Ian,i think to be totally correct your car should have continental tyres(Anorak Oakley,sorry i mean Professor Oakley :lol: will probably point me out as wrong)I made extensive enquiries, when restoring my vert,for availability....They ceased production of the Continental 5.00 x 16 approx 15 years ago.
I have managed to find two of these N.O.S and one with approx 1K miles on it.Could not find another two to complete the set,so i used five new Avon tourist,i think these are as good a tyre as you will find.
So if anyone has two 5.00 x 16 continentals we could make up a set whether i buy or sell.
