Comparing Pneumatic to Airless Pivot Tires
Which is better for your center pivot irrigation system? A Pneumatic tire? or an airless/solid tire? To simply put, there are pros and cons to both.
Pneumatic Tires vs. Airless or Solid Pivot Tires
Pneumatic tires are the industry standard. The great thing about pneumatics is that they compress under pressure which helps with traction. They are easy on driving components and if they don’t go flat, they work amazingly. The problem with pneumatic tires is they go flat. A Flat tire out if the field can damage your irrigation system and costs money to replace them all the time.
A common solution for flat pivot tires is using airless tires. Airless tires like the name suggests won’t go flat, effectively making them no flat tires. There are many different materials these no flat tires are made over including solid steel, hollow plastic, polyethylene, and solid rubber. The largest issue with no flat tires is that they are very hard on your gearbox and driving components due to how stiff they are.
Top 5 Reasons To Use EWRS-PIVOT Airless Pivot Tires
When developing the EWRS-PIVOT irrigation tire we considered all this. We wanted to make a tire that had the benefits of the no flat solid tires and the compression of a pneumatic.
No Flats
The EWRS-PIVOT airless irrigation tire is a no flat tire. You will never have to replace flat tires in the field ever again.
Increased Traction
Even though the EWRS-PIVOT is an airless tire, it is designed to compress as a pneumatic would. It does this by using specific aggressive bidirectional tread along with core holes that will compress completely making the tire self-cleaning, which is a bonus.
Increased Flotation
Floatation is important for preventing deep rutting. The EWRS-PIVOT tackles this problem with its bi-directional tread design as well as its concave profile. the concave profile keeps mud under the tire unlike your traditional convex tire and the bi-directional tread won’t push material outwards. On top of that, the EWRS-PIVOT has a 14” width increasing its service area and therefore its floatation as well.
Serviceability
The EWRS-PIVOT is made with rubber segments that bold onto the rim. This means that you can easily replace any segment by using just a ¾” wrench.
Cost-Effective
Though traditional Pivot tires are cheaper upfront, the added expenses of replacing flats, fixing or replacing gearboxes, downtime expenses, and even potential crop yields make them expensive. The EWRS-PIVOT irrigation tires last 5+ years or 2-3 times longer than your traditional pneumatic and they are much more reliable. Saving you time, money, and headaches.
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.
