A manufacturer of deep-tread plastic tires for center-pivot irrigation systems, RhinoGator, has expanded its product offering to include tires with shallow treads. The shallow tread is intended to reduce soil disturbance, compaction and slippage specifically in light soils. They fit standard pivot wheels and can be premounted, if needed. Both deep- and shallow-tread tires come in 11.2-38 and 11.2-24 sizes from RhinoGator, based in Gothenburg, Neb. The tires are composed of composite polyeth-ylene resins and corn-based plastic; they feature a non-directional tread design. The tires come with the highest available ultraviolet protection package and are covered by a five-year limited warranty. For more information, visit www.rhinogator.com.
