20x8.00-8 Lawn Mower Tire with Keyway 3/4" Bushing Rim, 20x8.00-8 Tubeless Tire and Wheel Assemblies Turf Tread for Rear Riding Lawnmower Garden Tractor, 20 inch Wheels, 800 lbs Capacity

What It Is

This is a 20x8.00-8 rear tire and wheel assembly designed for riding lawn mowers and garden tractors. It features a turf-tread pattern for minimal lawn damage and an integrated 3/4" bushing rim with a keyway for secure axle mounting.

Fitment & Compatibility

Critical measurements:

• Tire size: 20x8.00-8 (20" outer diameter, 8" wide, fits 8" rim)
• Rim center hole: Must accept a 3/4" bushing (check your axle shaft diameter—likely 3/4" or 5/8")
• Keyway: Confirm your axle has a key slot (not all mowers do)
• Bolt pattern: 4-bolt hub, typically 4" on center (measure your old rim)

What to verify before buying:

• Measure your existing tire diameter and width (not just the sidewall numbers)
• Check axle shaft diameter and keyway presence
• Confirm offset/backspacing (this is a standard zero-offset rim, but measure your old wheel’s hub face to rim edge)
• Not for zero-turn mowers or machines with 5/8" axles unless you swap bushings

Key Things to Know

• Load capacity: Rated 800 lbs per tire—fine for most residential garden tractors but not heavy commercial use.
• Installation: Requires basic tools (socket set, torque wrench). The keyway bushing may need slight filing to fit snugly.
• Common gotcha: The 3/4" bushing is fixed; if your axle is smaller (e.g., 5/8"), you’ll need a bushing adapter (sold separately).
• Quality: Turf tread is shallow—good for grass, poor on loose soil or slopes.

Should You Buy It

Buy this if you need a direct replacement for a worn rear tire on a standard riding mower or garden tractor with a 3/4" keyed axle and 4-bolt pattern. It’s a solid value for the price, but skip it if your axle diameter or bolt pattern differs—verifying fitment before ordering will save you a return headache.
