The KGOJOY 13x4.00-6 solid tire is a flat-free, heavy-duty polyurethane replacement wheel designed for wheelbarrows, garden carts, trolleys, and other small utility equipment, complete with a centered hub and a multi-size bearing adapter kit for simple installation.

If you move soil, mulch, firewood or supplies regularly, a reliable tire that won’t go flat and that fits a variety of axles matters. This 13" x 4.00-6 solid tire combines a durable polyurethane tread, a thickened steel rim, and a pre-assembled centered hub with 5/8" bearings. An included adapter kit gives you 3/4" bearings, spacers, washers and cotter pins so the wheel can be adjusted to match common axle sizes and widths without extra parts.

How easy is this tire to install on my wheelbarrow or cart?

Installation is designed to be straightforward: the wheel ships with a 1.77" centered hub and 5/8" bearings already fitted. If your axle requires a larger bore, swap in the supplied 3/4" bearings and use spacers to set correct hub length. No special tools are required beyond basic wrenches and pliers.

• Pre-assembled hub with 5/8" bearings for immediate fit on common axles
• Includes 3/4" bearings×4 to adapt to larger axles
• Spacers (0.5"×4 and 1.5"×4) let you extend hub from 1.77" to 5.77"
• Washers and cotter pins secure alignment and prevent wobble

What terrain and loads can this flat-free wheel handle?

The tread pattern and solid polyurethane construction give dependable traction and puncture-free performance across many surfaces. It grips grass, gravel, dirt and compacted sand while resisting cuts and abrasions. Each wheel supports up to 300 lbs, making it suitable for heavy gardening and light contractor tasks.

• Non-slip tread with grooves for improved traction on wet or uneven ground
• Solid polyurethane resists wear, cracking, and punctures
• Rated capacity up to 300 lbs per wheel for small-vehicle loads
• Works on grass, stone roads, dirt, sand and cement surfaces

How durable is the rim, bearing assembly and overall construction?

This wheel pairs a thickened, single-piece welded steel rim with carbon steel bearings to withstand rough use. The rim and hub are engineered to avoid separation or bending under typical loads, while the polyurethane tread maintains shape and resists flat spots when rotated and not left under long static loads.

• Thickened steel rim with single-piece welds prevents rim deformation
• Carbon steel bearings built for frequent rolling and load cycles
• Solid polyurethane formula engineered for abrasion and crack resistance
• Avoid extended static loading to reduce potential flat-spotting

What’s included with the purchase and how does the adapter kit help?

The wheel arrives with the hub pre-installed and a full adapter kit so you can fit many axle types without buying extra hardware. Spacers adjust the hub length and bearing options let you change bore size, improving compatibility with a wide range of equipment brands and models.

• One 13x4.00-6 solid polyurethane tire on a 13" thickened steel rim
• Pre-assembled centered hub (1.77") with 5/8" bearings installed
