I purchased this rubber based on online reviews as the ideal balance between cost and performance. Everything would be good, but the continuous howl (similar to the hum in an airplane) destroys the experience at a speed of 30 to 60 km/h, and this fact is really aggravating. The second thing is how smoothly you stay stationary (on snow and ice), and despite the fact that all of the spikes are still in place, the rubber tries to slip into slip. The tires on our deteriorated roads are quite soft, so drive carefully! I crashed into a pit at 30 km/h, puncturing the wheel and tearing out a 4-5 centimeter portion of the tire in the process.
