The invention relates to the field of tires, in particular to a tire with improved controllability. The tire comprises a tread part, a sidewall part, a tire bead part, tire body cords, reinforcing sheets and outer protective rubber, wherein at least one layer of tire body cords extends to the tread part from the tire bead part through the sidewall part; the tire bead part is provided with bead filler, the tire side part is provided with tire side rubber, and the tire side rubber is connected with the outer protective rubber and the tire tread part; the reinforcing sheet is located between the tire body cord thread and the sidewall rubber, the upper end point of the reinforcing sheet is located above the tire body cord thread turn-up end point, and the lower end point of the reinforcing sheet is located below the apex end point; the thickness t5 of the reinforcing sheet is 0.6-0.8 of the thickness of the tire body cord thread, and the 100% modulus of the reinforcing sheet 5 is 3.12-12.5 MPa; the section height of the tire is H, the height h7 of the apex is equal to H * (0.15-0.25), and the 100% modulus of the apex is 5.0-20 MPa; the interface distance d6tb between the outer protective rubber and the sidewall rubber is 25-30mm, and the 100% modulus of the reinforcing sheet is between that of the apex and that of the outer protective rubber. According to the tire, the cornering rigidity of the tire is improved, and the comfort of the tire is kept.
本发明涉及轮胎领域,尤其涉及一种改善操控性的轮胎。该轮胎包括胎面部、胎侧部、胎圈部、胎体帘线、补强片和外护胶,至少一层胎体帘线从胎圈部经过胎侧部延伸至胎面部;胎圈部设置有三角胶,胎侧部设置有胎侧胶,胎侧胶连接外护胶与胎面部;补强片位于胎体帘线和胎侧胶之间,其上端点在胎体帘线反包端点上方,下端点在三角胶端点下方;补强片厚度t5为胎体帘线厚度的0.6~0.8,补强片5的100%模量为3.12~12.5MPa;轮胎断面高度为H,三角胶的高度h7=H*(0.15~0.25),三角胶的100%模量为5.0MPa~20 MPa;外护胶与胎侧胶的界面距离d6tb=25~30mm,并且补强片的100%模量介于三角胶和外护胶之间。该轮胎提高了轮胎的侧偏刚度,并且保持了轮胎舒适性。
