I am not an expert (and who is anyway!). Approximately 10k kilometers and 1 year with these specific front tires, on a "heavy" medium family car with 120 horsepower. I don't make sharp turns, and I never drive recklessly, so I have never felt any lack or any other issues that reckless drivers mention. In everyday driving, on the glassy roads of Attica, in wet conditions, in panic braking, but also at high speeds (well above the limit) on the highway, etc., no complaints. The choice was made after comparing with other budget tires, and they are perfect for my needs. Soon, the rear tires will also be replaced with these specific ones. In my opinion, if you don't have a really powerful vehicle, or if you don't go on a racetrack, they will suit you just fine.
