Subject: Re: Which Tyres on the Rapide?
The original tyres were crossplies, awful by modern standards. I'd propose there's no evidence to suggest that tyres affect values. The only point about radials whether Avon Turbosteel (which I use) or Michelin XWX is that you'll lose some rolling radius hence speed/revs. There are tyre comparison sites on the web which enable you to calculate the differences. On the Rapide I'd settle for HR rated tyres as good for 135 mph
