Description
(1)本発明に係る空気入りタイヤのトレッド面に形成されるトレッドパターンは、前述の実施形態で示したものに限られず、パターンのピッチや陸部の形状も特に限定されるものではない。更に、底上げ部が形成される副溝の幅寸法や長さ、断面形状は特に限定されるものではない。
底上げ部11が接地可能な程度にまでトレッド面を摩耗させたテストタイヤを、実車(2000cc四駆車、2名乗車)に装着し、走行時のノイズを乗員2名により官能評価した。なお、タイヤの空気圧は210kPaとし、走行速度40〜100km/hにおけるノイズを評価した。比較例を100として指数評価し、数値が大きいほどノイズが小さい、即ち異音レベルの抑制効果が大きいことを示す。
底上げ部11が接地可能な程度にまでトレッド面を摩耗させたテストタイヤを、実車(2000cc四駆車、2名乗車)に装着し、濡れた路面を走行中にハンドルを切ったときの応答性をドライバーが官能評価した。なお、タイヤの空気圧は210kPaとした。比較例を100として指数評価し、当該数値が高いほど応答性が良い、すなわちWET性能に優れていることを示す。
トレッド面に図2、3に示すパターンが形成されたテストタイヤ(サイズ225/70R16)を作製した。但し、副溝13aに底上げ部11を形成しつつ、底上げ部12を設けない構成とした。なお、副溝13aは幅2mmとし、底上げ部11は長さ3mm、高さDを5mmとした。また、底上げ部11間距離Lは29mmとした。
副溝13aに底上げ部11を形成しつつ、底上げ部11間に1つの底上げ部12を形成した点以外は、比較例と同じとした。なお、底上げ部12は長さ2mmとし、高さdおよび距離L1、L2を表1で示す寸法にした。

Claims (3)
- 複数の溝部と、その溝部によって区分された複数の陸部とが、トレッド面に形成された空気入りタイヤにおいて、
前記溝部は、タイヤ周方向に沿って延びる周方向溝とタイヤ周方向に交差して延びる傾斜溝とを含む主溝と、その傾斜溝よりも浅く、前記傾斜溝に連通してタイヤ周方向に延びる副溝と、前記副溝の前記陸部を区分する部分の両端付近に形成された一対の第1底上げ部と、その第1底上げ部間に形成された少なくとも1つの第2底上げ部と、を備えることを特徴とする空気入りタイヤ。 - 前記第1底上げ部間に前記第2底上げ部が1つ形成されるとともに、前記第1底上げ部間距離をL、前記第2底上げ部の中央部から一方の前記第1底上げ部までの距離をL1とするとき、L1/Lが0.2〜0.8である請求項1記載の空気入りタイヤ。
- 前記第1底上げ部の一方から、その第1底上げ部に対向する前記第2底上げ部の中央部までの距離と、
その第2底上げ部の中央部から、その第2底上げ部に対向する前記第1底上げ部の他方、又は、その第2底上げ部に対向する前記第2底上げ部の中央部までの距離と、を異ならせた請求項1記載の空気入りタイヤ。
