Semi-Pneumatic, Skid Steer tire Apertures for Demolition

Common Aperture Patterns on Skid Steer Tires

The most basic aperture design is a single-row, round hole aperture pattern. These are used to reduce rubber costs however over time the sidewall cracks from the stress of heavy loads. The next style of apertures is a single row, elongated round aperture shape. An upgraded version of the round hole pattern, these tires won’t develop sidewall cracks, however, are very stiff to ride increasing driver fatigue. The third design is a staggered, round hole aperture pattern. This style of apertures provides a more comfortable ride compared to the others though they still don’t compare to a pneumatic tire.

The EWRS-AT and EWRS-HS Aperture Pattern 

Flexibility in a tire is important for traction. Though an inflexible solid tire can’t go flat it will slip on obstacles creating a rougher ride with less traction. With the addition of specially designed apertures in the rubber, the tire will be able to wrap around obstacles, grabbing them instead of slipping for both traction and comfortability. The core geometry in both the EWRS-AT and EWRS-HS tires are designed to flex like a pneumatic tire without the sway of a pneumatic tire. This creates a smoother, more stable ride for the operator, especially when carrying loads.

This is important in a demolition setting because of all the debris involved. To be able to drive over these obstacles without causing damage to the tire is important to lower your cost/hr and increase your ROI.

On top of that, both these tires are serviceable with only a 3/4" wrench. The rubber is bolted onto the rim in segments that are easily replaceable when needed. Limiting downtime from damaged tires to only a few minutes.
