My 1982 280zx still has a set of Denovo run flats fitted to the original wheels.The size of the tyres are 200/65/HR370. As you will realise, for safety, these probably ought to be consigned to the Dunlop museum!! Can anyone advise on a modern equilivant or best option. I would like to retain the original wheels as they are in excellent condition. Thanks in anticipation. Norfolk Dave.
