I've been using these tires for almost 20000 kms. Good grip, tires have good wear. Rolling resistance a bit high, because my fuel consumption went up since I used these tires (tires on 2,4 bar). Very good price quality (in size 195/55 15"), other premium brands cost 100 EUR/ tire, for this I only paid 75 EUR.
I didn't want to put el cheapo chinese brands under my car, and I didn't want to pay premium (car is only used for town, and with a very easy going driving style, I don't think expensive tires are necessary). In other sizes the pric difference might be smaller (like in 195/65 15"), in that case I would buy the premium brand (only 10EUR difference).
Would definitely buy them back in this size.

Bought these for a Volvo 240, mostly because the choice is limited - the car need small tires with a heigh weight index. Excellent tires! Silent, good grip in all conditions, and even cheap. Buying them again for two other cars just now.
