79 Series Replacement Pneumatic Tire & Tube sets are made for customers who already have the caster/wheel and just need fresh rubber. These air-filled tires bring back the cushioned ride and traction you want on rough floors, gravel, cracks, thresholds, and shop debris—helping protect your load by reducing vibration. Perfect when your current tire is worn, dry-rotted, or keeps going flat. This listing is for the tire + inner tube only (no caster frame, no wheel/rim).
