ABSTRACT The present invention relates to a tire with noise-reducing main grooves and more particularly to a tire with noise-reducing main grooves for reducing resonance noise of the tire. The tire includes: a groove portion which is formed to extend circumferentially along a circumference of a tire tread; and a knurled portion which is formed on bottom and side surfaces of the groove portion. The knurled portion is provided to reduce noise energy by narrowing an air path formed when the groove portion and the ground contact each other. Date Recue/Date Received 2020-11-09

    ABRÉGÉ : La présente invention concerne un pneu à rainures principales de réduction de bruit, et, plus particulièrement, un pneu doté de rainures principales de réduction de bruit permettant de réduire le bruit de résonance du pneu. Le pneu comprend : une partie à rainures qui sétend le long de la circonférence de la bande de roulement; et une partie moletée qui est formée au fond et sur les surfaces latérales de la partie à rainures. La partie moletée permet de réduire lénergie sonore en resserrant le circuit dair créé lorsque la partie à rainures et le sol sont en contact. Date reçue / Date Received 2020-11-09
