Title:
空気入りタイヤ
Document Type and Number:
Japanese Patent JP6790841
Kind Code:
B2
Abstract:
The invention provides an inflating tire which suppresses tire shoulder wearing and improves offset driving performance. A tire shoulder land part (13) is provided with a tire shoulder cutting trough(20) of which width Wa is 18-28% of a circumferential distance Pa. A tire surface contour is provided with a second arc part (J2) with is intersected with a first arc part (J1) with a curvature radiusR1. Furthermore the curvature radius R2 of the second arc (J2) IS 5-15% of the curvature radius R1. A distance LQ between a tire equatorial plane (Co) and an intersection (Q) is 75-85% of a groundinghalf width Tw. A tire radial distance L2 between a tire equatorial point (Cp) and the intersection (Q) is 1-3% of the grounding half width Tw. A tire radial distance L1 between the tire equatorial point (Cp) and the tire surface grounding end (TE) is 4-6% of the grounding half width Tw.
