MerryYard 2-Pack Flat-Free Utility Wheels 4.10/3.50-6, 13in Steel Rim — 3in Centered Hub, 5/8in Bearings

MerryYard 2-pack 4.10/3.50-6 flat-free polyurethane utility wheels are replacement-ready 13" tires with steel rims and a 3" centered hub fitted with 5/8" ball bearings for hand trucks, dollies, and garden equipment.

If you need durable, maintenance-light wheels for frequent hauling, these MerryYard flat-free wheels provide a solid, puncture-proof alternative to pneumatic tires. Built with high-density polyurethane foam bonded to a powder-coated steel rim, each wheel has a 12.3" outer diameter, a 3.85" tread width, and a sealed hub assembly designed to accept a 5/8" bearing. Rated for about 300 lbs per wheel under typical dynamic use, the pair covers a wide range of compact utility machines and garden gear.

Will these wheels fit my hand truck or wheelbarrow?

Measure the current tire diameter, tread width, and hub details before ordering. These MerryYard wheels are designed as universal 4.10/3.50-6 replacements with a centered 3" hub and 5/8" ball-bearing interface, commonly used on 13" utility wheels.

• Outer diameter: 12.3" (commonly listed as 13" assemblies)
• Tread width: 3.85"
• Hub length: 3" centered; bearing bore: 5/8"
• Check internal bushing or axle sleeve dimensions for a correct fit

How tough are these flat-free polyurethane tires in everyday use?

The high-density polyurethane core resists punctures, cushions shocks, and minimizes bounce compared with solid rubber. They won’t lose air or require inflation, which reduces downtime and maintenance for jobsite and yard equipment.

• Material: PU foam for impact resistance and elasticity
• Tread: sawtooth pattern for traction on mixed surfaces
• Floor-friendly: leaves no black scuff marks on indoor floors
• Noise reduction: quieter rolling than many solid alternatives

What load and usage limits should I expect?

Each wheel is engineered for approximately 300 lbs of dynamic load; this makes the set suitable for two-wheel carts, hand trucks, and light utility trailers under typical moving conditions. They are not intended as long-term static support where weight sits stationary for prolonged periods, nor are they for highway or vehicle use.

• Single-wheel dynamic load rating: ~300 lbs (136 kg)
• Not recommended for continuous static loads or motor vehicle applications
• Ideal for yard equipment, generators, compressors, and trolleys

How easy is installation and what maintenance is required?

Installation is straightforward when you confirm hub and axle compatibility; the wheels come with a grease fitting to keep the bearing area lubricated and extend service life. No inflation, patching, or tube changes are necessary, saving time and reducing overall upkeep.

• Simple bolt-on replacement for compatible hubs with 5/8" bearings
• Includes grease fitting for periodic lubrication
• No air pressure checks or puncture repairs ever
