AR-PRO 4.80/4.00-8 16" Flat-Free Solid Wheelbarrow Tires 2-Pack — 3" Hub, 5/8" & 3/4" Adapter Kit, Polyurethane Foam

These AR-PRO 4.80/4.00-8" flat-free solid tires are 16-inch polyurethane-foam wheelbarrow replacements that include a 3" centered hub and an adapter kit to fit 5/8" or 3/4" axles.

Replace puncture-prone pneumatic wheels with a maintenance-free pair designed for garden carts, wheelbarrows, hand trucks, and light equipment. Constructed from molded polyurethane foam, each tire combines the stability of a solid wheel with cushioning that approximates air-filled rubber. The package ships as a 2-pack of complete tire-and-wheel assemblies plus extra bearings and nylon spacers so you can adapt the hub length and axle fitment quickly.

How do these solid polyurethane tires perform compared to air tires?

Polyurethane foam is resilient and keeps its shape under load, eliminating flats while still delivering a forgiving ride over rough ground. These tires resist cracking, weathering, and water damage that shorten the life of some rubber tires. They are non-marking and designed for repeated outdoor use without rotting.

• Flat-free construction removes risk of punctures and blowouts.
• Polyurethane formula resists sun, rain, and salt exposure.
• Comfort-oriented density gives smoother rolling than hard-solid wheels.

Will these wheels fit my wheelbarrow or cart?

Each wheel assembly has a 3" centered hub built to accept a 5/8" axle with 5/8" bearings installed. The included adapter kit makes it simple to convert the bearing fit to 3/4" axles and extend hub length for different frames. They are compatible with many common replacement sizes ranging from about 13" to 16" overall diameter.

• Stock fit: 3" centered hub with 5/8" bearings for standard axles.
• Includes two 3/4" ball bearings to swap in for larger axles.
• Nylon spacers (1" and 1/2") let you lengthen the hub to suit wider frames.
• Replacement size equivalence: fits multiple 4.80/4.00-8 and similar tires.

How much weight can each tire carry and what surfaces suit them?

Each assembly supports up to 440 pounds maximum when installed per instructions and used on typical garden or utility machinery. The tread and foam construction handle dirt, gravel, paved driveways, and yard terrain without flattening or tearing. For best longevity, avoid continuous, heavy industrial use beyond rated loads.

• Load rating: up to 440 lbs per tire for normal utility use.
• Good traction on loose soil, lawn, and compacted gravel.
• Non-marking tread suitable for patios and finished driveways.

What do I get in the box and how easy is installation?

The two-wheel pack contains two complete 16" polyurethane tires pre-mounted to metal rims, plus an adapter kit of bearings and spacers. Installation is straightforward: remove old wheel, fit the new hub onto your axle, and swap bearings or add spacers if needed. No special tools are usually required beyond standard wrenches and a hammer or press to seat bearings if they’re tight.

• Contents: two 4.80/4.00-8" solid tires on rims.
• Adapter kit: two 3/4" ball bearings, two 1" nylon spacers, four 1/2" nylon spacers.
• Typical installation: wheel off, bearing swap or spacer placement, wheel on.

Choose this 2-pack when you need reliable, weather-resistant replacements that reduce maintenance, prevent downtime from flats, and fit a variety of axle setups using the included adapter parts.
