TH58977B - Two tires Especially bicycle tires - Google Patents

Abstract

DC60 (05/02/47) This invention involved inflated two-wheel tires. In particular, bicycle tires, this tire must have at least a single layer of canvas (1), this canvas structure is secured by wrapping around the core of the rim (2) located in the rim of the tire (3). ) Made of rubber and supposed to have a rubber layer on the side walls (4) so that the two tires are more resistant to breakage and properties. Of good driving Suggested that the tire in new condition on the wall. Outside there is a surface layer (6), especially a rubber layer with a layer thickness of less than 0,5 mm, which this surface layer is resistant to. This surface layer (6) must at least cover the tread. (5) This invention relates to two inflated tires. In particular, bicycle tires, this tire must have at least a single layer of canvas (1), this canvas structure is secured by wrapping around the core of the rim (2) located in the rim of the tire (3). ) Made of rubber and supposed to have a rubber layer on the side walls (4) so that the two tires are more resistant to breakage and properties. Of good driving Suggested that the tire in new condition on the wall. Outside there is a surface layer (6), especially a rubber layer with a layer thickness of less than 0,5 mm, which this surface layer is resistant to. Against high tusks, this layer (6) must at least cover the tread (5).
