GICOOL (1 Pack) 11x4.00-5 Tubeless Zero Turn Mower Tire, Riding Lawnmower Smooth Tread, 4 Ply

What It Is

The GICOOL 11x4.00-5 tubeless zero turn mower tire is a smooth-tread replacement tire designed for the front caster wheels of zero-turn riding mowers and some lawn tractors. Its smooth, non-aggressive tread is intended for flat, manicured lawns where turf damage is a concern.

Fitment & Compatibility

Before buying, confirm these three things:

• Tire size: Must be exactly 11x4.00-5 (11-inch outer diameter, 4.00-inch width, 5-inch rim). Measure your existing tire’s sidewall markings.
• Rim size: This tire fits a 5-inch diameter rim. Verify your wheel’s rim diameter, not the wheel hub.
• Application: Designed for front caster wheels on zero-turn mowers (e.g., Toro, John Deere, Husqvarna, Bad Boy, Gravely, Cub Cadet). Not for drive wheels or heavy-duty off-road use.

Check your mower’s owner manual or measure the old tire’s dimensions. This is an aftermarket part, not OEM, but dimensions are standard.

Key Things to Know

• 4-ply rating: Provides adequate puncture resistance for residential use but not for rough terrain or heavy debris. Avoid rocky or uneven ground.
• Tubeless design: No inner tube required; mounts directly to a compatible tubeless rim. Ensure your rim is clean and bead-seat is rust-free.
• Installation: Moderate difficulty—requires tire irons and some elbow grease. A tire machine or shop is easier for DIYers.
• Common gotcha: The smooth tread offers less traction on slopes or wet grass than a ribbed or knobby tire. Ideal for flat, dry lawns only.

Should You Buy It

Buy this tire if you need a budget-friendly, direct replacement for a worn front caster tire on a zero-turn mower used on flat, well-maintained lawns. Skip it if you mow on hills, wet grass, or rough terrain—you’ll want a ribbed or more aggressive tread for better traction and durability.
