Marathon 4.00-6" Replacement Pneumatic Wheel Tire and Tube

Marathon 4.00-6" replacement pneumatic wheel tire and inner tube — a ribbed-tread, air-filled tire assembly sized to fit 6" rims and support loads up to 350 lb.

This replacement tire and tube pair is designed for small mobile equipment that uses 4.00-6" pneumatic wheels. The assembly combines a 4-ply rubber tire with a matching inner tube, delivering shock absorption and traction from a ribbed tread. It’s intended for use with manual inflation only and is suitable for utility carts, lawn equipment, hand trucks, and other off-highway applications where a pneumatic wheel improves ride and load handling.

Will this tire fit my wheel hub and rim?

Yes — this product is sized to mount on a 6" rim and is specified as a 4.00-6" tire with a 13" outside diameter. Confirm your existing rim diameter and tire width before purchasing to ensure a correct fit.

• Size: 4.00-6" (tire width and rim diameter standard)
• Outer diameter: 13" for compatibility checks
• Fits: rims labeled for 6" mounting
• Includes inner tube matched to the tire size

How durable is the Marathon tire for regular use?

The tire is constructed with a 4-ply rubber casing, offering a balance of durability and flexible sidewall performance for light-to-moderate loads. Its pneumatic design cushions impacts better than solid wheels, reducing vibration and protecting fragile cargo.

• 4-ply rubber construction for improved puncture and wear resistance
• Ribbed tread for steady ground contact and directional stability
• Not intended for highway or high-speed applications
• Manual pump inflation recommended to control pressure precisely

What load and inflation guidelines should I follow?

The tire assembly supports a maximum load of 350 pounds when inflated and used as intended. For safe operation, inflate with a manual pump to the pressure recommended for the tube and application, and avoid overloading beyond the specified capacity.

• Maximum load capacity: 350 lb per tire
• Inflation method: manual pump only (no air compressors recommended)
• Regularly inspect pressure and tread for wear or damage
• Not approved for highway or high-speed use

How easy is installation and maintenance?

Replacing the tire and tube is straightforward for users comfortable removing a wheel from small equipment. The package includes a compatible inner tube; basic tools and a manual pump are all that’s needed to mount and inflate the assembly.

• Includes inner tube paired to the tire size for a matched fit
• Basic wheel removal and mounting tools required
• Manual pump recommended for accurate pressure control
• Inspect valve stem and seating during installation for airtight fit

Who is this for? This Marathon 4.00-6" pneumatic tire and tube set is aimed at DIYers, landscapers, and small-vehicle owners who need a cost-effective replacement for worn pneumatic wheels on carts, hand trucks, ride-on tools, or utility trailers used off public roads. If you require a shock-absorbing wheel that improves handling and load cushioning while matching a 6" rim and 13" diameter profile, this assembly is a practical, easy-to-install option.
