A pneumatic caster is built with an air-filled (pneumatic) wheel, giving it the smooth, shock-absorbing rolling characteristic of a small vehicle tire — the caster-level equivalent of choosing a pneumatic wheel material.
Pneumatic casters are the go-to choice for rough, outdoor, or uneven terrain where a solid wheel would transmit every bump straight to the load.
Outdoor equipment, gravel, grass, and uneven or rough terrain.
Choosing pneumatic for smooth indoor floors expecting zero maintenance. A solid polyurethane or rubber wheel is usually simpler when the floor is already smooth and even.

Do pneumatic casters need maintenance?
Occasional reinflation, similar to any air-filled tire — foam-filled casters avoid this if that's a concern.
Are pneumatic casters good for indoor use?
They work fine indoors, but their real benefit shows on rough or outdoor terrain.
