Pneumatic 11.2 x38 Pivot Tire Vs. a 14.9 x 24 and The EWRS-PIVOT
Benefits of Tire Size
switching out tires is the first thing farmers do to prevent rutting. using either a taller 11.2" X 38" pivot tire or the wider 14.9" x 24" pivot tire. While the wider tires increase the surface area to help with floatation, the taller tires allow for more clearance for your system as the ruts get deeper.
Pneumatic vs. Airless
Pneumatic pivot tires have a rounded shape that digs into the ground to create traction. This pushes soil outwards and the combination of wet soil and continuous traffic over the same route causes rutting.
The EWRS-PIVOT irrigation tire is engineered with a concave profile as opposed to a convex profile. The concaved profile holds mud underneath the tire instead of pushing the mud to the side. The tire also features a bi-directional tread and wide true-to-spec 14.9" x 24". All these features work together to minimize the ruts in your field.
Why Go Airless?
In addition to the anti-rutting design, the EWRS-PIVOT is an airless tire. Eliminating flats in the field. The big problem with airless tires is that they have no flexibility. So we designed the EWRS-PIVOT with unique core geometry that allows the tire to compress as a pneumatic tire would. Compression in a tire helps with traction and because the core geometry compresses completely, it also creates a self-cleaning system.
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.
