    • A pneumatic tire for a two-wheeled vehicle, including a pair of sidewalls, a tread, a carcass, bead rings embedded in radially inner ends of the pair of sidewalls and stiffeners including tapered rubber fillers. According to the invention, the tire comprises a belt layer between the tread and the carcass. The belt layer consists of at least one ply whose width is at least 0.5 time of a width of the tread. Cords of the ply have a modulus of elasticity of at least 600 kg/mm.sup.2 and are arranged substantially in parallel with an equatorial plane of the tire.The tire according to the invention maintains a hoop effect of the belt layer to sufficiently exhibit characteristics as a radial tire and eliminates an extreme difference in bending rigidity in radial directions over from the tread to the sidewalls to obtain smooth turning of the two wheeled vehicle at a corner.

    • A pneumatic tire having an excellent cut resistance is disclosed, which comprises an annular crown portion constituting a tread, a pair of side portions supporting said crown portion, a pair of bead portions located at each foot of said side portions for fitting to a rim, a carcass layer composed of at least one rubberized cord ply toroidally extending between said bead portions and a liner layer disposed indise and adjacent to said carcass layer.In the tire according to the invention, a fault surface having an extremely low adhesion which intercepts the crack growth from the outside of the tire is further arranged in said liner layer at at least a part of a region extending between said bead portions.In the other tire according to the invention, for intercepting the crack growth from the outside of the tire, a low modulus middle rubber layer composed of rubber having a modulus lower than that of the adjoining rubber is further arranged in the tire at at least a part of a region extending between said bead portions.The growth of the cut damage especially given to the side portions of the tire is prevented by the fault surface or the low modulus middle rubber layer.
    • 公开了一种具有优异的切割阻力的充气轮胎,其包括构成胎面的环形冠部,支撑所述冠部的一对侧部,位于所述侧部的每个脚部的一对胎圈部分,用于装配到轮辋, 胎体层,其由在所述胎圈部之间环形延伸的至少一个橡胶帘线层和与所述胎体层相邻且相邻设置的衬垫层组成。 在根据本发明的轮胎中,在所述胎圈部分的延伸区域的至少一部分上,在所述衬里层中进一步布置具有从轮胎外侧截取裂纹扩展的具有极低粘附力的故障表面。 在根据本发明的另一轮胎中,为了从轮胎的外侧截取裂纹扩展,在轮胎中还至少设置了一个低模量中间橡胶层,该橡胶层的模量低于相邻橡胶的模量 一部分在所述胎圈部分之间延伸的区域。 特别是轮胎侧面的切割损伤的生长由于断层面或低模量中间橡胶层而被防止。
