Has advantages such as the stiffness of the rules, the handling of the norms, the noise of the norms, and the holding of the norms; I found that riding the norms along the track similar to riding a tram, and I found that experience to be extremely enjoyable. Very balanced tire that was used on an Audi A5 all-wheel drive vehicle with a size of 245/40/18. Can be recommended. Negatives: It appeared to increase highway fuel consumption, however this could be due to the increased speed, as the tire provides confidence at high speeds. On the vehicle, it appears to be nothing more than a tire and has no further sporting connotations.
