After one year and 40K km, I have positive impressions of these tires. They are not at the top of the UHP category (e.g. the PS4 I had before), but they are close to it and almost half the price. They are better than any touring category. I mean, while they are cheap tires, they do not fall behind the top ones as much as the price difference suggests. Excellent in dry conditions with good balance (the XL ones with reinforced sidewalls), very good in wet conditions without strong hydroplaning, but slightly weaker in wet braking (ABS activation), really quiet, Treadwear 320 still have 5mm tread, low rolling resistance, four years warranty(!), and made in Germany. Also, their performance decreased quite a bit after 30K km compared to the PS4, which provided confidence even at 40K km. They will satisfy even the "worried" drivers. The above concerns personal evaluations. The car is a Volvo V50 D2.
