Abstract:
The present invention relates to a bicycle tire. More particularly, the bicycle tire is formed by foaming synthetic resin materials and is mounted to a rim of a bicycle, wherein the tire is prevented from being unexpectedly separated from the rim in use. That is, the bicycle tire (1) formed by injection-foam molding is characterized in that : a rim coupling portion (2) of the bicycle tire (1) is formed with a plurality of coupling holes (3) at predetermined intervals; and stoppers (4) formed of synthetic resin materials are fixed in the coupling holes (3), stopped by annular holding protrusions (6) when the tire (1) is mounted to the bicycle rim (5), and formed of arch surfaces (4a), horizontal surfaces (4b) and tilted both end surfaces (4c) so that the tilted both end surfaces (4c) are protruded when the stoppers (4) are fixed to the coupling holes (3). According to the bicycle tire of the present invention, the plurality of stoppers are maintained to be held by the annular holding protrusions when the tire is mounted to the bicycle rim. Therefore, the tire can be prevented from being unexpectedly separated from the rim by an impact and the like applied from the outside, thereby reducing the incidence of safety accidents during riding of the bicycle.
