Airless Irrigation Pivot Tire Increased Traction and Floatation

A common trope that we see is that you can’t have traction while also having floatation. We want to let you know that you can have your cake and eat it too.

Bi-Directional Tread

The tread on your tires is extremely important for traction. Using pivot tires with directional all-terrain chevron tread causes rutting and can hold onto mud adding weight to the tire bogging down the system.

The EWRS-PIVOT irrigation tire is designed with aggressive bi-directional tread meaning it doesn’t push material out to the sides, digging a track. Bi-directional tread doesn’t have angled lugs, instead, they are straight across the tire to provide traction without digging.

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.

Floatation

The concave profile is where floatation comes in. Unlike your traditional premium pneumatic tire, the EWRS-PIVOT series has a concave profile instead of a convex one. A concave profile refers to the shape of the tire where the diameter in the center is smaller than the diameter of the edges of the tire. This holds material underneath the tire when traveling over dirt where a convex tire will push material outwards.

On top of that, the EWRS-PIVOT series is true to spec tire meaning that the 14.9” x 24” dimensions are made to fit those specs exactly. Oftentimes manufacturers won’t build their tires to the specs that they advertise, negatively affecting floatation. Since the EWRS-PIVOT is a true-to-spec tire, the ground contact area is truly 14.9” wide, it spreads the weight of the system over a wider surface area increasing floatation.

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.
