WOA2A Heavy Utility on his way to Beltring this year.
Mike Ebeling is not in the internet, so I'm helping him to find a source for 9.00-13 tyres.
Who knows of where he can get them in the UK, or knows of anyone abroad willing to ship to the UK?
Regards,
Hanno
