Abstract:
1. A non-directional pneumatic tire for supporting an agricultural irrigation system, comprising: first and second sidewalls and a radially outer wall defining an internal inflation chamber; a non-directional tread pattern defined on the tire and including a plurality of longitudinal protrusions positioned substantially parallel to a rotational axis of the tire; the longitudinal protrusions being arranged in a first row extending from the first sidewall toward and across an equatorial plane of the tire and a second row extending from the second sidewall toward and across the equatorial plane of the tire, the longitudinal protrusions of the first and second rows circumferentially alternating with each other and there being a circumferential spacing between adjacent longitudinal protrusions at the equatorial plane so that no portion of one longitudinal protrusion circumferentially coincides with another; each longitudinal protrusion of the first row including a contact surface, each of the contact surfaces of the first row increasing in circumferential width from the first sidewall toward the equatorial plane of the tire and then circumferentially eccentrically tapering to a rounded end; and each longitudinal protrusion of the second row including a contact surface, each of the contact surfaces of the second row increasing in circumferential width from the second sidewall toward the equatorial plane of the tire and then circumferentially eccentrically tapering to a rounded end.
