It is rather silent, does not roll, and there are no issues when traveling at high speeds. The cost is really enticing in this case. A fantastic tire relative to its category. Con: After two years have passed, I am able to eat the review. Rubber, which provides a smooth ride, will sell for more than 40 to 50 thousand. It loses its effectiveness quite rapidly. Rolling is fairly difficult in the corners. Not appropriate for use while driving actively.
