发明名称 TYRE HAVING A BELT PLY WITH CORDS DISPOSED ALONG THE CIRCUMFERENCE OF THE TIRE TO REDUCE THE TIRE NOISE
摘要 <p>Tyre comprising a hooping reinforcement (100) which reduces the tire noise emission, wherein the axial distance between neighbouring portions of the hooping reinforcement is greater than or equal to 0.7 mm and smaller than or equal to 2mm, with the exception of one first axial region L1, the axial distance of each of the axial ends of the first axial region L1 from the median plane being greater than or equal to 0.05ˆ™S and smaller than or equal to 0.15ˆ™S, S being the maximum axial width of the tyre, and two second axial regions L2, provided on both sides of the median plane, each second axial region being centred at an axial distance D2 from the median plane, D2 being greater than or equal to 0.25ˆ™S and smaller than or equal to 0.4ˆ™S, S being the maximum axial width of the tyre, each second axial region L2 having an axial width W2 that is greater than or equal to 0.1ˆ™S, wherein the sum of the axial widths of the first and second axial regions being smaller than or equal to 0.5ˆ™S, wherein the difference between the average axial distance between neighbouring portions of the hooping reinforcement in the said first and second axial regions L2 and L2, and the distance outside the said first and second axial regions L1 and L2 is of at least 0.2 mm.</p>
