AR-PRO 4.80/4.00-8 Flat-Free Wheelbarrow Tires 2-Pack — 14.5" Solid Polyurethane, 3" Hub with Adapter Kit

These two AR-PRO 4.80/4.00-8 flat-free polyurethane tires with centered 3" hubs and an adapter kit give you reliable, maintenance-free wheelbarrow performance and fit most 13"–16" wheel assemblies.

Replace puncture-prone pneumatic wheelbarrow tires with a solid alternative built to resist sun, water, and wear. AR-PRO’s pair of 14.5-inch (diameter) x 3.2-inch (width) flat-free tires come mounted on metal rims and include extra bearings and nylon spacers so you can adapt the hub to different axle sizes. They’re designed to carry garden and jobsite loads without the hassle of inflating or repairing tubes.

Will these tires fit my wheelbarrow or garden cart?

These wheels target common small utility wheels: nominal 4.80/4.00-8 sizes and several similar measurements. The standard hub is centered, 3" long, and sized for a 5/8" axle; the included adapter parts let you use 3/4" axles too.

• Compatible with wheel diameters roughly 13"–16".
• Standard fit for 4.80/4.00-8, 4.00-8, 4.00-6, 3.50/2.50-8 tires.
• Ships with 5/8"-ready hub; swap bearings to fit 3/4" axles.
• Includes spacers to extend hub length when needed.

How do I change bearings or adapt the hub for a different axle?

Swapping bearings and adding the supplied nylon spacers is straightforward and requires basic hand tools. By replacing the 5/8" bearings with the included 3/4" bearings and using the nylon spacers, you can lengthen or widen the hub to match your axle diameter and clearance needs.

• Included: two 3/4" ball bearings per pack set (total 2 pieces for the pair).
• Includes two 1" nylon spacers and four 1/2" nylon spacers for hub length adjustment.
• Simple bearing press or mallet install; remove axle nut and slide old bearings out.
• Re-test wheel spin and axle clearance after installation.

What are the performance and durability features of these solid tires?

Made of solid polyurethane foam, these tires stay round and functional without air. They’re non-marking, resistant to rot and UV, and maintain their shape across seasons—so you won’t lose time patching or reinflating while working outdoors.

• Flat-free polyurethane foam construction; never needs airing.
• Non-marking tread suitable for driveways and patios.
• UV and water-resistant composition for long outdoor life.
• Rated up to 300 lb maximum load per entire wheel assembly.

How much weight can each wheel safely carry and on what terrains?

Each assembled wheel (polyurethane tire plus metal rim) supports up to 300 pounds when used within manufacturer recommendations. They handle typical yard and jobsite surfaces—gravel, dirt, mulch, and pavement—while providing consistent roll without flats.

• Maximum load capacity: 300 lb per tire assembly.
• Suitable for garden work, landscaping, hauling tools, and light construction materials.
• Good traction on mixed surfaces; not intended for high-speed or vehicle use.
• Perform reliably year-round, unaffected by punctures or pressure loss.

If you need a dependable, puncture-proof solution for hauling materials, trimming maintenance time, and avoiding roadside downtime, this 2-pack with adapter kit is designed to simplify fitment and deliver consistent service.
