Marathon Pneumatic Tire & Wheel Assembly 4.10/3.50-4 (10.2") Pre-mounted, 300 lb Capacity

The Marathon 20011 is a pre-mounted 4.10/3.50-4 pneumatic tire and wheel assembly built to replace worn wheels on hand trucks and utility equipment quickly and reliably.

This single assembly pairs a 10.2-inch tube-type tire with a durable steel wheel and is designed to restore mobility to appliances like compressors, generators, pressure washers, blowers, dollies and garden carts. It arrives ready to install, with bearings and a grease fitting included, offering a straightforward alternative to rebuilding an old hub or buying specialized wheels. It is intended for off-road and equipment use only, not for highway driving.

What measurements and fit points determine compatibility?

Confirming a correct match requires checking the tire size on the sidewall and measuring hub dimensions on your existing assembly. The Marathon 20011 uses a 3/4" axle bearing spacing with a 2.25" hub offset, so ensure your frame and axle clearances accommodate those specs.

• Nominal tire diameter: 10.2 inches (4.10/3.50-4)
• Hub offset: 2.25 inches
• Bearing bore/axle size: 3/4 inch
• Tube-type tire: requires inner tube replacement when servicing

How does this assembly perform under load and terrain?

The wheel is rated to support up to 300 pounds, balancing strength and maneuverability for common utility tasks. A sawtooth tread pattern improves grip on grass, compacted soil, and workshop floors while still rolling smoothly for easier handling.

• Load capacity: 300 pounds per wheel
• Tread: sawtooth design for traction and low rolling resistance
• Pneumatic tire: cushions shocks on uneven ground
• Pre-mounted on solid steel wheel for durability

What are the maintenance and installation considerations?

The Marathon 20011 ships pre-mounted so you can swap it into place quickly; basic tools are all that’s needed. The assembly includes grease fittings and standard bearings, letting you lubricate and inspect the hub periodically to extend service life.

• Comes pre-mounted for faster replacement
• Includes grease fitting for hub lubrication
• Tube-type tire: keep a spare inner tube on hand
• Check axle diameter and hub clearance before installation

Who this is for: The Marathon 20011 is aimed at homeowners, landscapers, contractors and anyone who needs a dependable replacement wheel for portable equipment and hand trucks. If you maintain pressure washers, generators, compressors, garden carts or dollies and want a cost-effective, easy-to-install solution that restores mobility and traction, this assembly is a practical choice.
