Claim:
1. A vehicle tire comprising: a tread portion and a package of rubberized reinforcement layers arranged radially inwards from the tread portion, the tread portion comprising a tread rubber layer that provides a ground contacting surface and is disposed in a radially outward part of the tire, and a tread base rubber layer arranged radially inwards from the tread layer, the tread portion further comprising at least one rubber member that extends in the radial direction of the tire from the ground contacting surface to at least one layer of the reinforcement package, the rubber composition of the tread rubber layer having an electrical resistivity at room temperature of more than 10 the rubber composition of the tread base rubber layer having an electrical resistivity at room temperature of between 10 the rubber composition of the at least one rubber member having an electrical resistivity at room temperature of less than 10 the rubber composition of the at least one layer of the reinforcement package having an electrical resistivity at room temperature of less than 10
