    • A pneumatic tire includes a tread portion (2) provided with a pair of shoulder main grooves (3) and at least one crown main groove (4) between the shoulder main grooves to define a pair of middle portions (6) between the adjacent shoulder main groove and crown main groove. The middle portions are provided with inner middle lug grooves (12) and outer middle lug grooves (11). Each outer middle lug groove extends from the shoulder main groove to its axially inner end (11e) while decreasing its groove width. The outer middle lug groove are arranged with alternately arranged first pitches P1 and second pitches P2, wherein the second pitches are larger than the first pitches. Each inner middle lug groove extends from the crown main groove to its axially outer end (12e) while decreasing its groove width. The inner middle lug grooves are arranged with substantially the same pitches P3.
    • 本发明提供一种充气轮胎,该充气轮胎包括设置有一对胎肩主沟槽(3)和位于胎肩主沟槽之间的至少一个胎冠主沟槽(4)的胎面部分(2),以在相邻的肩部之间限定一对中间部分(6) 主沟和冠主沟。 中间部分设置有内部中间横向花纹沟(12)和外部中间横向花纹沟(11)。 每个外部中间横向花纹沟槽从胎肩主沟槽延伸到其轴向内端(11e),同时减小沟槽宽度。 外侧中间横向花纹沟以交替排列的第一节距P1和第二节距P2布置,其中第二节距大于第一节距。 每个内部中间横向花纹沟槽从胎冠主沟槽延伸到其轴向外端(12e),同时减小其沟槽宽度。 内部中间横向花纹沟以大致相同的间距P3布置。

    • A wheel assembly (22) includes a rigid wheel (30) and an airless flexible tire (32) with certain performance characteristics of a pneumatic tire. The rigid wheel (30) includes a central portion and a plurality of circumferentially spaced mounting elements removably attached to a radially outer margin of the central portion. The tire (32) is mounted on the wheel (30) and engages the mounting elements such that portions of the tire not engaging the mounting elements are separated radially from the wheel (60) by a space. The tire is configured such that portions of the tire not engaging the mounting elements flex inwardly toward the wheel when subject to ground engaging pressure, thereby minimizing ground penetration and soil disruption. The tire may include one or more tension elements embedded in the tire to increase the tire's strength and resilience.
    • 轮组件(22)包括刚性轮(30)和具有充气轮胎的某些性能特性的无空气柔性轮胎(32)。 刚性轮(30)包括中央部分和多个周向间隔开的安装元件,其可移除地附接到中心部分的径向外边缘。 轮胎(32)安装在轮(30)上并与安装元件接合,使得不与安装元件接合的轮胎的部分与轮(60)径向分开一定空间。 轮胎被构造成使得当接触地面接合压力时,未接合安装元件的轮胎的部分向内弯曲,从而最小化地面穿透和土壤破坏。 轮胎可以包括嵌入在轮胎中的一个或多个张紧元件,以增加轮胎的强度和弹性。

    • A solid rubber tyre for vehicle wheels is realized to comprises an annular band (1) made of a deformable material - rubber, in particular, into which there is embedded a ribbon-like element (5) formed in such a way as to have its generatrices substantially parallel to the axis of said band, and in such a way as to separate internally, the layers (6) of deformable material having a thickness (s)- measured in the radial direction, that is lesser than 80% the minimum width (1) of the band itself - measured in the direction of said axis; said ribbon-like element (5) having a thickness (s') lesser than 20% the said layers' thickness s, with presenting (when the ribbon-like element is disposed in a substantially plane configuration) a modulus of elasticity- at least in a direction contained on the plane of the said configuration, that is at least greater than ten times the modulus of elasticity of the deformable material.
