Marathon 16x6.50-8 Flat-Free Tire on 3" Hub Wheel — 3/4" Bushings, 400 lb Capacity

The Marathon 16x6.50-8 flat-free tire on a white steel wheel delivers air-like ride and 400 lb load capacity without ever needing inflation.

If you need a durable replacement wheel for zero-turn mowers, garden tractors, or utility carts that won’t lose pressure or require patching, this Marathon assembly is built to match the handling of a pneumatic tire while eliminating flats. The unit pairs a solid polyurethane foam tire with a centered 3" hub and commercial 3/4" oil-infused bushings for long service life on turf and paved surfaces. Before ordering, verify your existing tire and hub measurements to ensure a correct fit—this model measures approximately 15.8" overall diameter and 5.9" tread width.

How does this flat-free wheel compare to a standard air-filled tire?

The Marathon flat-free design is engineered to mimic the resilience and load distribution of a filled tire but uses solid polyurethane foam instead of air. That means you get consistent ride quality, no maintenance for inflation, and zero downtime from punctures. It’s non-marking and tuned for low-ground-pressure performance on lawns.

• Solid polyurethane construction replicates pneumatic feel without flats.
• Turf tread offers balanced traction and minimal grass scuffing.
• Non-marking material keeps lawns clean while mowing or towing.

Will this wheel fit my mower or equipment?

Fit depends on your current tire and hub dimensions; this model is sized to replace common 16x6.50-8 lawn tires. The wheel has a centered 3" hub and accepts 3/4" commercial-grade bushings. Check your machine’s axle type, hub offset, and clearance to confirm compatibility before purchase.

• Overall tire diameter: ~15.8"; tread width: ~5.9".
• Hub: 3" centered bore; bushings: 3/4" oil-infused commercial type.
• Designed as a lawn-mower/utility replacement, not for highway use.

How much weight and what surfaces can this wheel handle?

The wheel supports moderate loads—rated for up to 400 pounds—making it suitable for most residential and light commercial mowing and towing tasks. Its turf-oriented tread balances traction and maneuverability, protecting grass while maintaining control on driveways or packed earth. Avoid sustained high-speed or highway use; it’s optimized for low-speed equipment.

• Load capacity: 400 lb per wheel under normal conditions.
• Turf tread designed for lawns, garden paths, and light yard work.
• Not engineered for highway or high-speed applications.

What maintenance and installation should I expect?

Because the tire is a solid polyurethane assembly, routine maintenance is minimal—no inflation checks or patching required. Installation follows standard wheel replacement steps: remove the old wheel, confirm hub and bushing match, and secure the new wheel to the axle. Using the correct bushing size and keeping fasteners torqued per your machine’s manufacturer will extend service life.

• No air pressure upkeep—solid tire means no flats or patches.
• Replace using a centered 3" hub and 3/4" bushings as required.
• Inspect mounting hardware and re-torque periodically for safety.

Who is this for: The Marathon 16x6.50-8 flat-free tire on wheel is aimed at homeowners, landscapers, and light commercial operators who want dependable, low-maintenance replacement wheels for lawn mowers, garden tractors, and utility carts. If you prioritize zero-flat reliability, turf-friendly handling, and a 400 lb load rating in a standard 16x6.50-8 size, this wheel is a practical upgrade—just confirm fitment against your current hub and axle setup before purchasing.
