Since several thousand kilometers mounted, I am very satisfied. Thanks to the great diamond profile of Racer rolls very well, is very quiet and has thick rubber for many thousands of kilometers. Except for a flat tire by a mandrel there were no problems. For wet and dry conditions with good traction. For me, the perfect all-rounder (except for ice and snow) at an affordable price. Of the Schwalbe tires with rubber inserts for puncture protection, I can only advise against because of tough driving experience. Allen everyday drivers, who can do without extreme puncture protection, I can recommend this highly tires.
