Harper 16" x 4" Pneumatic Wheel - 435 lb Capacity

Each wheel supports up to 435 lbs. The 16-inch diameter and 4-inch width distribute the load over a large contact patch. The pneumatic air-filled design handles rough surfaces, curbs, and debris that would damage smaller solid wheels. Ideal for heavy dual cylinder carts and construction site use.

Pneumatic wheels provide better shock absorption on rough surfaces like gravel, dirt, and broken concrete common on construction sites. The air-filled tire cushions the load over uneven terrain where semi-pneumatic wheels would transmit every bump. Trade-off is occasional air pressure checks and puncture risk.

This wheel has a 4-1/4 inch hub width with a 3/4-inch ball bearing bore. The wider hub provides more lateral stability than standard 3-inch hubs, which matters on heavy loads where side forces during turns could cause the wheel to wobble. Verify your axle diameter matches 3/4 inch before ordering.

Check air pressure monthly and before heavy use. Inspect the tire for cuts, embedded debris, and sidewall cracks. Keep a patch kit or spare tube on hand for field repairs. The 3/4-inch ball bearing is sealed and needs no lubrication. Replace the tire when the tread is worn below the wear indicators.

The Harper 16" x 4" Pneumatic Wheel with 435 lb capacity is priced at $256.13 (SKU HRPWH72). Ships in stock from Creative Coating Solutions. Includes air-filled pneumatic tire, sealed 3/4-inch ball bearing, and 4-1/4 inch hub for WH series cylinder trucks.
