💡 Why are pneumatic caster wheels used for carts and equipment on rough surfaces?
Pneumatic casters are used when shock absorption and traction matter more than hard floor speed.

• Air filled rubber tires cushion loads and reduce vibration transfer

• Knobby tread improves control on uneven or outdoor surfaces

• Swivel and rigid combo helps with steering and straight tracking

• Lower rolling resistance makes heavy loads easier to push

These casters are a handy choice when you need stable movement, better grip, and smoother rolling for heavy equipment that travels across mixed indoor and outdoor surfaces.
