I have no evidence of this but have always thought that OE tyres on all my new cars over the years did more mileage than replacement tyres , exactly the same make, rating etc. Any truth in this view ? I’m happy if new tyres are better at reducing punctures, so les need for bulky spares but I have not experienced any noticeable reduction and feel more comfortable having a spare or run flat. I have always felt good tyres are vital as it’s the only thing between the car(you) and the road and at high speeds comforting. MM PS Is there a thread/topic on the site that covers and recommends car cleaning and detailing products - not just for Morgans but for our other cars. I have real difficulty in wheel cleaning and plastic trim ( eg back to black) etc etc.
