Swisher 18784 Replacement 20x10-10 Tire/Wheel for Select Zero Turn Mowers

What It Is

The Swisher 18784 is a replacement 20x10-10 tire and wheel assembly designed for select zero-turn mowers, providing a direct bolt-on replacement for worn or damaged rear tires. It’s intended for residential and commercial mowers that use this common tire size.

Fitment & Compatibility

Before buying, verify these three things:

• Tire size: Must be 20x10-10 (20-inch diameter, 10-inch width, 10-inch rim). Measure your current tire’s sidewall markings.
• Bolt pattern: The wheel uses a 4-bolt pattern on a 4-inch center (4 on 4). Confirm your mower’s hub matches.
• Model compatibility: Swisher states this fits many zero-turn mowers, including select Swisher, Bad Boy, Hustler, and others. Check your owner’s manual or measure the existing wheel’s offset (backspacing) to ensure clearance against the frame or deck. It’s an aftermarket replacement, not OEM, so verify lug nut size (typically 1/2-20 or 5/8-18).

Key Things to Know

• Quality: Users report decent tread life for residential use, but the tire is bias-ply, not radial—so expect a firmer ride on rough terrain.
• Installation: Direct bolt-on if fitment matches. No special tools needed beyond a socket wrench and jack. Torque lug nuts to 55-70 ft-lbs.
• Common gotcha: The tire may have a slightly different tread pattern or sidewall profile than your original. This usually doesn’t affect performance, but check clearance if your mower has tight rear tire space.
• Price point: At $124.95, it’s mid-range—cheaper than OEM but not the budget option. It includes the wheel, so no need to swap your old rim.

Should You Buy It

Buy this if you need a reliable, direct-fit replacement for a 20x10-10 rear tire on a zero-turn mower and want a complete wheel assembly without hunting for separate parts. It’s best for residential mowing where a firm ride is acceptable, and you’re comfortable verifying bolt pattern and offset. Skip it if you need a radial tire for heavy commercial use or require an exact OEM match.
