A pneumatic tire is provided with a support structure supporting the load from the vehicle, which is provided with: an inner ring; an outer ring, which is concentrically arranged on the outer side of the inner ring; and a plurality of connecting parts, which connect the inner ring and the outer ring, and are independently located on the circumference of the tire. The plurality of connecting parts are arranged as follows: the first connecting part of the strip shape and the second connecting part of the strip shape are arranged along the tire circumference, and the first connecting part extends from one side of the tire width direction of the inner ring to the other side of the tire width direction of the outer ring, and the second connecting part extends from the other side of the tire width direction of the inner ring part to the other side of the tire width direction of the outer ring part. The first connection part and the second connection part are thicker than the width of the tire, and the thickness direction is toward the circumference of the tire. The first connection part and the second connection part observed from the circumference of the tire are at the radial inner end of the tire or the radial outer end of the tire. The first connection part and the second connection part have the width of the plate and the radial central part of the tire. In comparison with the enlarged reinforcing part, the surface area of the inner radial end of the tire including the reinforcing part and the outer radial end of the tire can be summed up as follows: the surface area of the radial central part of the tire is more than the surface area of the inner radial end of the tire.

免充气轮胎
本专利技术涉及一种具备对来自车辆的载荷进行支撑的支撑结构体而作为轮胎结构部件的免充气轮胎(non-pneumatictire),涉及一种希望可以代替充气轮胎进行使用的免充气轮胎。
技术介绍
作为现有的免充气轮胎,例如,存在有实心轮胎、弹簧轮胎、缓冲轮胎等,但是,都不具有充气轮胎的优异性能。下述专利文献1中记载有一种免充气轮胎,其中,将环状的外周部件与内周部件之间用辐条连结起来,至少所述辐条具有由橡胶或树脂形成的辐条结构体,并且至少在所述辐条的径向表面贴附有金属层。通过在辐条的径向表面贴附金属层,使得辐条在径向上的刚性增加,从而提高载荷支撑能力,并且,随着载荷支撑能力的提高而抑制轮胎旋转时的变形,因此,能够减少发热,降低滚动阻力。另外,下述专利文献2中记载了一种免充气轮胎,该免充气轮胎具备:内侧环状部;外侧环状部,其呈同心圆状地设置于该内侧环状部的外侧;以及多个连结部,它们将所述内侧环状部和所述外侧环状部连结起来,且在轮胎周向上分别独立地设置。多个连结部构成为:长条板状的第一连结部和长条板状的第二连结部沿着轮胎周向排列,其中该第一连结部从所述内侧环状部的 ...
