Types of Center Pivot Irrigation Tires Vs. the EWRS-PIVOT Series
Whether you prefer traditional pneumatic irrigation pivot tires, steel pivot tires, plastic pivot tires, or rubber pivot tires they all have unique pros and cons. We looked at all the pivot tires on the market and have created a tire that we know blows them all out of the water.
Pneumatic Pivot Tires
Pneumatic pivot tires are by far the industry standard, however, they too have their pros and cons. The best features a pneumatic has are the compression and flexibility it offers. They will flex around obstacles providing traction and are made to be easy on the gearbox. The issue is, they go flat and they can create ruts.
When a pneumatic goes flat, either from sidewall damage or punctures, they fill with mud and water weighing down the tire and damaging the gearbox or the irrigation system itself. They also are prone to digging ruts because of the convex design of the tire as well as the directional tread. Ruts can cause soil and crop damage that will affect crop yields down the line.
Steel Pivot Tires
Steel tires will never go flat. Obviously. When you are frustrated with your pivot tires going flat out in the field, it may seem like a great idea to go for a steel tire. You would be right that a steel tire will never go flat however they have absolutely no flex, stressing the gearbox and you likely will have to replace them regularly.
Plastic Pivot Tires
Like steel tires, plastic irrigation tires won’t go flat. However, they are not puncture-proof. If a plastic pivot tire gets punctured, it will fill with water and mud increasing the weight of the tire and risks damaging the gearbox like the steel tire. On top of this, plastic pivot tires have very low flexibility causing poor traction and can damage the gearbox as well.
Rubber Pivot Tires
Airless rubber tires are better than steel and plastic tires when it comes to flexibility and traction. They can flex around obstacles making them easier on the gearbox.
The issue with rubber tires is that they still create ruts in the ground. Due to the shape of most airless rubber tires, they dig into the ground to increase their traction but in doing so digs tracts. Over time, this digging causes soil and crop damage and can also cause the tires to get stuck increasing the risk of damage on your center pivot irrigation system.
The EWRS-PIVOT Series Center Pivot Irrigation Tire
The EWRS-PIVOT irrigation tire takes all the pros of a pneumatic center pivot tire and other no flat pivot tires and minimizes the cons. They have similar flexibility and traction to a pneumatic, they are no-flat tires like the other airless tires and are anti-rutting as well. The EWRS-PIVOT is designed with a concave profile and an aggressive bi-directional deep tread design.
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 concave profile keeps mud underneath the tire where 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 bolted onto the rim so all you need is a 3/4" socket to service the tire when it’s damaged. That being said, the rubber on our tires will last 2-3 times the life span of your traditional center pivot irrigation system, without the risk of going flat.
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.
