Benefits of different Pivot Tires - Size and Types

 

Benefits of Tire Size

The most common solution farmers use to prevent rutting is switching out their tires. Either for a taller 11.2” x 38” Irrigation tire or a wider 14.9” x 24” irrigation tire. A taller tire will provide more clearance for the gearbox allowing for deeper ruts, whereas wider tires increase the Tire’s surface area, increasing floatation and preventing deep ruts.

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 to hold soil underneath the tire to prevent rutting. It achieves this with a concave profile and bi-directional tread along with a wide footprint. 14.9”x 24” to be exact. The concave profile and bi-directional tread hold the soil underneath the tire and the wide footprint distributes the weight across the footprint, which minimizes the issue of deep rutting.

Why Go Airless?

Along with the anti-rutting design, the EWRS-PIVOT is an airless irrigation tire. Being an airless tire, there is no possibility of flat tires which takes time and money to fix. It also acts like a pneumatic where other airless tires do not. Airless tires are known for being stiff and hard on driving components, however, the EWRS-PIVOT tire is designed with core holes that compress when pressure is applied, mimicking a pneumatic tire. The cores are also self-cleaning, so you don’t have to worry about adding weight to the 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.
