Airless Pivot Tires vs. Pneumatic Irrigation Tires Tread Pattern
What Is Bi-Directional Tread
Traditional pneumatic pivot tires have a chevron directional tread pattern that will push mud and materials out from underneath the tire. This digs into the ground and creates deep ruts. The EWRS-PIVOT airless irrigation tire is designed with a bi-directional tread design. The bi-directional tread has a symmetrical pattern that acts the same when the tire is facing the front and back while also not pushing material away from the tire.
Core Geometry
Being an airless tire, the EWRS-PIVOT uses a unique core geometry that allows the tire to compress instead of compressed air. The core holes on the EWRS-PIVOT series are wide and shallow which maximizes ground contact, increasing traction while also allowing the core holes to compress completely flat. When the tire’s core holes compress completely flat, it pushes any material within the tire out effectively making it a self-cleaning mechanism. This compression does two things, increases traction and is self-cleaning
By pairing this with a concave profile and bi-directional tread, the EWRS-PIVOT has increased both floatation and traction all while eliminating flat tires in your field.
The EWRS-PIVOT airless Center Pivot Irrigation Tire
The EWRS-PIVOT airless center pivot irrigation tire solves all these issues. It is engineered specifically to mimic a pneumatic irrigation tires compression, a wide true-to-spec 14.9” x 24” profile to increase traction and a concave profile that increases floatation while preventing rutting.
The EWRS-PIVOT has a unique core hole geometry that compresses completely when pressure is applied. This allows the tire to compress like a pneumatic mimicking its traction as well as being self-cleaning, so you don’t have to worry about added weight to the system.
The concaved true to spec 14.9” X 24” profile keeps mud underneath the tire, spreads the weight over an increased surface area, and the aggressive tire tread pattern increases overall floatation and traction.
The EWRS-PIVOT’s high-quality rubber has UV protection, and the rims are made with high-strength steel that will last a lifetime. It is also a segmented tire. Each segment is attached to the rim with ¾” nuts. This allows you to service the tire and easily replace a segment when it’s damaged. The rubber on our tires will last 2-3 times the life span of your traditional irrigation system, without the risk of going flat.
The EWRS-PIVOT airless irrigation tire is engineered to solve the problems that farmers face when it comes to irrigation systems while not creating new ones. The unique design is a cost-effective problem-solving solution allowing you to trust your irrigation tires not to fail on you.
EWRS-PIVOT SERIES
The EWRS-PIVOT series of airless pivot tires from Evolution Wheel offers the most advanced airless technology to the irrigation market. This solution delivers serviceability, traction, and floatation into one impressive offering.
Our tread design and tire profile offer greater traction through mud and obstacles. The unique concave contact face helps eliminate rutting by keeping dirt under the tire, where it belongs. The face of the tire is pointed inwards. Compared to typical pneumatic irrigation tires which convex shape push mud out from under the tire, causing ruts.
Our proprietary segmented design bolts onto our high strength wheel, allowing you the ability to service the tire quickly, eliminating the need to change a tire in the field.
Unlike other airless pivot tires, the EWRS-PIVOT compresses flat pushing material out, it's a self-cleaning system. The compressed cores elongate the footprint of the tire allowing it to wrap over obstacles increasing traction and reducing ground pressure.
