Marathon 20" Tire & Wheel Assembly 2-Pack — Flat-Free 20-inch Pre-Mounted Wheels with Centered Hub

Marathon's 92010-2PK is a ready-to-install, flat-free 20" tire and wheel assembly sold as a two-pack to replace air-filled wheels on Rubbermaid Big Wheel carts and similar outdoor wagons.

These pre-mounted wheels combine a solid polyurethane foam tire with a heavy-duty composite spoked rim, a centered 2.465" hub, and 3/4" ball bearings installed (plus extra 5/8" bearings included) so you can swap out worn or punctured wheels quickly without fabricating parts. The knobby, non-marking tread gives grip on uneven ground while resisting weathering, and the foam construction replicates the feel of an air tire without flats, pumps, or inner tubes.

How do these wheels install and fit my cart?

Installation is straightforward: slide the assembled wheel onto your axle and secure with the appropriate hardware for your cart. Verify your axle diameter and hub length before purchase — the wheel ships with 3/4" bearings installed and 5/8" bearings included for compatibility adjustments.

• Pre-mounted wheel and tire reduce installation steps
• Included 5/8" bearings for alternate axle sizes
• Centered 2.465" hub for common cart configurations
• Simple swap for air-filled or damaged wheels

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

The polyurethane foam core is engineered to mimic the rebound and handling of a pneumatic tire while remaining puncture-proof. You avoid downtime from flats and the maintenance of tubes and pumps, yet retain comfortable rolling over yard, dock, or gravel surfaces.

• Solid foam provides consistent ride quality without inflation
• Knobby tread offers traction across varied surfaces
• Non-marking compound protects decks and floors
• Durable in wet and outdoor environments—no tube to replace

Are these wheels durable and what load capacity do they support?

Each Marathon assembly is designed for heavy-duty outdoor use and resists degradation from sun, moisture, and physical wear. The product carries a 250-pound load capacity per wheel, making it suitable for many garden and equipment carts, though not intended for highway or high-speed applications.

• Heavy-duty composite spoked rim resists bending
• Polyurethane foam tire resists cracking and weathering
• Ball bearings installed to reduce rolling resistance
• Rated for typical yard, marina, and utility cart loads

What should I check before buying to ensure compatibility?

Measure your current wheel's outside diameter, hub center spacing, and axle diameter to confirm a fit. Compare those measurements to the Marathon wheel's 20" diameter, 2.465" centered hub, and the bearings provided to avoid returns or modifications.

• Confirm 20" outside tire diameter matches your cart
• Check axle diameter against the installed 3/4" bearings
• Use included 5/8" bearings if your axle is smaller
• Verify clearance and mounting hardware type on your cart

Who is this for: These Marathon 20" flat-free wheel assemblies are intended for homeowners, landscapers, marina operators, and small-business users who want a low-maintenance upgrade for Rubbermaid Big Wheel carts, dock carts, yard wagons, and similar two-wheeled utility equipment. If you need a reliable, weather-resistant replacement that eliminates flats and provides comfortable rolling without frequent upkeep, this two-pack offers an economical, easy-to-install solution.
