So final update.
Only when I got tyres replaced did I find the tyres that looked relatively new, with plenty of tread were also in fact manufactured in 2010. When I showed the sidewall defects I was told it was not pothole damage, so god knows how it got there.
Anyway the final result was an incredible transformation of the ride of the car with new tyres. It is so much smoother and compliant a ride. I had misinterpreted the harsh ride before to be all the fault of the suspension setup, where in fact although suspension needed tweaking the tyres had a large part to play.
So £215 well spent on 4 new Avon ZV7’s (plus fitting). Result
Very interesting. I have 2009 tyres and have been resisting a change as they have only done 7000 miles. With this perspective I think I will fit a new set. Our local ATS says that they have the right equipment and the chirpy chap quoted a few wire wheeled cars they have supplied in past weeks, E Type, MGB.
New Avon ZV7s fitted by ATS today, my oh my what a difference. I resisted changing the tyres as the old set were virtually unused, now my advice to anyone is don't hesitate' go ahead. The ride is far better, more forgiving and they seem to work with the suspension rather than crashing through the bumps. i went for 205 65 15 and while they look a little bulky I'm glad I did. ATS were very good, took 45 minutes, wheels in perfect balance, weights now fitted to the inside of the hubs
Had a good long chat to Richard, an ex Plus 8 owner of 16 years and member/organiser of Hopmog (who was in for a tyre fitting for a Mercedes). great to hear his reminiscences of touring around Britain.
Much appreciate all the good advice once again
