Assembly of tire and rim



【課題】 操縦安定性、乗り心地性、騒音性能等の諸性能を調整可能とし、しかも該諸性能の向上を両立させる。 【解決手段】 タイヤ内腔H内に、タイヤ周方向にのびかつタイヤ軸方向に並列する第1、第2のタイヤチューブ4,5を配することにより、前記タイヤ内腔Hを、第1のタイヤチューブ4の内面が囲む第1の空気室11、第2のタイヤチューブ5の内面が囲む第2の空気室12、およびタイヤ内腔Hの内腔面HSと、前記第1,2のタイヤチューブ4,5の外面とが囲む第3の空気室13に区分する。空気室11,12,13は、空気バルブ17,18,19によって内圧充填可能であり、しかも前記第1の空気室11の内圧P1を、第2の空気室12の内圧P2より小、かつ第3の空気室13の内圧P3より大とした。 【選択図】 図2
PROBLEM TO BE SOLVED: To compatibly adjust several performances of steering stability, ride comfort, noise performance, etc and improve these several performances. SOLUTION: A tire inner cavity H is divided into a first air chamber 11 which an inner surface of a first tire tube 4 surrounds, a second air chamber 12 which an inner surface of a second tire tube 5 surrounds, an inner cavity surface HS of the tire cavity H and a third air chamber 13 which outer surfaces of the first and second tire tubes 4, 5 surround by arranging the first and second tire tubes 4, 5 extending in the tire peripheral direction and in the tire axial direction in parallel in the tire cavity H. The air chambers 11, 12, 13 can be filled with internal pressure by air valves 17, 18, 19, and the internal pressure P1 of the first air chamber 11 is made smaller than the internal pressure P2 of the second chamber 12 and larger than the internal pressure P3 of the third air chamber 13.
