NING SHUO 4.10/3.50-4 Solid PU Tire & Wheel 4-Pack — 10 in x 3.2 in, 5/8 in Axle Bore, Double-Sealed Bearings

These are four solid, flat-free 4.10/3.50-4 polyurethane (PU) tires and wheels designed to replace inflatable wheels on dollies, wheelbarrows, dump carts and small garden equipment.

Built as a heavy-duty substitute for inner-tube tires, the NING SHUO 4.10/3.50-4 set combines a one-piece rim, double-sealed bearings and a solid PU foam tread to deliver puncture-proof operation and reliable load support. The wheels arrive with washers and cotter pins for straightforward installation and are specifically sized for equipment using a 5/8" axle bore and a 2.15" offset hub.

Will these wheels fit my wheelbarrow, cart, or dolly?

Check the hub and axle dimensions of your equipment before ordering. These wheels accept a 5/8" (0.625") axle and have a 2.15" offset hub, with an overall tire diameter of 10" and tire width of about 3.2".

• Compatible tire model: 4.10/3.50-4
• Tire diameter: 10" (approx.)
• Tire width: 3.2"
• Axle bore: 5/8"; hub offset: 2.15"

How durable and load-capable are these solid PU wheels?

The wheels use high-strength polyurethane foam and a one-piece rim with double-sided welding where the sleeve meets the hub, increasing impact resistance. Each wheel is engineered to support up to 240 lb under typical loads, offering better puncture resistance than pneumatic tires.

• Solid, airless PU construction resists punctures and tears
• Double sealed bearings for smoother rolling and protection from debris
• One-piece rim and reinforced hub welding for higher load tolerance
• Rated load per wheel: up to 240 lb (single tire)

What traction and terrain can I expect with these tires?

The tread pattern is designed for grip and slip resistance on common landscaping and yard surfaces, while the PU compound holds up to abrasion better than inexpensive rubber alternatives. They are best for firm ground, gravel, paved surfaces and packed soil where puncture risk is a concern.

• Anti-slip tread for improved traction on varied surfaces
• Wear-resistant compound for extended service life
• Suitable for equipment like yard wagons, generators, and snowblowers
• Not recommended for high-speed or highway use

How easy is installation and maintenance?

Installation is straightforward: slide the wheel onto a compatible 5/8" axle, secure with the included washers and cotter pins, and you’re ready. Maintenance is minimal since these are airless wheels—no pumping or patching—just occasional cleaning and bearing checks.

• Includes washers and cotter pins for quick mounting
• No inflation, patching, or inner tubes needed
• Inspect bearings and hub welds periodically for long-term reliability
• Wipe clean of debris to maintain rolling efficiency

Who is this for: These NING SHUO solid PU 4.10/3.50-4 wheels are ideal for homeowners, landscapers, and light-commercial users who want a low-maintenance, puncture-proof replacement for inflatable tires on wheelbarrows, garden carts, dump carts, dollies, portable generators, pressure washers and other small equipment. Choose this 4-pack when you need dependable, ready-to-install wheels that reduce downtime from flats and deliver consistent performance for transport and yard work.
