Tire with flow field for blocking sound waves by forming fluid isolation layer in tire cavity to reduce noise during tire rolling

The present invention mainly provides a tire with flow field for blocking sound waves, which is to arrange a plurality of diversion lines on the inner cavity surface of the tire. In which, the tire includes a tread, a shoulder, a sidewall and a tire bead. The diversion lines are integrally formed during vulcanization of tire. When the tire is rolling, the gas in the tire cavity may pass through the surface of a single diversion line. Due to the cross section design of diversion lines, the gas may start flowing along surfaces of diversion lines and then passing the adjacent next diversion line. Because the airflow passes the surfaces of diversion lines, a fluid isolation layer that is continuously flowing is formed in the tire cavity, so that the noise generated by tire rolling cannot be effectively transmitted, thereby reducing the noise generated during tire rolling.
