Bought my Tyres august 2014.
Driven 2 1/2 seasons with them, or about 45 000km. Got 2.5mm left on all tyres.
Best with these tyres are following, Wet grip! WOW! Is the road even wet? Corners like the road is dry.
Responsivity, The tyre respons instantly to your steering!
Have even noticed that the new nano technology does not let the tyre to Scream when cornering hard or braking hard on hot Asphalt. :P
These are quiet when you have 5mm+ thread left, below that they become noisy.
I have pushed these tyres HARD with my Volvo S60 300bhp, the grip is so good that i cant get them to spin!
I am now looking after new tyres, but i cant see any other tyres compete with these in that price range! Going to order a new Set of these now! =)
