Title:
PNEUMATIC TIRE
Document Type and Number:
Japanese Patent JP2015051768
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a pneumatic tire which can maintain or improve steering stability while reducing rolling resistance.SOLUTION: A pneumatic tire 1 includes a pair of bead parts 2, side wall parts 3 respectively continued to the bead parts 2, and a tread part 10 connecting the side wall parts 3. A ratio of the total width SW of the pneumatic tire 1 to the outer diameter OD of the pneumatic tire 1 satisfies a relation of SW/OD≤0.3, and a ratio of the inner diameter RD of the pneumatic tire 1 to the outer diameter OD satisfies a relation of RD/OD≥0.7. When the length from one second reference point Q1 to the other second reference point Q2 along a tread profile 12 is designated as the tread development width TDW, a relation of 0.5≤TDW/SW≤0.7 is satisfied.
