Evolution Wheel spends a lot of time in the research and development stage for their products. To start, Evolution Wheel engineered the EWRS-HS series for severe duty applications where tire wear is the biggest concern. To do this they redesigned the tread pattern to maximize surface area.
The EWRS-HS doubled the surface area of the EWRS-AT Series to 66 percent to spread the weight of the machine out. This lowers the pressure per square inch on the concrete while extending its wear life significantly. Additionally, the EWRS-HS series has the deepest tread on the market, measuring at 52/32". The deeper the tread, the more it can wear, increasing longevity as well. These two features allow the tire to last three to five times the lifespan of a traditional pneumatic tire.
Solid tires have a reputation for being rough on machines and the operator driving them. Evolution Wheel wanted to reduce driver fatigue and make it easier for operators to perform their jobs.
To combat this, Evolution Wheel designed the EWRS-HS tire with specialized core geometry, referring to the apertures within the rubber. The specialized core geometry in these tires allows them to compress like a pneumatic tire without the bounce. The tread design also allows the machine to skid smoothly so the operator can push the machine harder and increase productivity.
Like all Evolution Wheels tires, the EWRS-HS is a segmented tire. This allows the operator to service the tire right on the job site with just a ¾” wrench, replacing the damaged segment within minutes.
