20x8.00-8 Gray Lawn Mower Wheel - Set of 2-3/4 Inch Axle, 2.90 Inch Hub

What It Is

This is a set of two 20x8.00-8 gray lawn mower wheels with a 3/4-inch axle diameter and a 2.90-inch hub length. Designed for zero-turn mowers, garden tractors, and large walk-behinds, they serve as durable replacement wheels for mowers with heavy-duty rear or front axle requirements.

Fitment & Compatibility

Before buying, verify these measurements:

• Axle size: Must be 3/4-inch diameter. If your mower uses a 5/8-inch or 1-inch axle, these won’t fit.
• Hub length: 2.90 inches. Measure your existing hub depth to ensure the wheel sits flush and doesn’t rub against the frame or deck.
• Tire size: 20x8.00-8 (20-inch outer diameter, 8-inch width, 8-inch rim). Check your current tire sidewall for matching numbers.
• Bolt pattern: These are universal fit for 3/4-inch axles, but confirm your mower uses a standard keyed or pin-style axle. No universal bolt pattern—these slide onto the axle and are secured with a cotter pin or clip.
• Common brands/models: Often compatible with Gravely, Husqvarna, John Deere, Cub Cadet, and Bad Boy zero-turn models. Cross-check with your mower’s OEM part number (e.g., Gravely 09200400 or Husqvarna 532420001). Not guaranteed for all aftermarket decks—measure first.

Key Things to Know

• Quality: Gray brand wheels are known for durable steel rims and tough rubber. 4.7 stars from 234 reviews suggests reliable build, but check for reviews mentioning rim rust or tire wobble on heavy mowers.
• Installation: Easy DIY—remove old wheel, slide on new one, secure with existing hardware. No special tools needed. Allow 30 minutes for both wheels.
• Gotcha: The 2.90-inch hub length may be too short for mowers with wide axle mounts. If your hub is longer, you’ll need spacers (not included). Also, these are not tubeless—use a tube if rim leaks.
• Load capacity: Typically rated for up to 400-500 lbs per wheel, suitable for most residential zero-turns. Not for commercial-grade mowers over 1,000 lbs.

Should You Buy It

Buy this set if you need a direct, drop-in replacement for a 3/4-inch axle on a residential zero-turn or garden tractor and want solid quality without overspending. Avoid if your mower has non-standard axle sizes, requires a different bolt pattern, or is a heavy commercial unit—measure first to avoid returns.
