20x8.00-8 Reaper Lawn Mower Wheel - Set - 3/4 Inch Axle, 2.90 Inch Hub

What It Is

This is a set of two 20x8.00-8 rear wheels and tires designed for heavy-duty lawn mowers, zero-turn mowers, and large garden tractors that need a wide, low-profile tire for stability and traction on uneven terrain or slopes.

Fitment & Compatibility

Before buying, confirm these three measurements:

• Axle size: Must be 3/4 inch diameter (common on many zero-turn and commercial mowers). If your axle is 5/8” or 1”, these won’t fit.
• Hub length: The hub is 2.90 inches long. Measure your existing hub depth to ensure the wheel sits flush and clears brake calipers or frame brackets.
• Tire size: 20x8.00-8. This is a 20-inch outer diameter, 8-inch wide tire on an 8-inch rim. Verify your deck clearance—especially for zero-turn mowers with side-discharge chutes.

This set is aftermarket, not OEM. It fits many Reaper models and brands like Bad Boy, Hustler, Gravely, and Scag, but always check your mower’s manual or measure your current wheel—don’t rely on brand name alone.

Key Things to Know

• Quality: 4.5 stars from 26 reviews suggests solid build. Tires are likely 4-ply rated for puncture resistance; expect good wear on turf and gravel but not extreme off-road.
• Installation: Easy bolt-on if axle and hub match. You’ll need a socket and torque wrench—no special tools. Check that lug nuts are torqued to manufacturer spec (typically 50-70 ft-lbs).
• Gotcha: The 2.90-inch hub is longer than some OEM hubs. If your mower has tight clearances near the axle, the extra hub length may rub against the frame or belt guard. Measure clearance before installing.
• Set includes two wheels/tires but no lug nuts or valve stems—buy those separately if yours are worn.

Should You Buy It

Buy this set if you need durable, wide rear tires for a 3/4-inch axle mower and your hub clearance is at least 3 inches. It’s a good value for replacing worn or damaged wheels on zero-turn or large garden tractors, especially if you want a no-fuss bolt-on upgrade. Skip it if your axle size or hub length doesn’t match exactly—returning oversize wheels is a hassle.
