NoAir® (2) Flat Free Tire Assemblies 11x4.00-5 Fits Scag Liberty Freedom Z 485207

What It Is

The NoAir® (2) Flat Free Tire Assemblies 11x4.00-5 are a pair of non-pneumatic, maintenance-free tires designed to replace the rear wheels on Scag Liberty and Freedom zero-turn mowers. They eliminate flats and air pressure checks, ideal for commercial or heavy residential use on rough terrain.

Fitment & Compatibility

• Exact fit: Designed for Scag Liberty (model years 2010+) and Freedom Z mowers. OEM part number cross-reference: 485207.
• Measurements: 11-inch outer diameter, 4.00-inch width, 5-inch center hub hole. Verify your current tire size is the same—measure the sidewall markings or the rim diameter.
• Deck size: Works with 48", 52", and 61" deck models, but confirm your mower’s rear tire size matches (some older models may use 10x4.00-5 or 11x4.00-6).
• Axle compatibility: 5/8-inch axle diameter with a 3/4-inch wide bearing. Check your axle shaft and bearing width before ordering.
• Aftermarket vs OEM: These are direct replacements for the OEM pneumatic tires. No adapters or modifications needed.

Key Things to Know

• Installation: Easy bolt-on—remove the old tire, slide the new assembly onto the axle, and secure with the existing hardware. No inflation or tube fitting required.
• Ride quality: Slightly stiffer than pneumatic tires, which can transmit more vibration on bumpy ground. Acceptable for most mowing, but may feel harsh on uneven lawns.
• Weight: Heavier than pneumatic equivalents (about 18 lbs per tire). This adds unsprung weight, potentially affecting traction on steep slopes.
• Durability: Flat-free construction means no punctures, but the solid foam core can degrade over time if exposed to extreme heat or UV. Store mower indoors when not in use.

Should You Buy It

Buy these if you’re tired of fixing flats on your Scag zero-turn, mow over rough or debris-filled ground, and want a maintenance-free option that lasts years. Skip them if you prioritize a cushioned ride for delicate turf or need lighter tires for steep hills.
