I've just fitted P6000 on my w203 avantgarde and omg the road noise is too intrusive. I had some budget tyres before which were very quiet but these pirelli's are very noisy with a humming noise. I've noticed that there is wind noise coming from the windows too now. This has become more prominent with the tyre changes. I thought Pirelli's are market leaders? The grip is brilliant however.
Checked the tyre pressures? Some times tyre fitment centres over-inflate tyres to seat the new tyres on the rim and don't deflate to the correct running pressure?
You're joking right ? Not for nothing are these tyres known as 'ditchfinders' ..... there was another thread running on P6000s recently and everyone pretty much had had a bad experience on them !
My W203 was factory fitted with these Pirelli P6000s and I am glad to have got rid of them. Mine were 225/50.
