What It Is

This is a pair of 20x8.00-8 rear tire and wheel assemblies designed for riding lawn mowers and garden tractors. They are tubeless, 4-ply rated, and come pre-assembled with a 3/4" bore hub and 3/16" keyway for direct bolt-on replacement of worn or damaged rear tires.

Fitment & Compatibility

Before buying, confirm these measurements on your current wheel:

  • Tire size: Must be 20x8.00-8 (20" diameter, 8" wide, 8" rim). If your tire is 20x10-8 or 18x8.5-8, these won’t fit.
  • Hub offset: 3.5" offset. Measure from the mounting flange to the center of the tire tread. A mismatch can cause rubbing or poor alignment.
  • Bore diameter: 3/4" with a 3/16" keyway. Measure your axle shaft diameter – it must be 3/4" and have a keyway slot. If your axle is 5/8" or 1", these won’t fit.
  • Bolt pattern: 4-bolt on 4" center (standard for most riding mowers). Verify your wheel’s bolt circle.
  • Load capacity: 965 lbs per tire – sufficient for most residential riding mowers (e.g., John Deere, Cub Cadet, Husqvarna, Craftsman). Not for zero-turn mowers with offset axles.

Key Things to Know

  • Installation: Straightforward – remove old wheel, slide new one onto axle, align keyway with key, tighten lug nuts. No tire mounting or balancing required.
  • Quality: 4-ply rating offers decent puncture resistance for lawns, but not for rough terrain or heavy commercial use.
  • Common gotchas: The 3.5" offset is not universal – some mowers (especially older models) use 2.5" or 4" offset. Measure twice. Also, the keyway is pre-cut; if your axle doesn’t have a key, you’ll need to add one (sold separately).
  • Tubeless: No inner tube to replace, but rim must seal properly. Check for rim damage before installation.

Should You Buy It

Buy this if you need a direct replacement for a worn 20x8.00-8 rear tire on a standard riding mower with a 3/4" axle and 3.5" offset hub. It’s a solid value for residential use – easy to install, good load rating, and pre-assembled. Skip it if your mower uses a different tire size, offset, or axle diameter, or if you need a tire for a zero-turn mower.
