(2-Pack) 20x8.00-8 Rear Tire and Wheel Assemblies - 4 Ply Tubeless Tire Compatible Replacement for Riding Lawn Mowers - 3/4" Borehole, 3.5" Offset Hub and 3/16" Keyway

What It Is

This is a pair of 20x8.00-8 rear tire and wheel assemblies designed for riding lawn mowers, zero-turn mowers, and garden tractors. They come pre-mounted on a steel wheel with a 3/4" bore, 3.5" offset hub, and 3/16" keyway, ready to bolt on.

Fitment & Compatibility

Before buying, confirm these four measurements:

• Tire size: Must be 20x8.00-8 (20" diameter, 8" wide, 8" rim). Common on many Craftsman, Husqvarna, John Deere, Troy-Bilt, and MTD models.
• Bore size: 3/4" (0.75") – measure your axle shaft diameter. If your axle is 5/8" or 1", these won’t fit.
• Hub offset: 3.5" – the distance from the wheel mounting face to the center of the tire. Measure your old wheel’s offset to avoid rubbing on the frame or fender.
• Keyway: 3/16" wide. Verify your axle key size. If you have a 1/4" keyway, these won’t engage properly.

Check your mower’s model number or existing tire sidewall for exact specs. These are aftermarket replacements, not OEM, so they may differ slightly from factory wheels (e.g., hub shape, valve stem location).

Key Things to Know

• 4-ply rating means decent puncture resistance for typical lawn use, but not for heavy-duty or rocky terrain.
• Tubeless design – no inner tube to replace, but the bead must seat properly on the rim. Use soapy water on the bead during installation if it’s tight.
• Installation is straightforward if your old tires are worn or damaged: remove the cotter pin and axle nut, slide off old assembly, slide on new one, and reinstall hardware. Torque axle nut to 40–50 ft-lbs.
• Common gotcha: The 3/16" keyway may be slightly oversized. If the key wiggles, use a new key or file it to fit snugly. Also check that the wheel hub clears your brake disc or fender bracket.

Should You Buy It

Yes, if you need a direct-fit, budget-friendly replacement for a worn or flat 20x8.00-8 rear tire on a standard riding mower. It’s a solid value for homeowners with common brands like Craftsman, Husqvarna, or MTD. Skip it if you have a non-standard axle size, need a higher ply rating for heavy loads, or require an exact OEM match for a commercial mower.
