Abstract
Description
実施形態に係る空気入りタイヤ1の構成について、図面を参照しながら説明する。図1及び図2は、第1実施形態に係る空気入りタイヤ1のトレッドパターンを説明する展開図である。空気入りタイヤ1は、ビード部、カーカス層、ベルト層、トレッド部(以上、不図示)を備える一般的なラジアルタイヤ(スタッドレスタイヤ)である。空気入りタイヤ1は、車体の前進時の回転方向(R方向)が指定されている。
空気入りタイヤ1では、第1傾斜溝101と第2傾斜溝102とが回転方向前方側Fから回転方向後方側Bに行くに連れてタイヤ幅方向外側に向けて延びるように形成されている。このため、路面の水をタイヤ幅方向外側へ向けて排水する効果が高められる。
