MaxAuto 9x3.50-4 Flat Free Lawn Mower Tires, 9x3 50 4 Lawnmower Wheel Assemblies, Smooth Tread Zero Turn Tire for King Kutter/Scag/Kubota Riding Mowers, 3.5" Centered Hub, 3/4" Bushings, 2 Pack

What It Is

The MaxAuto 9x3.50-4 Flat Free Lawn Mower Tires are a pair of non-pneumatic, smooth tread wheel assemblies designed for zero-turn and riding mowers. They eliminate flats and maintenance, making them ideal for light-duty mowing on hard, flat terrain.

Fitment & Compatibility

Before buying, check these measurements:

• Tire size: 9x3.50-4 (9" outer diameter, 3.50" width, fits 4" rim).
• Hub: 3.5" centered hub, with included 3/4" bushings (for 3/4" axle). Verify your mower’s axle diameter; if not 3/4", you may need adapter bushings.
• Bolt pattern: 4-bolt hub (common on most zero-turns). Measure bolt circle diameter (typically 4" on 4-bolt patterns).
• Weight capacity: Rated for ~300 lbs per tire—adequate for most residential mowers but not heavy commercial decks.
• Brand fit: Works with King Kutter, Scag, Kubota, and many others, but always cross-reference your mower’s OEM tire size (e.g., 9x3.50-4) and hub specs. Aftermarket only; not OEM direct replacements for all models.

Key Things to Know

• Installation difficulty: Moderate. You’ll need a socket set and possibly a pry bar to fit the bushings. Some users report tight fit on hubs—file or sand for easier install.
• Ride quality: Firm and bouncy on rough ground due to solid rubber. Not recommended for bumpy lawns or slopes; best on flat, manicured turf.
• Durability: Flat-free design prevents punctures, but tread is smooth and wears faster on pavement. Good for 2-3 seasons of light use.
• Common gotcha: The included 3/4" bushings may not fit all axles (e.g., some Scag models use 5/8" or 1"). Measure your axle before ordering; you may need separate bushings.

Should You Buy It

Yes, if you want a budget-friendly, maintenance-free tire for a residential zero-turn mower on flat, smooth lawns. Skip it if you need high traction on hills, rough terrain, or have a heavier commercial deck—look for a wider, pneumatic tire instead.
