Abstract

PURPOSE:To increase resistance against wear by selecting properly a length of pitch of a zigzag for a rib with a tread pattern, an angle of deflection for the zigzag and an opening angle of main channels, without decreasing a grip efficiency. CONSTITUTION:As regards a zigzag pitch P, smaller is better against biased wear while the pitch of 0.7-0.12% of circumference of a tire is adequate for not decreasing a grip efficiency. It is proper to determine an angle of deflection and an opening angle within an extent of 16-27 deg. and 19-35 deg. espectively thereby preventing decrease of the grip efficiency and stone-bite and giving a good resistivity against wear.
