- トレッド中心線に沿う周溝(3)と、この周溝(3)の幅方向両側に接地輪(4)とを有し、前記周溝(3)の幅方向両側壁が、溝底ほど狭くなるテーパ面又は湾曲面をなし、
直進走行時は、前記両接地輪(4、4)が接地する一方で、カーブ走行時は、前記両接地輪(4)の一方の接地輪(4b)に重心移動するとともに、他方の接地輪(4c)が路面から離れて、そのカーブを行うようにし、
砂地やぬかるみ等のタイヤがめり込みやすい路面(G)を走行する際に、この路面(G)の砂等が前記テーパ面又は湾曲面によって前記周溝(3)内に誘導されるとともに集積され、この集積した砂等を支えとして前記路面(G)へのめり込みを防止するようになっており、
タイヤ周方向断面において、前記周溝(3)の最底部(3a)と、前記両接地輪(4、4)の外径最大部(4a)とを結ぶタイヤ外形が、前記最底部(3a)の両側にそれぞれ一つの変曲点(5)を有する一つの滑らかな曲線で描かれ、この曲線の前記最底部(3a)と両外径最大部(4a)における傾きが水平であり、
前記周溝(3)内に、その溝底から径方向外向きに起立して前記路面(G)をグリップするグリップ部(12)を設け、このグリップ部(12)よりも前記両最大外径部(4a、4a)の方が径方向外側に突出しているタイヤ。 - 前記グリップ部(12)の回転周方向の両側に、このグリップ部(12)の前記周方向幅を前記周溝(3)の溝底に向かうほど拡大するテーパ面又は湾曲面を形成した請求項1に記載のタイヤ。
- 中実構造のチューブレス式とした請求項1又は2に記載のタイヤ。
- 前記周溝(3)の横幅(W1)が、タイヤ全幅(W2)の20〜90%の範囲内である請求項1乃至3のいずれか一つに記載のタイヤ。
- 荷物運搬用の手押し車(2)に適用する請求項1乃至4のいずれか一つに記載のタイヤ。
