Abstract
A vehicle tire and a method for dissipating heat from a vehicle tire where the tire has sidewalls, an uppermost area over the sidewalls, a bead area and an inner layer, the inner layer being impermeable to air, a rubberized reinforcement-containing carcass, the carcass extending from the uppermost area of the vehicle tire over the sidewalls into the bead area and being anchored in the bead area by looping around bead cores that are resistant to extension, a rubber tread having one or more tread grooves located radially outside, the tread groove having a base and a groove flank, a belt reinforcement with at least one stabilizer belt located between the rubber tread and the carcass, the stabilizer belt containing rubberized reinforcement, a first rubber composition having a first thermal conductivity, and a second rubber composition having a second thermal conductivity at least about 5% greater than the first thermal conductivity of the first rubber composition, the second rubber composition being arranged in the vicinity of the base of the tread groove and adjacent the groove flank of at least one tread groove, the second rubber composition substantially filling up the space between the base of the tread groove and an outside ply of the belt reinforcement, the second rubber composition not being in contact with a road surface when the tire is new; and/or the second rubber composition being arranged in the area of at least one shoulder of the tire and being connected at least partially with the belt reinforcement that is located beneath the tread, the second rubber composition not coming into contact with a road surface and extending in the axial direction.
