(Set of 2) 11x4.00-5 Flat Proof, Smooth Semi Pneumatic Assembly Replacement for ARIENS: 01588100 & 07100124, DIXON: 17080, JOHN DEERE: AM101589, TORO: 104-1170

What It Is

This is a set of two 11x4.00-5 flat-proof (puncture-resistant) semi-pneumatic wheel assemblies, designed as a direct replacement for zero-turn mowers and lawn tractors. They eliminate flat tires on machines used in rough terrain or debris-heavy areas.

Fitment & Compatibility

• Check your tire size: Must be exactly 11x4.00-5 (diameter x width x rim size). Measure your current tire’s sidewall stamp.
• Bolt pattern: These use a 5/8" bore (center hole) with a 2.875" bolt circle (3-bolt pattern). Confirm your hub matches before ordering.
• OEM cross-reference: Fits ARIENS (01588100, 07100124), DIXON (17080), JOHN DEERE (AM101589), TORO (104-1170). Not universal—verify your model against these numbers.
• Deck size / machine type: Common on 42"-60" zero-turn mowers (e.g., Toro Z Master, John Deere Z900 series, Ariens Zoom). Not for push mowers or small tractors with 4.10/3.50-4 tires.

Key Things to Know

• Flat-proof = no air: Solid foam core means zero maintenance, but a harsher ride on pavement. Best for yards with sticks, nails, or rocks.
• Installation difficulty: Easy—remove old wheel, bolt on new. No tire mounting or inflation needed. Expect 10-20 minutes per side.
• Weight difference: Heavier than pneumatic (about 8-10 lbs each). May affect steering effort slightly, but not a problem for most riders.
• Common gotcha: These are semi-pneumatic (hollow, not solid rubber like a caster wheel). They can still wear out over time, but won’t go flat from punctures.

Should You Buy It

Buy if you’re tired of fixing flats in a commercial or heavy-use residential zero-turn. Skip if you need a cushioned ride for smooth lawns, or if your mower uses a different bolt pattern or tire size (e.g., 13x5.00-6). At $126, it’s a fair price for a durable, no-maintenance set that fits common Ariens, John Deere, and Toro models.
