Thanks John.
I have had Michelin Primacy Tyres for the first 248,000 miles on my W210 Estate. I rate them highly.
I have replaced them with Maxxis All Weather Tyres which given the mileage, type of driving, cost and age of the car are fine for me. I have Kumho All Weather Tyres on the Lexus GS. They are also fine for me. For me, Tyres are a compromise between cost and capability, but I must have a quiet Tyre. Many cars are constructed relatively poorly and noise is generated by the Tyres and reverberates through the vehicle contributing to tiredness and headaches etc.
Ford had NVH until recently..Noise, Vibration and Harshness and I could identify with its attempt to reduce the total NVH within its cars.
