充气轮胎
摘要：
本发明提供一种在维持较低的滚动阻力的同时能够较好地防止路面和轮胎之间产生静电、使用时的安全性得到进一步提升的充气轮胎(1)。分别形成为胎面部(2)、缓冲层部(6)以及胎侧部(3)各自所形成的胎面胶、缓冲层胶以及胎侧胶的体积固有电阻均在1×108Ω·cm以上，在构成上述胎体的帘布层和上述胎侧胶之间形成有体积固有电阻小于1×108Ω·cm且厚度在0.2～2.0mm范围内的导电层(9)，同时，在轮胎表面，露出有导电层(9)以及与导电层(9)相接、其体积固有电阻小于胎面胶的橡胶粘合层中的至少一个。
摘要（英）：

The objective of the present invention is to provide a pneumatic tire that can desirably prevent generation of static electricity between the road face and the tire, while maintaining a low rolling resistance, so that the safety in use is further improved. In pneumatic tire of the present invention, each of tread rubber, breaker rubber and sidewall rubber that are respectively formed on a tread section, a breaker section and a sidewall section has a volume resistivity of 1x10<8 >Omega.cm or more, with a conductive layer having a volume resistivity smaller than 1x10<8 >Omega.cm and a thickness in a range from 0.2 to 2.0 mm being formed between a carcass ply forming the carcass and the sidewall rubber, and at least either conductive layer or a rubber cement layer that is formed so as to be made in contact with conductive layer and has a volume resistivity lower than that of the tread rubber is exposed to the surface of the tire.
