The invention belongs to the technical field of tires, and particularly relates to a tire shoulder stepped heat dissipation groove. Tire shoulder stepped heat dissipation grooves are evenly formed inthe circumferential direction of a tire shoulder wing part, the stepped heat dissipation grooves comprise the first heat dissipation groove and the second heat dissipation groove, and the second heatdissipation groove is formed in the center of the first heat dissipation groove, wherein the width of the first heat dissipation groove is greater than that of the second heat dissipation groove, andthe depth of the first heat dissipation groove is less than that of the second heat dissipation groove. The stepped heat dissipation grooves can meet the heat dissipation requirement and also have thestone removal, puncture resistance and tear resistance, the stepped design enables the groove width to be larger, heat dissipation is facilitated, the tire shoulder part has certain buffering when encountering larger shearing force, tearing is not likely to happen even though a groove opening is deep; meanwhile, stone removal is facilitated through the stepped groove design, a tire shoulder framework structure is not easily stabbed, and safety and attractiveness are better achieved.

    本发明属于轮胎技术领域,具体涉及一种胎肩阶梯式散热槽。本发明的胎肩阶梯式散热槽沿胎肩翼部圆周方向均匀设置,所述阶梯式散热槽包括第一散热槽和第二散热槽,所述第二散热槽设置于第一散热槽的中心部位,第一散热槽的宽度大于第二散热槽,所述第一散热槽的深度小于第二散热槽。本发明的阶梯式散热沟槽既可以满足散热又兼顾排石、耐刺扎、抗撕裂性能,阶梯式设计使得槽宽更大,便于散热,胎肩部位在遇到更大的剪切力时有一定的缓冲,即便是槽口较深也不容易撕裂,同时阶梯式的沟槽设计方便排石,不易刺扎至胎肩骨架结构,更具有安全性和美观度。
