PNEUMATIC TIRE
Document Type and Number:
Japanese Patent JP2015006871
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a pneumatic tire in which rolling resistance is reduced while holding reduction of steering stability performance to the minimum.SOLUTION: A pneumatic tire 1 includes: a pair of bead parts A; a pair of side wall parts B continuing to the bead parts; and a tread part D continuing to the side wall parts. When a total width thereof is denoted by SW and an outside diameter thereof is denoted by OD, the pneumatic tire satisfies "SW/OD≤0.3", and when a length along a tread profile to the other second reference point Q2 from one second reference point Q1 is defined as a tread development width TDW, satisfies "0.5≤TDW/SW≤0.7". A belt layer 20 includes: a low angle belt layer 20A including a cord extending at an angle of 0 degrees or greater and 10 degrees or less relative to the tire circumferential direction; and a high angle belt layer 20B including a cord extending at an angle of 20 degrees or greater and 70 degrees or less relative to the tire circumferential direction.
