20x8.00-8 Lawn Mower Tire and Wheel Tubeless with 3/4 Bushing, 3.5"Offset Hub and 3 1/16" Keyway 20x8x8 Lawn Mower Tire with Rim for Tractor Rear, Turf Tread 20 inch Wheels, 800 lbs Weight Capacity

What It Is

This is a complete 20x8.00-8 tubeless turf tire and wheel assembly designed for rear use on lawn tractors, zero-turn mowers, and garden tractors. It features a 3/4-inch bushing, 3.5-inch offset hub, and 3 1/16-inch keyway, with a 800 lb weight capacity for heavy-duty mowing tasks.

Fitment & Compatibility

Before buying, check these specifics:

• Tire size: 20x8.00-8 (fits rims with 8-inch diameter; verify your existing tire sidewall matches).
• Hub offset: 3.5 inches (measure from mounting face to wheel centerline; mismatched offset can cause rubbing or poor tracking).
• Bushing: 3/4-inch bore (fits most standard tractor axles; if your axle is larger or smaller, you’ll need a different bushing or adapter).
• Keyway: 3 1/16-inch keyway (confirm your axle key length and width; some tractors use shorter or metric keys).
• Weight capacity: 800 lbs per tire (sufficient for most residential zero-turns and garden tractors, but check your mower’s rear axle load).
• Brand/model: Not OEM-specific; fits many Craftsman, Husqvarna, John Deere, MTD, and Troy-Bilt models with 20x8-8 rear tires. Measure your current wheel’s bolt pattern and center hole diameter if possible.

Key Things to Know

• Quality concerns: 3.8/5 rating with 105 reviews suggests some users report inconsistent tire bead seating or minor wobble at high speed. Inspect rim trueness before mounting.
• Installation difficulty: Moderate. You’ll need a lug wrench, possibly a keyway file, and may need to swap bushings. No special tools required, but a tire machine helps if bead is tight.
• Common gotcha: The 3.5-inch offset may not match all mowers—measure your current wheel’s offset from the axle flange to the tire centerline. A mismatch can cause tire to rub frame or deck.
• Tubeless design: No tube needed, but rim must be clean and free of rust for proper seal. Use tire sealant if you anticipate leaks.

Should You Buy It

Buy this if you need an affordable, heavy-duty rear tire for a residential lawn tractor or zero-turn with a 3/4-inch axle and 3.5-inch offset. It’s a solid budget option for replacing worn or damaged OEM wheels, but double-check offset and keyway measurements first—fitment isn’t universal. If you need exact OEM match or a smoother ride, consider a higher-rated brand.
