YITAMOTOR 20x8.00-8 Lawn Mower Tires & Wheel Assemblies, 4 Ply Tubeless Front Tires Replacement Fits Lawn Tractors, More Riding Mowers & Garden Vehicle | 3/4" Bore Hole, 3/16" Keyway, 960LBS (2 Pack)

What It Is

This is a set of two pre-assembled front wheel-and-tire units (20x8.00-8) for lawn tractors, riding mowers, and garden vehicles. Each assembly includes a 4-ply tubeless tire mounted on a steel rim with a 3/4" bore and 3/16" keyway, rated for up to 960 lbs per pair.

Fitment & Compatibility

Before buying, confirm these three measurements fit your mower:

• Tire size: 20x8.00-8 (20" diameter, 8" wide, fits 8" rim). Common on many John Deere, Cub Cadet, Husqvarna, and Craftsman front axles.
• Bore diameter: Must be 3/4" (0.75"). If your axle is larger or smaller, these won’t mount without a bushing.
• Keyway: 3/16" wide. If your axle uses a different key size or no keyway, you’ll need to modify or swap the axle pin.

Also check:

• Wheel offset/backspacing – measure from mounting face to inner rim edge. These have a standard offset for most lawn tractors, but deep-dish or tight-clearance decks may rub.
• Lug pattern – these use a single center hole with a keyway, not a multi-lug pattern. Verify your spindle accepts a single-bore design.

Key Things to Know

• Assembly included: Tires come already mounted and inflated on rims, no extra tools or tire irons needed.
• Load capacity: 960 lbs per pair is fine for most residential tractors, but check if your machine’s front axle weight exceeds that (unlikely unless you have a heavy front attachment).
• Installation difficulty: Easy – remove old wheel, slide new one on, secure with axle pin or cotter. No tire balancing required for mower use.
• Common gotcha: The 4-ply rating means stiffer sidewalls than 2-ply. This improves puncture resistance but can make the ride slightly harsher on bumpy terrain.

Should You Buy It

If you need a drop-in replacement for a 20x8.00-8 front tire with a 3/4" bore and 3/16" keyway, this is a solid value. It’s best for homeowners who want a quick, no-hassle swap without hunting down separate rims and tires. Not ideal if your axle bore or keyway differs, or if you need a softer 2-ply ride for delicate turf.
