空気入りタイヤ

Abstract

PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of exerting excellent drive performance on both road surfaces of pavement and irregular road while securing favorable drainage performance.SOLUTION: A pneumatic tire comprises a tread part 1 extending in a tire circumferential direction to form an annular shape; a pair of sidewall parts 2 disposed at both sides of the tread part 1; and a pair of bead parts 3 disposed inside the sidewall parts 2 in a tire radial direction. At least one circumferential groove 11 displacing periodically in a tire width direction while extending continuously along the tire circumferential direction is provided on the tread part 1. Besides, plural lug grooves 12 which extend in the tire width direction and whose both ends are closed are sprinkled on both sides of the circumferential groove 11 of the tread part 1 along the tire circumferential direction.SELECTED DRAWING: Figure 2
【課題】 良好な排水性能を確保しつつ、舗装路と不整路の両方の路面において優れた駆動性能を発揮することを可能にした空気入りタイヤを提供する。 【解決手段】 タイヤ周方向に延在して環状をなすトレッド部1と、該トレッド部1の両側に配置された一対のサイドウォール部2と、これらサイドウォール部2のタイヤ径方向内側に配置された一対のビード部3とを備えた空気入りタイヤにおいて、トレッド部1にタイヤ周方向に沿って連続的に延在しつつ周期的にタイヤ幅方向に変位する少なくとも1本の周方向溝11を設けると共に、トレッド部1にタイヤ幅方向に延在して両端が閉止された複数本のラグ溝12を周方向溝11の両側にタイヤ周方向に沿って点在させる。 【選択図】 図2
