Marathon 20" Flat-Free Replacement Tire Assembly for Rubbermaid Big Wheel — Black Composite Wheel, Pre-mounted with Bearings

Marathon's 92010 is a pre-mounted 20" flat-free tire and heavy-duty composite wheel designed to replace air-filled tires on Rubbermaid Big Wheel and similar two-wheeled outdoor carts.

If you rely on a Big Wheel-style cart, dock or yard wagon for hauling, a sudden flat tire can stop work and cost time. This Marathon assembly uses solid polyurethane foam to replicate the feel of an air-filled tire while eliminating punctures and inflation maintenance. It arrives ready to install on a black composite spoked wheel with bearings included to fit common axle sizes.

Will this replace my Rubbermaid Big Wheel tires easily?

Yes — the 92010 is built to be a drop-in replacement for many Big Wheel-style carts, provided your axle and hub dimensions match. Marathon pre-installs 3/4" bearings and supplies 5/8" bearings so you can swap to the size your axle requires. Always measure axle diameter and hub length before ordering to ensure a correct fit.

• Pre-mounted 20 x 2.0 flat-free tire on composite wheel for quicker swap
• 3/4" bearings installed; 5/8" bearings included for customization
• 2.465" centered hub dimension — confirm against your cart hub
• Instructions: remove old wheel, place new assembly, install retaining hardware

How does a flat-free polyurethane tire compare to an air-filled tire?

The Marathon flat-free tire uses solid polyurethane foam engineered to reproduce the bounce and handling of an air-filled tire without the risk of punctures or the need to inflate. The compound resists degradation from weather and sunlight, so it keeps reliable rolling performance season after season. The knobby, non-marking tread protects working surfaces while improving traction on uneven ground.

• Solid polyurethane foam for consistent feel and no punctures
• Knobby, non-marking tread to guard floors and improve grip
• Weather-resistant construction that won’t dry-rot or leak

What load and use limits should I expect?

This wheel assembly is rated to support up to 250 pounds and is intended for outdoor carts, dock wagons, and yard equipment. It is not designed for highway or high-speed vehicle use. For heavy commercial needs or unusual axle configurations, confirm compatibility with your equipment before purchase.

• 250 lb load capacity suitable for household and light commercial hauling
• Not for highway or motor-vehicle applications
• Recommended for lawn & garden carts, marina carts, and Rubbermaid Big Wheel replacements

What parts and installation steps are included?

The package contains the tire already mounted to a black composite spoked wheel, 3/4" bearings installed in the hub, and an extra pair of 5/8" bearings for axle size flexibility. No inner tube or inflation tools are required. Typical installation is a simple wheel swap that should be achievable with basic hand tools.

• Pre-mounted 20" flat-free tire and composite wheel
• 3/4" bearings installed; 5/8" bearings included for alternate axles

Who is this for? If you own a Rubbermaid Big Wheel cart, dock or marina cart, or any two-wheeled outdoor wagon that uses a 20 x 2.0 wheel and matching hub, Marathon’s 92010 is a practical upgrade to avoid flats and maintenance downtime. It’s especially useful for homeowners, landscapers, marina staff, and anyone who needs a dependable, low-maintenance wheel replacement that keeps working surfaces clean and equipment in service.
