Plastic Pivot Tires Vs. The EWRS-PIVOT Irrigation Tire

Plastic Pivot Tires

Let’s start with plastic pivot tires. Flat tires are the biggest problem farmers face when dealing with center pivot irrigation systems. Flat tires cause system stoppages that can damage the irrigation system itself, then changing the tire and getting it off the field is a massive headache.

The biggest appeal plastic pivot tires have is the fact they don’t go flat. Farmers that are incredibly frustrated with flat tires might see plastic tires as the solution for their problems. They’re no flat tires, low maintenance, and cheaper than other options. These are all great reasons for purchasing plastic pivot tires over traditional pneumatic pivot tires. The issue is they aren’t puncture-proof. Most plastic pivot tires are hollow and when punctured they fill with mud and water, weighing down the system and causing stoppages and increasing downtime. They also have no flexibility like a steel tire. This causes stress on the driving components leading to them needing to be replaced more often.

The EWRS-PIVOT Series Center Pivot Irrigation Tire

Like plastic pivot tires, the EWRS-PIVOT series irrigation tire will never go flat. It too is a low-maintenance tire, made to last and on top of that has the flexibility that steel tires do not.

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 and reducing stress on the gearbox increasing its lifespan as well. On top of that, the EWRS-PIVOT series tire is self-cleaning, so you don’t have to worry about added weight to the system.

The EWRS-PIVOT series is designed with a concave profile that keeps mud underneath the tire preventing ruts where the aggressive tread design 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. The rubber on our tires will last 2-3 times the life span of your traditional pneumatic tire, without the risk of going flat.

Ultimately, plastic pivot tires are a great solution to flat tires, but it still causes issues elsewhere. The EWRS-PIVOT series addresses the issues of flat tires and rutting in your field while not increasing stress to your gearbox.

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.
