  • Pneumatic tire for travel on various kinds of grounds
    Patent number: 3951191
    Abstract: A pneumatic tire for travel on various kinds of grounds is disclosed. The tire comprises at least two different kinds of tread patterns distant apart from each other in the circumferential direction of the tire. One of these tread patterns has excellent slip resisting property when the tire is used on muddy ground and another tread pattern has high steering stability when the tire is used on hard ground. These two different kinds of tread patterns are mixedly present over any one half of the circumferential length of the tire. In addition, the amount of tread rubber per unit length which corresponds to at least one tenth of the circumferential length of the tire is substantially uniformly distributed along the overall circumferential length of the tire.
