Which vehicles and uses are these 4.10/3.50-4 wheels suited for?

These wheels work well on hand trucks, utility wagons, garden trailers and wheelbarrows where slow, steady loads are common. They are not intended for road-speed vehicles or heavy machinery like lawn mowers.

• Common fits: dollies, hand carts, garden wagons, wheelbarrows
• Not for highway or high-speed use
• Unsuitable for large lawn or industrial mowers

How does the flat-free PU tire perform compared with pneumatic tires?

The polyurethane (PU) construction resists punctures and abrasion, eliminating flats and reducing maintenance. The tread pattern improves traction on uneven ground while the rigid material keeps its shape under load.

• Puncture-resistant PU avoids tube repairs
• Patterned tread increases grip on garden paths and gravel
• Consistent pressure-free performance over time

What does the kit include and how do I adapt it to my axle?

Each wheel comes with multiple bearings and spacers so you can fit common axle diameters without buying extra components. The hub has a 5/8" bore plus included adapters for 3/4" and 1/2" bearings and assorted spacers for correct wheel offset.

• Included: 2 x 3/4" bearings and 2 x 1/2" bearings
• Includes 6 × 1/4" spacers, 2 hole spacers, and 1 retaining pin
• Offset hub length: 2.2"; axle bore adaptable

What load capacity and durability can I expect from these wheels?

• Steel rim for structural strength
• PU material resists abrasion and punctures
• Suitable for carrying typical garden and utility loads
