Marathon 01420P 3" hub, 3/4" bushings 11x4.00-5" Flat Free Lawnmower Tire on Wheel

What It Is

The Marathon 01420P is a flat-free (never-flat) lawn mower tire pre-mounted on a 3-inch steel wheel hub with 3/4-inch bushings, sized 11x4.00-5. It’s designed for zero-turn mowers, lawn tractors, and commercial mowers that need a puncture-proof front or caster tire.

Fitment & Compatibility

Before buying, verify three things:

• Wheel hub size: The hub is 3 inches wide with a 3/4-inch bore (bushing included). Measure your spindle or axle diameter—most zero-turn mowers and tractors use 3/4-inch axles, but some use 5/8-inch or 1-inch. If yours doesn’t match, you’ll need a different bushing or wheel.
• Tire size: 11x4.00-5 (11 inches tall, 4 inches wide, 5-inch rim diameter). Check your current tire’s sidewall for these numbers. This size is common on front wheels of many residential and commercial zero-turns (e.g., Toro, John Deere, Cub Cadet, Gravely, Husqvarna).
• Bolt pattern: The wheel has a 4-bolt pattern with 4-inch center spacing (4 on 4). Measure from the center of one bolt hole to the center of the opposite hole—must be exactly 4 inches. If your mower uses a different pattern (e.g., 5 on 4.5), this wheel won’t fit.
• OEM vs aftermarket: This is an aftermarket replacement. It’s not OEM-specific but fits most mowers that use the above measurements. Check your mower’s manual or measure the existing wheel to avoid returns.

Key Things to Know

• No maintenance: Flat-free means no air, no punctures, no pressure checks. Great for rough terrain or debris-heavy yards, but the tire is heavier than pneumatic—expect a slightly stiffer ride.
• Installation is simple: Unbolt the old wheel, bolt on the new one. No tire mounting needed. Torque lug nuts to 35-45 ft-lbs. The included bushings fit standard 3/4-inch axles; if your axle is smaller, you may need reducer bushings (not included).
• Durability vs comfort: The solid rubber compound is tough and long-lasting, but it doesn’t absorb bumps like air-filled tires. On uneven ground, the mower may feel more jarring. It’s also slightly smaller in diameter than some OEM pneumatic tires (check clearance).
• Load capacity: Rated for up to 300 lbs per tire—fine for most residential and light commercial mowers. Heavy commercial zero-turns with added attachments may exceed this.

Should You Buy It

Buy this if you’re tired of fixing flats on your zero-turn or lawn tractor front tires and want a low-maintenance, long-lasting solution. It’s best for flat, well-maintained lawns or areas with thorns and debris. Avoid if you need a cushioned ride on rough terrain or if your axle/bore size doesn’t match 3/4-inch. For the price, it’s a solid, no-hassle replacement that will outlast most pneumatic tires.
