AR-PRO 16" Solid Polyurethane Wheelbarrow Tire 4.80/4.00-8 — 3" Center Hub, Flat-Free with Bearing Adapter Kit

AR-PRO's 4.80/4.00-8 flat-free wheel combines a 16-inch solid polyurethane tire, a 3" centered hub, and a bearing adapter kit so you get a maintenance-free replacement that fits 5/8" or 3/4" axles.

Whether you replace a worn wheelbarrow tire or upgrade garden carts, this solid polyurethane tire delivers the traction and shock absorption of a pneumatic with none of the puncture worries. Built to resist UV, water, and rot, the non-marking tire keeps rolling through season-to-season use. The package includes extra bearings and nylon spacers so you can adapt the hub length and bore size to common axle setups.

Will this tire fit my wheelbarrow or garden cart?

Yes — the 16" diameter and 3.2" tread width make this tire compatible with many popular small equipment sizes. It directly replaces sizes from 13" to 16" diameter, including 4.80/4.00-8, 4.00-8, 4.00-6, and 3.50/2.50-8 models. If your axle is 5/8" you can install it right away; if you have a 3/4" axle, use the included bearings and spacers.

• Fits nominal tire sizes: 4.80/4.00-8, 4.00-8, 4.00-6, 3.50/2.50-8
• Hub length: 3" centered; extendable with spacers to 6"
• Includes 3/4" ball bearings and nylon spacers for axle conversion
• Designed for both 5/8" and 3/4" axle applications

How durable and maintenance-free is the solid polyurethane tire?

Solid polyurethane foam reproduces the cushioning of air-filled tires while eliminating flats and inner-tube repairs. The compound resists sun, rain and chemical exposure so it won't rot, crack, or leave marks on delicate surfaces. You get a long service life in landscaping, construction, and general utility use.

• Flat-free solid polyurethane construction—no tubes to puncture
• Non-marking tread preserves floors and pathways
• Weather- and UV-resistant for outdoor storage and use
• Stable ride comparable to pneumatic tires without pressure checks

What load and terrain can these tires handle?

Each assembled wheel can carry up to 440 pounds, making it suitable for heavy loads on wheelbarrows, hand trucks, and utility carts. The tread and solid core perform reliably on dirt, gravel, pavement, and lawn surfaces, while the sealed bearing setup reduces downtime from maintenance. Avoid extreme off-road conditions that exceed the rated load.

• Maximum load capacity: 440 lbs per tire (entire assembly)
• Good traction on soil, mulch, pavement, and compact gravel
• Sealed bearings minimize service and keep rotation smooth
• Best for routine landscaping, garden and light construction use

Who is this wheel best for? DIY homeowners, landscapers, rental fleets, and light-construction crews who want a dependable, maintenance-light wheel will benefit most. It's ideal when you need a quick replacement that reduces downtime and eliminates flats while still offering cushioning similar to an air tire. The included adapter kit also makes it a flexible option for different axle sizes in mixed-equipment environments.
