    Abstract: The wheel (1) comprises a rim (2) and a hub (3) between which a plurality of spokes (4) are connected. The rim has a radially recessed, cylindrical outer surface (2a-2d) with a channel-shaped cross-section and is provided with a plurality of drilled seats (6) each intended for the attachment of a respective nipple (5) for the connection of a spoke (4). Annular sealing members (13) are provided between each nipple (5) and the corresponding drilled seat (6) of the rim (2).The wheel (1) further comprises a circumferential, band-like seal (14) which is made of resilient material, is fitted on the rim (2), and extends over the recessed cylindrical surface of the rim (2) in a circumferentially stretched condition so as sealingly to cover all of the drilled seats (6).

    Abstract: A pneumatic tire comprising a skin layer which is formed by curing a polyurethane resin composition comprising a compound having active hydrogen atoms and an organic polyisocyanate compound, has an oxygen permeation coefficient at 23null C. under a relative humidity of 60% of 2.0 mlnullmm/m2nulldaynullMPa or smaller and comprises 20% by weight or more of a skeleton structure represented by formula (1) is provided. Since the tire has the skin layer formed with the polyurethane resin composition and having an excellent barrier property to gases, the weight of the tire can be decreased, durability can be improved and quiet driving can be achieved while the internal pressure is retained even when the gas filling the tire is the air, and the tire is more economical than tires filled with nitrogen gas. Unlike other tires using other materials having the barrier property to gases to decrease the weight, no adhesives are necessary for disposing the skin layer. Thus, the process can be simplified and the cost can be reduced in the production. 1

    Abstract translation: 包含通过固化包含具有活性氢原子的化合物的聚氨酯树脂组合物和有机多异氰酸酯化合物形成的表皮层的充气轮胎在相对湿度为60％的2.0ml的条件下具有23℃的透氧系数。 mm / m 2·day.MPa以下，由式（1）表示的骨架结构体含有20重量％以上。 由于轮胎具有由聚氨酯树脂组合物形成并具有优异的气体阻隔性的表皮层，所以即使在内部压力保持时也能够减轻轮胎的重量，提高耐久性，并能够保持静音，同时， 填充轮胎的气体是空气，轮胎比装有氮气的轮胎更经济。 与使用具有气体阻隔性的其他材料以减轻重量的其它轮胎不同，不需要粘合剂来设置表皮层。 因此，可以简化该过程，并且可以在生产中降低成本。
