MerryYard 4.80/4.00-8 Pneumatic Wheel Assembly — 4.80/4.00-8 Tire, 2PR Nylon, 3" or 6" Center Hub, 5/8" or 3/4" Bushing

MerryYard's 4.80/4.00-8" pneumatic wheel assembly is a heavy-duty, air-filled replacement wheel built for wheelbarrows, garden carts, trolleys and utility wagons.

This wheel assembly is designed as a direct replacement for many common utility wheels: a 15.3" tire diameter with a 3.87" tread width, 2-ply (2PR) construction and a choice of 5/8" or 3/4" powdered metal bushings. It ships with valve accessories so you can install or service the inner tube quickly. The tread pattern and nylon cord carcass aim to deliver better puncture resistance and ride comfort than lighter, economy tires.

Will this wheel fit my wheelbarrow or garden cart?

Compatibility depends on four key measurements: tire size (4.80/4.00-8"), hub type (center hub), hub length (3" standard, can be extended to 6") and bushing diameter (5/8" or 3/4"). If all four match your current wheel, this assembly should be a drop-in replacement.

• Confirm tire sidewall reads 4.80/4.00-8".
• Measure hub length: 3" or extended up to 6" required.
• Check inner bushing bore matches 5/8" or 3/4".
• Center-hub mounting must match your axle arrangement.

How durable and comfortable is this pneumatic wheel?

The wheel uses a heavier 3.3 lb tire body with a nylon cord construction that increases strength versus typical 2.45 lb polyester-cord tires. The air-filled (pneumatic) design provides shock absorption over rough ground, while the 2PR rating and deeper cross-pattern tread improve wear life and grip in garden settings.

• 2PR nylon cord carcass for added strength and puncture resistance.
• Cross-pattern tread for traction on soil, gravel and turf.
• Pneumatic cushioning for smoother pushing and rolling.
• Powdered metal bushing for long-lasting axle support.

What accessories come with the wheel and how do I maintain it?

The package includes a valve spanner, three valve cores and two valve caps so you can remove or replace the inner tube and service the valve without hunting tools. Routine maintenance is straightforward: keep the tire inflated to the recommended pressure, inspect for punctures, and ensure the bushing and hub are clean and lubricated.

• Valve spanner and spare valve cores included for easy servicing.
• Replace inner tube if punctured; use included valve cores during reinstallation.
• Wipe hub and bushing clean and add light grease as needed.
• Do not use for highway or continuous static loads beyond rated capacity.

How much weight can this wheel support and what are the limits?

The assembly is rated to handle dynamic loads up to approximately 300 lbs, making it suitable for typical garden and utility tasks. This rating is for rolling use (dynamic); it is not intended to bear long-term static loads or be used on highway vehicles.

• Rated dynamic load capacity: about 300 lbs.
• Designed for wheelbarrows, carts, trolleys, generators and similar equipment.
• Not suitable for permanent static loading or highway use.
• Check that hub and bushing dimensions match before ordering.

Who this is for: gardeners, landscapers and homeowners who need a dependable, air-filled replacement wheel for wheelbarrows, yard carts, light-duty generators and trolleys. It also suits rental shops, small farms and DIYers who prefer a ride-friendly pneumatic wheel with replaceable valve hardware and durable powdered metal bushings. If your current wheel's dimensions match the 4.80/4.00-8" size, center hub configuration and bushing diameter, this MerryYard assembly delivers an easy swap and improved rolling performance.
