Description
前記サイピングは、ブロック表面で開口する開口縁形状において、山谷を繰り返してジグザグ状にのびるジグザグ部を有し、かつサイピングの深さ方向においては、前記開口縁形状を実質的に保持しつつ、前記ジグザグ部がサイピングの長さ方向の一端側に変位するジグザグ変位部と、他端側に変位するジグザグ変位部とが交互に繰り返すとともに、
ブロック表面側のジグザグ変位部の前記長さ方向と直角方向の変位量をW1、サイピング底側のジグザグ変位部の前記長さ方向と直角方向の変位量をW3、及びその間に配される中間のジグザグ変位部の前記長さ方向と直角方向の変位量をW2としたとき、次式を充足することを特徴としている。
W1≧W2
0.7×W2≧W3>0

0.7×W2≧W3>0 −−−−(2)
L1≧L2 −−−−(3)
0.7×L2≧L3>0 −−−−(4)
試供タイヤに正規内圧を充填し、ブロック表面に0.0274kgf/mm2 の縦荷重を負荷した状態で、路面をタイヤ周方向に0mmから3.0mmまで変位させるとともに、そのときの反力を測定した。ブロック剛性は、3.0mm変位時の反力を変位(3.0mm)除した値とし、従来例を100とした指数で表示している。値が大なほど剛性が高い。
生のブロックにナイフブレードをセットして加硫し、その後ナイフブレードをブロック表面と垂直に引っ張り、ナイフブレードが抜けるまでの引っ張り力の最大値を、従来例を100とした指数で表示している。値が小なほど抵抗が低い。
