What Does Semi Pneumatic Mean?

Semi-pneumatic tires are inflated tires that are also constructed with a sturdy exterior similar to that of solid tires. Unlike the pneumatic tires that are used on other vehicles, semi-pneumatic tires are not pressurized. The air in the tire is simply trapped in the hollow cavity within the tire design.

Do pneumatic tires go flat?

They can withstand punctures and debris, and still operate well. Pneumatic tires, on the other hand, risk failure due to punctures and debris. And even without damage that may cause a flat tire, they must still be checked and refilled with air regularly to keep them inflated properly.

What are semi-pneumatic casters?

Semi-pneumatic caster wheels feature an extra thick, solid soft rubber tire on an industrial plastic center and are ideal for uneven floors indoors or on grass outdoors, but should not be used on sand or gravel surfaces.
