Title:
PNEUMATIC TIRE
Document Type and Number:
WIPO Patent Application WO/2022/185801
Kind Code:
A1
Abstract:
The present invention provides a pneumatic tire that can achieve, in a balanced manner, improved steering stability, noise performance, and water dispersal performance. An inner intermediate land section 12B has multiple inner intermediate lug grooves 13B. An outer intermediate land section 12D has multiple outer intermediate lug grooves 13D. The length L1 of the inner intermediate lug grooves 13B and the length L2 of the outer intermediate lug grooves 13D satisfy the relationship L1 > L2. The relationship of the distance W1 between the tire equator and an inner shoulder main groove 11A, the distance W2 between the tire equator and an inner center main groove 11B, the distance W3 between the tire equator and an outer center main groove 11C, and the distance W4 between the tire equator and an outer shoulder main groove 11D with respect to the distances Wi, Wo between the tire equator and grounding ends satisfy 0.58 ≤ W1/Wi ≤ 0.62, 0.20 ≤ W2/Wi ≤ 0.24, 0.15 ≤ W3/Wo ≤ 0.19, and 0.53 ≤ W4/Wo ≤ 0.57. The total value of the groove width WG1 of the inner shoulder main groove 11A and the groove width WG2 of the inner center main groove 11B is larger than the total value of the groove width WG3 of the outer center main groove 11C and the groove width WG4 of the outer shoulder main groove 11D.
