More Information
Summary:The invention provides a pneumatic tire which improves durability. The pneumatic tire (1) is provided with a reinforcing rubber layer (10) adjacent to the outer side of the folded-back section (6b) in the axial direction of the tire. The reinforcing rubber layer (10) includes a first rubber layer (11) and a second rubber layer (12) disposed on the outer side of the first rubber layer (11) in the axial direction of the tire. The loss tangent value (tan [delta] 1) of the first rubber layer (11) is smaller than the loss tangent value (tan [delta] 2) of the second rubber layer (12). 本发明提供充气轮胎，提高耐久性能。充气轮胎(1)配置有与折返部(6b)的轮胎轴向的外侧相邻的加强橡胶层(10)。加强橡胶层(10)包含第1橡胶层(11)和配置于第1橡胶层(11)的轮胎轴向的外侧的第2橡胶层(12)。第1橡胶层(11)的损失正切值(tanδ1)比第2橡胶层(12)的损失正切值(tanδ2)小。
