Pneumatic Rubber Wheels

Pneumatic wheels excel on outdoor and rough surfaces: gravel paths, cracked pavement, grass, dirt, construction sites, loading docks with lip transitions, and any surface with significant irregularity. They are commonly used on garden carts, nursery wagons, platform trucks used outdoors, construction equipment dollies, and boat launch trailers.

Most pneumatic caster wheels operate at 20 to 50 PSI, depending on the tire size and load. The correct pressure is typically printed on the tire sidewall. Under-inflation causes excessive tire flex, increased rolling resistance, and premature wear. Over-inflation reduces the shock absorption benefit and can cause a harsh ride. Check pressure monthly for best performance.

Yes. Like any air-filled tire, pneumatic wheels can go flat from punctures, valve failures, or slow leaks. This is their primary drawback. For applications where a flat tire would cause significant downtime or safety concerns, consider semi-pneumatic wheels, which offer a similar profile and moderate shock absorption without the risk of flats.

Pneumatic rubber replacement wheels typically support 200 to 600 pounds per wheel, depending on tire size and construction. They are designed for light to medium-duty applications. For heavier loads on rough terrain, larger diameter pneumatic wheels or dual-wheel configurations may be required.
