Qualipo 13" x 4.00-6 Solid Tires Replacement Wheels — 2-Pack Preassembled with Adjustable Hub Adapters & 5/8"–3/4" Bearings

These are two pre-assembled 13" x 4.00-6 flat-free replacement wheels with adjustable hub adapters and both 5/8" and 3/4" bearing options for gorilla carts, garden wagons, wheelbarrows and similar utility equipment.

When your lawn cart or wheelbarrow needs a dependable, maintenance-free wheel upgrade, the Qualipo 13" 4.00-6 solid tires provide a rugged, puncture-proof alternative to pneumatic tires. Built from dense polyurethane foam and fitted to a steel rim with heavy-duty bearings, this two-wheel set is designed to resist flats, reduce vibration, and adapt to a variety of hub bores using the included adapter kit.

How do these solid tires fit my Gorilla Cart or garden equipment?

The wheels arrive pre-mounted on 6" rims with a centered hub that can be adjusted to match your axle setup. Included spacers and extra bearings let you convert the 1.8" hub length up to 5.8" and accept either 5/8" or 3/4" bore applications. Always measure your current wheel hub and bearing diameter before installation to ensure compatibility.

• Tire diameter: 13"; tire width: 4.00-6 profile
• Centered hub initial length: 1.8"; adjustable to 5.8" with kit
• Bearings included: four 3/4" plus adapters for 5/8" use
• Rim diameter: 6"; load capacity per wheel: up to 300 lb (136 kg)

What performance can I expect compared to air-filled tires?

These solid polyurethane tires eliminate the risk of punctures and maintain consistent traction across rough yards and work sites. Their serrated tread pattern improves grip on dirt and gravel while minimizing turf scuffing, and the steel rims with quality bearings provide smoother rolling and better vibration damping than low-grade wheel assemblies.

• Flat-free construction for no-maintenance use
• Serrated tread for improved off-road traction
• Steel rim and ball bearings for stability and reduced wobble
• Better vibration reduction versus basic plastic wheels

How easy is installation and what comes in the box?

Installation is straightforward: remove the old wheel, fit the hub over your axle, and secure with pins or retaining hardware. The package includes two fully assembled 13" solid wheels plus an adapter kit to accommodate different axle and bearing sizes, so you usually won’t need extra parts.

• 2 x 13" 4.00-6 solid tire & wheel assemblies
• 4 x 3/4" bearings and adapters for 5/8" where required
• 4 x 0.5" nylon spacers and 4 x 1.5" nylon spacers
• 4 retaining spacers/pins for secure mounting

How durable are these wheels and what warranty is included?

Constructed from solid polyurethane and fitted to steel rims with heavy-duty bearings, these wheels are built for frequent outdoor use and rough terrain. Qualipo supports the product with a two-year warranty, offering coverage against manufacturing defects and giving added confidence for routine garden and utility tasks.

• Solid polyurethane resists punctures and weathering

• Steel rims strengthen load handling capacity
