Abstract
A pneumatic tire includes: a pair of bead portions; at least one carcass layer extending between the pair of bead portions; a belt layer disposed on an outer side of the carcass layer in a tire radial direction; and a tire inner surface rubber layer constituting a tire inner surface. The tire further includes a linear conductive portion extending continuously at least from one of the bead portions to the belt layer and disposed on the tire inner surface rubber layer. The linear conductive portion is at least partially exposed to a tire inner cavity side and has a volume resistivity of less than 1×10{circumflex over ( )}8 Ω·cm.
Claims15
A tire, comprising:
- a pair of bead portions, each including a bead core;
- at least one carcass layer extending between the pair of bead portions;
- a belt layer disposed on an outer side of the at least one carcass layer in a tire radial direction;
- and
- a tire inner surface rubber layer constituting a tire inner surface;
- the tire further comprising a linear conductive portion extending continuously at least from one of the bead portions to the belt layer and disposed on the tire inner surface rubber layer;
- and
- the linear conductive portion being at least partially exposed to a tire inner cavity side and having a volume resistivity of less than 1×10{circumflex over ( )}8 Ω·cm;
- wherein
- the linear conductive portion
- satisfies a relationship between a distance Lc in a periphery direction of a portion of the linear conductive portion positioned between an edge of the belt layer and the one of the bead portions and an actual length Lrc of a portion of the linear conductive portion positioned between the edge of the belt layer and the one of the bead portions of 1.0<Lrc/Lc<3.0,
- satisfies a relationship between a distance La in the periphery direction of a portion of the linear conductive portion overlapping the belt layer and an actual length Lra of a portion of the linear conductive portion overlapping the belt layer of Lrc/Lc<Lra/La<8.0, and
- satisfies a relationship between a distance Lb in the periphery direction of a portion of the linear conductive portion positioned in the one of the bead portions and an actual length Lrb of a portion of the linear conductive portion positioned in the one of the bead portions of Lrc/Lc<Lrb/Lb<8.0.
