Document Type and Number:
Japanese Patent JP2023096686
Kind Code:
A
Abstract:
To provide a tire having improved crack resistance performance.SOLUTION: A tire includes a tread and an inner liner. The inner liner is formed of a rubber composition containing a polymer component. A distance G from a crown part of the tread to a tire inner cavity surface is 9.0 mm or less. An elongation at break (80°CEB) of the rubber composition measured under a condition of a temperature of 80°C and a tension speed of 3.3 mm/sec, a loss tangent tanδ (70°Ctanδ) of the rubber composition measured under a condition of a temperature of 70°C, a frequency of 10 Hz, an initial strain of 10%, and a dynamic strain of ± 2.5%, and G (mm) satisfy the following expressions (1) and (2): 80°CEB/70°Ctanδ≥2600...(1), 80°CEB/G≥40...(2).SELECTED DRAWING: None
