I've been debating whether or not to buy this model after reading the reviews. I decided to just go for it, and now I don't regret it at all. Used only in the urban setting. When the roads are dry, it drives perfectly, and when they're wet, it's not much different (especially since I rarely go faster than 100 kilometers per hour in the city). There were no cases of hydroplaning in the puddles. 1=0; 2=60; 3=70; 4=95; balance. The disks' runout was measured on brand-new machinery before installation, and one disk was adjusted accordingly. Reasonably priced, respectable tires.
