Title:
PNEUMATIC TIRE
Document Type and Number:
WIPO Patent Application WO/2021/166792
Kind Code:
A1
Abstract:
Provided is a pneumatic tire that makes it possible to improve tire durability while ensuring the communication capability and durability of a transponder. A transponder 20 is embedded in the tire further outward than the carcass layer 4 in the tire width direction. The storage elastic modulus E'out(0°C) at 0°C and the storage elastic modulus E'out(-20°C) at -20°C of a rubber member with the largest storage elastic modulus at 20°C among the rubber members positioned further outward than the transponder 20 in the tire width direction satisfy the relationship 0.50 ≤ E'out(0°C)/E'out(-20°C) ≤ 0.95. The storage elastic modulus E'in(0°C) at 0°C and the storage elastic modulus E'in(-20°C) at -20°C of a rubber member with the largest storage elastic modulus at 20°C among the rubber members positioned further inward than the transponder 20 in the tire width direction satisfy the relationship 0.50 ≤ E'in(0°C)/E'in(-20°C) ≤ 0.95.
