I'm still using the factory-fitted Michelin ES tyres after 35,000 miles, although the fronts are down to 3-4 mm. However, I recognise that I am a defensive driver, which has kept me out of trouble over 60 years. These tyres have lasted much longer than the Dunlops fitted to my Mk 2 Jazz, where the fronts needed to be replaced after 25,000 and 50,000.
