Provided is a self-sealing tire having a sealing layer on the inner peripheral surface of the tire, in which when the self-sealing tire is attached to a standard rim and has an internal pressure of 250 kPa, the cross-sectional width and the outer diameter of the self-sealing tire are defined as Wt (in mm) and Dt (in mm), respectively, Wt and Dt satisfy the following inequality (1): 1600 < = (Dt2 * [pi]/4)/Wt < = 2827.4 (1); the sealing layer has a dynamic complex elastic modulus G * of 0.50-3.50 kPa as measured in accordance with ISO 13145 under the conditions of a strain of 100% and a frequency of 0.1 Hz in an atmosphere at 100 DEG C.
提供一种自密封轮胎,其在轮胎的内周面上具有密封层,其中,在自密封轮胎安装在标准轮辋上且具有250kPa的内压时的自密封轮胎的截面宽度和外径分别定义为Wt(单位为mm)和Dt(单位为mm)时,Wt和Dt满足以下不等式(1):1600≦(Dt2×π/4)/Wt≦2827.4(1),密封层根据ISO 13145、在100℃下的气氛中、在应变为100%和频率为0.1Hz的条件下测定的动态复弹性模量G*为0.50~3.50kPa。
