Abstract
Description
本実施形態は、上記のように構成されており、以下その作用について説明する。図1,図2において、本実施形態に係る空気入りタイヤ10では、外層36がトレッド18の最外層であるので、未使用時から該外層36が接地面に露出した状態となっている。トレッド18の摩耗過程において、界面40に達するまで外層36の摩耗が進むと、内層38が露出し始める。このとき、接地面に外層36と内層38が混在した摩耗状態となる。内層38の摩耗進展は外層36よりも速いので、内層38が露出し始めるとトレッド18の摩耗進展速度が上がる。
界面40がタイヤ軸方向に平坦であるものとしたが、これに限られず、起伏が存在していてもよい。また、内層38は、外層26よりも摩耗進展が速いものとしたが、摩耗進展の速さの関係はこれに限られない。
Claims (5)
- トレッドを構成する外層と、
前記外層のタイヤ径方向内側に重なって前記トレッドを構成し、前記外層とは異なる摩耗特性を有する内層と、
前記外層と前記内層との境界を構成し、タイヤ軸方向から見たタイヤ径方向断面において、タイヤ径方向に振幅を有する波形状とされた界面と、
を有する空気入りタイヤ。 - 前記界面は、タイヤ軸方向には平坦である請求項1に記載の空気入りタイヤ。
- 前記内層は、前記外層よりも摩耗進展が速い請求項1又は請求項2に記載の空気入りタイヤ。
- 前記トレッドには、タイヤ周方向に延びる複数の周方向溝が形成され、
前記界面は、前記周方向溝の溝底よりもタイヤ径方向外側に位置している請求項1〜請求項3の何れか1項に記載の空気入りタイヤ。 - タイヤ回転方向が指定され、
タイヤ軸方向から見たタイヤ周方向断面において、前記界面が、タイヤ回転方向前方側に位置する前辺とタイヤ回転方向後方側に位置する後辺とがタイヤ径方向外側の頂点で交わる三角波形状を有し、前記前辺の長さが、前記後辺の長さよりも長く形成されている請求項1〜請求項4の何れか1項に記載の空気入りタイヤ。
