Document Type and Number:
WIPO Patent Application WO/2021/111693
Kind Code:
A1
Abstract:
The present invention provides a tire in which it is possible to suppress reduction in wet-gripping performance and increased hardness before and after thermal aging. The present invention pertains to a tire having a tread formed from an elastomer composition containing a styrene-based elastomer and urethane particles, wherein the tread satisfies formula (1) below. (In formula (1), M100f represents the stress (23°C) at 100% elongation prior to thermal aging and M100a represents the stress (23°C) at 100% elongation after thermal aging.)
