摘要： A pneumatic tire comprising a tread portion which comprises a surface rubber layer which is disposed in an outer portion of the tread portion in the radial direction of said tire and has a specific resistance of 108 &OHgr;·cm or more after curing by vulcanization and conductive rubber members which comprise a rubber composition having a specific resistance of 106 &OHgr;·cm or less and replace a portion of the surface rubber layer, wherein the conductive rubber members are disposed in portions of the surface rubber layer extending from the outer surface to the inner surface in the radial direction of said tire discontinuously in the circumferential direction of said tire at the outer surface of the surface rubber layer in the radial direction of said tire, is provided. The pneumatic tire shows not only an excellent effect of static discharge but also excellent durability.

摘要： A pneumatic tire comprising a silica-rich compound tread provided with an antistatic conductive rubber layer has improved safty based on durability and extrusion productivity. In this tire, the silica-rich compound rubber layer is divided at at least one portion in a width directional of the tire by a conductive rubber layer extended in a circumferential direction substantially over the whole thickness of said rubber layer. In this case, a thickness direction distance a in a width directional section of said rubber layer and an edge face length b of a divisional rubber layer consisting of said conductive rubber layer in a width directional section satisfy a relation formulated by the following expression, a

摘要： [Subject] To provide a pneumatic tire whose snow performance is improved without affecting its dry performance.[Measures for Addressing the Subject] Step portions 22F and 22R that are continuous so as to protrude respectively from step-in sides and kick-out sides of each of blocks 20 configuring a tread portion 16 are disposed in a pneumatic tire, and the step portions 22 are disposed in a staggered manner in the tread portion 16. Thus, even when the step portions 22 are disposed, the rigidity of the blocks 20 does not decline that much and dry performance is not affected that much. Further, snow performance can be improved by the edge pressure of the step portions 22.
摘要翻译： [主题]提供一种在不影响其干性能的情况下提高雪地性能的充气轮胎。 [处理对象的措施]分别从构成胎面部16的块20的逐个侧面和踢出侧分别突出地连续的台阶部分22F和22R设置在充气轮胎中，并且台阶部分22以交错方式设置在胎面部分16中。因此，即使设置台阶部22，块20的刚性也不会下降，干性能也不会受到太大的影响。此外，可以通过台阶部分22的边缘压力来提高雪的性能。
