PROBLEM TO BE SOLVED: To provide a tire, eliminating a spare tire to be an extra carrying weight and less effectively used as a natural resource, favourable in riding comfortability and being not suddenly and largely deformed as a pneumatic tire is, even when a foreign matter such as a nail, etc., intrudes into a tire part, and safe to continue to drive unless it is badly damaged. SOLUTION: By changing a unicellular elastic material to a multi-cellular elastic material by forming a part, which contacts with air of the pneumatic tire, into an independently divided small elastic material, a partial breakage, if any, is prevented to exert an influence upon the whole, to suppress the deformation of the tire to the utmost. Additionally, there are many other merits of easily filling the elastic material by making its shape spherical, easily deforming the spherical material and absorbing an impact load as a space is made between the spherical materials after filling, a easily lubricating the space as liquid and gas can pass the space, easily deforming and moving the spherical materials in a filling space as a contact area of the spherical material is small and friction is also small in comparison with the other shape, etc. Other merits of an inside protection after filling, a rotational balance improvement of the tire, etc., can be expected by leaving a proper amount of the liquid by using the liquid to fill a hollow part of the tire. |
