Why Use An Airless Tire For Your Lindsay Irrigation System
Why should you go with an airless tire for your Lindsay irrigation system? The most common tire in the irrigation market is a pneumatic style tire however they oftentimes go flat long before their tread lifespan is up.
The solution to flat tires is going to airless tires which don’t use compressed air, so they don’t have the capability of going flat. However, there are a few drawbacks to airless pivot tires as well. Therefore, Evolution Wheel has come out with the EWRS-PIVOT series of irrigation tires. To provide a solution for everyone without causing another issue somewhere else.
Common issues with pneumatic pivot tires
- They go flat
- They cause ruts
- Inconsistent traction
They Go Flat
Pneumatic pivot tires, simply put, go flat. The harsh conditions that these tires must operate in cause rubber deterioration drastically reducing their life span. When these pivot tires go flat, they fill with mud and water weighing down your Lindsay pivot irrigation system and can pull your towers out of alignment, causing more damage.
When a tire does go flat, it is a massive headache. You need to go into the field take the tire off and replace it, then haul it off the field. This takes time, causes downtime, and can cause additional damage to the rest of the system. It ends up being extremely expensive when accounting for the repair costs, opportunity costs, and the cost of replacing all the damaged tires in a season.
They Develop Ruts
Rutting is also a common issue with pneumatic pivot tires. Rutting is caused when continuous travel occurs over the same track, creating a cavern. This causes soil and crop damage, additional damage to tires, and system stoppages due to getting stuck.
The source of the rutting is the tread design and convex profile of these tires. The tread design is designed to grab onto the ground to increased traction however it displaces the soil from underneath the tire digging itself into the ground. The convex profile refers to the rounded shape of the tire where the tallest point tapers off to the edges. This increases the risk of rutting as it pushes more soils from underneath the tire to the side.
Inconsistent Traction
Traction is also a common problem many farmers face when they have hills in their fields. When there is an incline your system must climb, and your pivot tires are flat or the tread is filled with mud, it can be hard to climb over. This causes additional stress on the driving components and causes additional damage to your system that is expensive to repair.
The EWRS-PIVOT Airless Pivot Tire
The EWRS-PIVOT airless center pivot irrigation tire was designed with all these problems in mind. It is engineered specifically to mimic a pneumatic pivot tires compression, a wide true to spec 14.9” x 24” profile to increase traction, and a concave profile that increases floatation which prevents rutting.
The EWRS-PIVOT is an airless tire which means that it will never go flat. Instead of compressed air, it has a unique core hole geometry that compresses completely when pressure is applied. This allows the tire to act 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. While 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.
The EWRS-PIVOT airless center pivot irrigation tire is engineered to solve the problems that farmers face when it comes to irrigation systems while not creating new ones. The unique design is a cost-effective problem-solving solution allowing you to trust your pivot 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.
