Watch: Hidden Cost of Solid Aperture Tires
“Solid Shock” refers to the impact of G-Force vibration emitted to heavy industrial vehicle operators and their equipment from solid aperture tires. Not only is Solid Shock a major source of wear and tear on machines, but it’s also a leading cause of operator injury. One example is Whole Body Vibration (WBV), which can cause fatigue, back pain, and spinal damage, which can lead to increased worker compensation claims. In contrast, polyurethane filled tires are designed for operator safety because they transfer the lowest G-force vibration of all flatproofing systems.
A significant indication of the cushioning ability of any tire lies in the durometer, or hardness of the rubber compound and other components. A solid tire with high durometer components is harder and absorbs less impact. A tire with low durometer components, such as polyurethane tire fill, is softer and absorbs more impact.
Polyurethane filled tires absorb more g-force vibration to reduce driver fatigue and decrease equipment stress. Heavy duty equipment operators seek as smooth a ride as possible.
Polyurethane-filled pneumatic tires offer a wider range of core durometers from 8 to 55, allowing heavy equipment operators to customize the deflection of the tire for the application.
Another stability factor to be considered is the density of a tire. Filling a pneumatic tire with polyurethane adds less weight to equipment than rubber, yet maintains stability.
From the perspective of the driver’s seat, TyrFil® polyurethane fill also provides better rough terrain traction and tire deflection (i.e. optimal tire contact area), which can reduce worker attrition and job absence due to a physiological effect called Whole Body Vibration or WBV. The impact of WBV may cause measurable muscular-skeletal and neurological injury to equipment operators. Aside from potential bodily harm to workers, WBV also costs companies utilizing heavy equipment thousands, if not millions of dollars, in lost work time due to driver absence during recovery, along with potential workers’ compensation and liability suits.

Whole Body Vibration (WBV), especially when it becomes a chronic condition, is suspected to cause adverse health effects such as fatigue, lower back pain, vision problems, interference with or irritation to the lungs, abdomen, or bladder, and adverse effects to the digestive, and urinary systems. Other issues include:
