Abstract
【解決手段】一対のビード部1に配設されたビードコア1a間で延在し、そのビードコア1aの周りでタイヤ径方向外側に巻き上げられたカーカスプライ4と、ビードコア1aの周りで、タイヤ幅方向の内側から外側に亘ってカーカスプライ4を包み込むように配設されたチェーハー6とを備える空気入りラジアルタイヤにおいて、タイヤ幅方向内側に位置するチェーハー6の内側端6Eiが、カーカスプライ4の巻き上げ端4Eよりもタイヤ径方向外側に配され、タイヤ径方向外側に向かって先細りとなる補強ゴム10が、内側端6Eiのタイヤ径方向外側に隣接して設けられている。
【選択図】図2
Description
図1,2に示すタイヤ構造において、補強ゴム10を具備しない代わりに、チェーハー6の内側端6Eiにエッジテープ12を取り付けたこと以外は、実施例2と同じであるものを比較例1とした。
図1,2に示すタイヤ構造を備えるものを実施例1〜3とした。実施例1では、厚みT1を3mm、距離Xを30mm未満とし、実施例2,3では、厚みT1を3mm、距離Xを30mmとした。また、実施例1,2では、補強ゴム10のモジュラスを一律に4.2MPaとし、実施例3では、補強ゴム10における高モジュラス部分(図3で斜線を付した部分)のモジュラスを4.2MPa、残りの部分のモジュラスを3.6MPaとした。評価結果を表1に示す。
