Marathon 11x4.00-5 Flat-Free Lawnmower Tire on 5" White Steel Wheel — 1/2" Bearings, 300 lb Capacity

Marathon's 11x4.00-5 flat-free lawnmower tire on a white steel 5" wheel delivers airlike ride and handling without the worry of punctures.

Built to replace standard small mower tires, this pre-mounted assembly combines a molded flat-free tire with a centered 5" hub and 1/2" precision ball bearings for easy swap-in and smooth rolling. The tire is engineered to mimic the shock absorption and load capacity of an inflated tire while eliminating flats, leaks, and frequent maintenance. It’s a practical upgrade for zero-turns, garden tractors, and other yard machines where downtime matters.

Will this tire fit my mower?

Measure your current tire sidewall and hub to confirm compatibility: the listed size is 11x4.00-5 with a centered 5" hub and 1/2" bore bearings. If your old tire matches these specs, this Marathon assembly is a direct replacement; otherwise check adapter options or consult your mower manual.

• Size: 11x4.00-5 (diameter x width x rim)
• Hub: 5" centered hub that extends equally past the rim
• Bearing: 1/2" precision ball bearings pre-installed
• Recommended: verify sidewall markings and shaft diameter before purchase

How does the flat-free design affect ride and durability?

The tire uses a resilient solid compound that reproduces the cushioning of an air-filled tire while resisting punctures, ozone, and temperature extremes. Expect consistent handling and reduced service needs, with a smooth tread that’s non-marking and lighter than many other solid tire types.

• Ride feel similar to pneumatic tires without inflation
• Unaffected by sun, heat, or cold—less seasonal degradation
• Smooth tread for clean mowing and turf protection
• 300 lb load capacity per tire under typical use

How easy is installation and maintenance?

This wheel comes pre-mounted on a painted steel rim and includes 1/2" bearings, so most replacements are bolt-on and ready to roll. Bearings can be replaced via the manufacturer if they wear; store tires without load where possible to preserve shape during long-term storage.

• Pre-mounted on white steel wheel for fast swap-in
• Center hub extends equally for proper fitment and clearance
• Replacement bearings available from the manufacturer
• Not intended for highway use—designed for off-road lawn equipment

What performance limits and cautions should I consider?

While built for yard equipment, this flat-free tire is not rated for highway speeds or vehicle use beyond lawn and garden applications. Avoid using tires under constant heavy stationary load during storage, and confirm load needs if operating on uneven terrain or towing heavy attachments.

• Rated 300 lb load capacity—check combined axle loads
• Non-marking tread suitable for driveways and lawns
• Not a replacement for highway or high-speed tires
• Keep weight off tires in long-term storage when possible

Who is this for? If you maintain a zero-turn mower, garden tractor, or other small utility equipment and want a reliable, maintenance-free wheel that feels like a pneumatic tire, this Marathon 11x4.00-5 assembly is designed for you. It suits homeowners, landscapers, and equipment rental operations that prioritize uptime, predictable handling, and resistance to flats without the upkeep of air-filled tires.
