  • Patent number: 11648806
    Abstract: At least one mark formed by a character or a figure and a surface geometry arrangement region disposed adjacent to the mark outside the mark can be formed on a surface of a sidewall portion of a tire. The surface geometry arrangement region can have a plurality of micro projections. The surface geometry arrangement region can include a first region formed in at least a part of the surface geometry arrangement region such that the greater a distance from the mark is, the less a height of the micro projection can be.

  • Patent number: 7712498
    Abstract: A flat tire (2) according to the present invention includes a load support layer (12) positioned on an inside in an axial direction of a sidewall (6). The tire (2) further includes a belt (14) constituted by an inner belt ply (40) and an outer belt ply (42), and a full band (16) substantially covering a whole surface on an outside in a radial direction of the belt (14). The full band (16) is formed by a cord and a topping rubber. When a tensile load of 50N is applied, the cord has an elongation of 3.0% or less. The tire (2) may include a center band which has a smaller width in the axial direction than the width of the full band (16) and is laminated on the full band (16) in the vicinity of an equator (CL).
