Marathon 11x4.00-5" Flat Free Lawnmower Tire on Wheel, 5" Hub, 1/2" Precison Ball Bearings

What It Is

This is a flat-free (non-pneumatic) lawnmower tire pre-mounted on a 5-inch hub with 1/2-inch precision ball bearings. It’s designed for zero-turn mowers, walk-behind mowers, and small utility trailers where a puncture-proof, low-maintenance wheel is needed.

Fitment & Compatibility

Before buying, verify these three things:

• Hub diameter: The center hole is 5 inches across. Measure your mower’s axle or spindle mount to confirm it fits.
• Bearing size: Uses 1/2-inch precision ball bearings. Check that your axle shaft is exactly 1/2 inch in diameter—no adapters included.
• Tire dimensions: 11x4.00-5 (11-inch overall diameter, 4-inch width, 5-inch rim). Confirm clearance on your deck or frame; flat-free tires run slightly stiffer and can rub if tolerances are tight.
• OEM vs aftermarket: This is a universal replacement—not a direct OEM fit for most brands (e.g., John Deere, Husqvarna, Toro). Cross-reference your original wheel’s hub size and bearing type.

Key Things to Know

• No maintenance: Flat-free means zero air pressure checks, no punctures, and no flats. Ideal for rough terrain or heavy use.
• Installation: Simple—slide onto axle, secure with a cotter pin or washer/nut. No special tools needed.
• Ride quality: Firmer than pneumatic tires; expect more vibration on uneven ground. Not ideal for turf or delicate lawns.
• Weight capacity: Typically rated for up to 300 lbs per wheel, but verify with Marathon’s specs for your specific load.

Should You Buy It

Buy this if you’re tired of fixing flats on a zero-turn or walk-behind mower used on gravel, dirt, or bumpy ground. Skip it if you need a soft ride for fine turf or if your mower requires a different hub size (e.g., 3/4-inch bearings or a 4-inch hub). At $27.40, it’s a solid value for durable, hassle-free wheels.
