Tire for e.g. private vehicle, has self sealing layer with loss factor and dynamic modulus lower than inflation pressure, where loss factor and dynamic modulus are measured at ten hertz frequency, and layer covers portion of internal wall

摘要

The tire (1) has a crown (2) provided radially outside of a tire tread (8), and two sidewalls (3), whose internal surface and the crown forming an internal wall of the tire. A portion of the wall is covered by a self sealing layer (11) made up of styrene thermoplastic elastomer. The self sealing layer has a loss factor lower than the 0.2, and a dynamic modulus lower than the inflation pressure of the tire, for temperature ranging between 30 and 100 degree Celsius. The loss factor and dynamic modulus are measured at the 10 hertz frequency.
