PURPOSE:To obtain solid tire of superior cushioning quality by using novel rubber material having very low hardness and high bounce impact elasticity. CONSTITUTION:The ring state core body 1 is coated with the cover 2, and anti- slipping grooves 2a are prepared on the tread of the cover 2, and lugs 2b are prepared in the opposit side to make the lug part 2b to be fitted on the rim 3. The ring core body 1 is made of vulcanized rubber having hardness of 30 deg. or lower by A type rubber hardness tester, or 15 deg. or lower by F type rubber hardness tester, and the coefft. of bounce impact elasticity of 50% or more. |
