Note that this review is for when I had these tires on my Skoda Fabia 1.6 105 bhp which I eventually sold.
Good:
Very good quality material used. Did maybe 8000 miles before I sold the car & they still looked like new
Very stylish design. Best looking tire I have seen.
Quiet. Could not notice any road noise.
Good grip in dry weather.
Bad:
Very expensive & poor for their performance. See the below points.
Suffers badly from wheelspin in damp & wet weather. I had these on the front & even when I wanted to accelerate away a bit quicker than normal, the wheels would go into a spinning frenzy. My Fabia was hardly a monster & nor did I go around like a boy racer, but for the price I paid I would have gone for a budget make instead which would have had the same issues & saved a lot of money.
Driving in the rain felt like I was on ice. No feel at all.
Can make the steering tramline. Not the worst I have experienced, but again not impressed.
Overall:
For the price I cannot recommend these. I got two Goodyear F1 AS2s, stuck them on the front & the Pirellis on the back. The difference was much better. No wheelspin, fantastic in the wet, & good road feedback. The only thing is that the Goodyears were softer than the Pirellis & looked more visibly worn out but gave a lot more confidence in all driving conditions.
