FIELD: machine building.SUBSTANCE: elastic car tyre (1) includes tire air chamber. This chamber is surrounded by tire tread (2), tire bearing race (3), and adjacent to tread (2) side walls (4, 4.1). In tyre chamber there is noise absorbing insert (9) or located inside tyre noise absorbing structure. Between noise absorbing insert (9) or noise absorbing structure and inner side 10 of tread 2, thus being adjoined to inner side (10) of tread (2), tire bearing race (3), is propagating along circumference of tire tread (2) ventilation layer (13) with structure which is permeable for air at least in crosswise or lengthwise direction relative to tire tread (3). This layer is capable of transmitting air flow, at least partially in contact with inner wall (10) of tread (2).EFFECT: technical result is improvement of heat removal from inner side of tire tread.14 cl, 9 dwg |
