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

What It Is

This is a pair of 20x8.00-8 tubeless lawn mower tires mounted on wheels with a 3.5" offset hub, a 3/4" borehole, and a 3/16" keyway. Designed for riding mowers, zero-turn mowers, and garden tractors needing a durable, 4-ply replacement for drive or front steer wheels.

Fitment & Compatibility

Before buying, verify these four measurements:

• Tire size: 20x8.00-8 (20" diameter, 8" wide, fits 8" rim). Common on many John Deere, Husqvarna, Craftsman, and Troy-Bilt models. Measure your old tire’s sidewall markings.
• Borehole: 3/4" (0.75") – must match your axle diameter. Larger axles require a different hub.
• Keyway: 3/16" – needed if your axle uses a key to lock the wheel. If your machine uses a keyed axle, this matches. If not, the keyway is unused but won’t interfere.
• Offset: 3.5" – distance from hub mounting face to wheel centerline. Check your old wheel’s offset by measuring from the mounting surface to the outside edge of the rim. Wrong offset can cause rubbing on the mower deck or frame.

Not compatible with standard push mowers (smaller wheels) or zero-turns with 5/8" or 1" axles.

Key Things to Know

• 4-ply rating – good for residential use, handles up to ~590 lbs per tire. Not for heavy commercial decks or rocky terrain.
• Tubeless design – no inner tube needed, but ensure the bead seats fully on the rim to avoid slow leaks. Use a tire sealant if mounting yourself.
• Installation – moderate difficulty. You’ll need a jack, socket set, and possibly a pry bar for stubborn old tires. The keyway slot may need slight filing if tight.
• Common gotcha – the 3.5" offset may differ from OEM wheels on some older tractors. Always compare offset before ordering to avoid clearance issues.

Should You Buy It

Yes, if you need a reliable, budget-friendly replacement for a riding mower with a 20x8-8 tire, 3/4" axle, and 3/16" keyway. The 4-ply tubeless design works for most residential yards, and the 4.7-star rating indicates few fitment surprises. Avoid if your machine uses a non-standard bore, offset, or requires a 6-ply tire for heavy loads.
