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

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 replace worn or damaged rear tires with a 4-ply tubeless design and a pre-assembled hub for bolt-on installation.

Fitment & Compatibility

Before buying, verify these three measurements:

• Borehole: 3/4" diameter – common on many Craftsman, Husqvarna, John Deere, and MTD models.
• Offset: 3.5" hub offset – measure your existing wheel’s offset (distance from mounting face to wheel center) to ensure clearance.
• Keyway: 3/16" wide – matches most axles with a key slot; check your axle key size.

Also confirm tire size (20x8.00-8) matches your mower’s rear tire spec. This assembly is aftermarket, not OEM, so it fits many brands but may require minor modifications on older or odd-fit models. Measure your current wheel’s bolt pattern and axle diameter to avoid returns.

Key Things to Know

• Quality: 4-ply rating is adequate for residential mowing on flat terrain; not for heavy commercial use or rocky slopes.
• Installation: Moderate difficulty – you’ll need a jack, socket set, and possibly a hammer to seat the keyway. Tires come mounted and inflated, but check pressure before use.
• Common gotchas: The 3.5" offset may rub against the mower frame or deck on some models; measure clearance first. The 3/16" keyway may not fit metric axles (e.g., some older models use 5mm keys).
• Tubeless design: No inner tube needed, but rim must be airtight; inspect for leaks after mounting.

Should You Buy It

If you need a budget-friendly replacement for a worn rear tire on a standard riding mower with a 3/4" axle and 3.5" offset, this set is a solid value. Avoid it if your mower has a non-standard axle size, tight frame clearance, or you need heavy-duty tires for rough terrain.
