11x4.00-5 Flat Free Lawn Mower Tires and Wheels 3/4" 5/8" 1/2" Ball Bearings, 3.25"-5.5" Centered Hub 11x4-5 Zero Turn Mower Front Tires, Smooth Wheels for Commercial Grade Lawn

What It Is

This is a set of two 11x4.00-5 flat-free (never-flat) tires with wheels, designed primarily for zero-turn mower front wheels but also compatible with some lawn tractors, wheelbarrows, and hand trucks. The solid foam construction eliminates flats, making them ideal for commercial-grade mowing where downtime from punctures is unacceptable.

Fitment & Compatibility

Before buying, verify these four measurements:

• Tire size: Must be 11x4.00-5 (11" outer diameter, 4" width, 5" rim diameter). Measure your current tire’s sidewall stamp.
• Bearing size: These wheels come with 1/2", 5/8", and 3/4" ball bearing adapters. Check your axle diameter (most zero-turn fronts use 5/8" or 3/4").
• Hub center hole: The hub is centered and fits axles from 3.25" to 5.5" wide. Measure the distance between your mower’s fork legs.
• Bolt pattern: None – these are axle-mount wheels with a smooth hub, no lug nuts. They slide onto a single axle bolt or pin.

Common compatible models: Gravely ZT HD, Scag Turf Tiger, Hustler Super Z, Toro Z-Master, and many commercial zero-turns with 11x4-5 front tires. Not for riding tractors with 4-bolt wheel hubs.

Key Things to Know

• No maintenance: Flat-free means no air pressure checks, no punctures, and no patching. But the ride is noticeably stiffer than pneumatic tires – expect more vibration on rough ground.
• Weight difference: These are heavier than pneumatics (about 6-8 lbs each). This can slightly affect mower balance and turn radius on some models.
• Installation: Usually a 10-minute job – remove axle bolt, slide old wheel off, slide new one on, reinstall bolt. You may need a socket or wrench for the axle nut. No special tools required.
• Durability: Rated for commercial use, but the foam can degrade over 3-5 years under constant UV exposure and heavy loads. Keep them out of direct sun when stored.

Should You Buy It

Buy these if you mow commercially or have a zero-turn that constantly gets flats from sticks, thorns, or debris. They’re a solid upgrade for anyone tired of patching tubes. Skip them if you mow on delicate turf (the stiff ride can leave slight ruts) or if your axle width falls outside 3.25–5.5 inches – measure first.
