    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.

    Abstract translation: 一种车辆用轮胎和用于从车辆轮胎散发热量的方法,其中所述轮胎具有侧壁,所述侧壁上的最上部区域,胎圈区域和内部层,所述内部层不可渗透空气,所述橡胶化增强材料的胎体, 胎体从侧壁的车辆轮胎的最上部区域延伸到胎圈区域中,并且通过环绕阻止延伸的胎圈芯而被围绕在胎圈区域中,橡胶胎面具有位于径向外侧的一个或多个胎面花纹沟,胎面 具有基部和槽侧面的槽,具有位于橡胶胎面和胎体之间的至少一个稳定带的带束加强件,包含橡胶增强物的稳定带,具有第一导热性的第一橡胶组合物和具有第一橡胶组合物的第二橡胶组合物, 第二导热率比第一橡胶组合物的第一导热率大至少约5%,第二橡胶组合物 所述第二橡胶组合物基本上填满所述胎面槽的基部和所述带束加强件的外侧层之间的空间,所述第二橡胶组合物基本上填充在所述胎面槽的基部和所述胎面槽的外侧帘布层之间的空间中, 当轮胎新时,第二橡胶组合物不与路面接触; 和/或第二橡胶组合物布置在轮胎的至少一个肩部的区域中,并且至少部分地与位于胎面下方的带加强件连接,第二橡胶组合物不与路面接触, 沿轴向延伸。
