AR-PRO 11x4.00-5 Lawn Mower Tire and Wheel Assembly, 4-Ply Pneumatic Rib Tread, 3.4" Centered Hub, 3/4" Bearings, Compatible with Zero-Turn Mowers and Lawn Equipment (1-Pack)

What It Is

The AR-PRO 11x4.00-5 tire and wheel assembly is a replacement front or caster tire for zero-turn mowers and lawn equipment, featuring a 4-ply pneumatic rib tread design for smooth rolling and traction on turf. It’s packaged as a single assembly (tire mounted on a steel wheel) ready to bolt on.

Fitment & Compatibility

Before buying, confirm these three measurements:

• Tire size: 11x4.00-5 (11" outer diameter, 4" width, 5" rim diameter). Compare to your current tire’s sidewall markings.
• Hub dimensions: 3.4" centered hub (bolt circle diameter) with 3/4" bearings (inner diameter). Measure your spindle or axle shaft—if it’s 3/4", this fits. The centered hub means the wheel is symmetrical; offset hubs require different models.
• Bolt pattern: The hub has a 4-bolt pattern on a 3.4" circle. Verify your mower’s bolt pattern matches (common on zero-turn brands like Ariens, Gravely, Husqvarna, and some Toro models). If your mower uses a keyed axle or a different bearing size, this won’t work.

Check your owner’s manual or measure the existing wheel assembly. This is an aftermarket part, not OEM—fitment varies by brand and model year.

Key Things to Know

• Quality: 4-ply rating is standard for residential zero-turns; holds up on grass, dirt, and light gravel. Not for heavy commercial use or rough terrain.
• Installation: Easy—remove the old wheel, slide this onto the spindle, and secure with the existing bolt/nut. No tire mounting required. May need a spacer if your mower uses a different hub depth.
• Common gotchas: The 3.4" hub is centered, so if your original wheel had an offset hub (e.g., some John Deere models), this will misalign the tire with the mower deck. Also, the 3/4" bearing is for straight axles—won’t fit on a tapered or keyed spindle without modification.
• Pressure: Inflate to 20-25 PSI max; overinflating reduces traction and ride quality.

Should You Buy It

Buy this if you have a zero-turn mower with a 3/4" straight axle, a 4-bolt 3.4" hub pattern, and need a reliable, affordable replacement front tire. It’s a solid value for residential use, but skip it if your mower requires an offset hub, a different bearing size, or a heavy-duty tire for commercial cutting.
