摘要： A tyre noise damper (5) to be disposed in an annular tyre hollow formed between a wheel rim (3) and a pneumatic tyre (2) mounted thereon, the damper (5) being made of a flexible material and comprising a base (6) to be secured to the wheel rim (3) and at least one flap (7) extending from the base so that it may rise radially outwards from the wheel rim due to centrifugal force during running to block the annular tyre hollow. For example, the damper (5) comprises at least one annular elastic band (6) to be put around the wheel rim, the annular band (6) being provided by at least one U-cut (14) for forming a flap (7), and the base is formed by the remaining annular portion of the band. In another example, the damper (5) is made of a strip of the flexible material having a certain length, the base being formed by one end portion of the strip, and the flap (7) is formed by the remaining portion of the strip.

摘要： A pneumatic tyre comprises a tread portion (2) provided with a series of design-cycles repeating in the circumference of the tyre at variable pitches (L), wherein the number (NP) of different kinds of pitches is at least 10. The variable pitches (L) repeatedly increase and decrease alternately in one circumferential direction of the tyre to define start design-cycles from which the pitches (L) start to increase. A series of design-cycles is composed of a series of units (U), each unit (U) being defined as a group of design-cycles starting from and including one of the start design-cycles to but excluding the next start-cycle. The total number (NU) of the units is from 4 to 20. The units consists of at least one first-unit the number of which is 20 to 80% of the total number, at least one second-unit the number of which is 20 to 80% of the total number, and optionally a third-unit the number of which is 0 to 60% of the total number. The first unit is defined as including at least one pitch which is not less than a standard long pitch (PLa) and at least one pitch which is not more than a standard short pitch (PSa). The second unit is defined as including at least one pitch within one of the following two ranges, a range of not less than the standard long pitch (PLa) and a range of not more than the standard short pitch (PSa), but no pitch within the other range. The third unit is defined as all the pitches therein are more than the standard short pitch (PSa) and less than the standard long pitch (PLa). The standard long pitch (PLa) is the maximum pitch (PL) minus a length of 0.2 times a maximum pitch difference (MPD). The standard short pitch (PSa) is the minimum pitch (PS) plus a length of 0.2 times the maximum pitch difference (MPD), and the maximum pitch difference (MPD) is the maximum pitch (PL) minus the minimum pitch (PS).
