Irrigation Pivot Tires Better Traction Without Sacrificing 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.
The EWRS-PIVOT series is an airless field sprinkler irrigation tire
The EWRS-PIVOT airless field sprinkler 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 pneumatic irrigation tire, without the risk of going flat.
The EWRS-PIVOT airless field sprinkler irrigation tire is engineered to solve the problems that farmers face when it comes to field sprinklers 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.
