WANDA Lawn Mower Tractor Tire Wheel Assembly 20X8-8 4-Ply P512 with 3/4" Bushing 3/16" Keyway 3-1/2" offset Hub Silver Wheel-13131,SET 2

What It Is

This is a set of two 20x8-8 lawn tractor rear tires pre-mounted on silver steel wheels with a 4-ply rating, designed for heavy-duty mowing and garden tractors needing a 3/4" axle with a 3/16" keyway and 3-1/2" offset hub.

Fitment & Compatibility

Before buying, verify these four measurements on your tractor:

• Axle diameter: Must be 3/4" (common on larger riders and garden tractors).
• Keyway: Requires a 3/16" key slot in the axle; if your axle has no keyway or a different size, this wheel won’t lock on.
• Offset: Hub is offset 3-1/2" – measure from mounting face to wheel centerline. Too much or too little offset can cause tire rub on the fender or frame.
• Tire size: 20x8-8 (20" tall, 8" wide, fits 8" rim). Check clearance under your mower deck and between frame rails.

This is an aftermarket replacement, not OEM-specific. It commonly fits brands like Husqvarna, Craftsman, MTD, John Deere, and Ariens with the above specs, but always measure your existing wheel’s offset and axle type. The 4-ply rating handles up to ~480 lbs per tire, so it’s fine for most residential and light commercial mowers.

Key Things to Know

• Installation is straightforward if your axle is 3/4" with a 3/16" keyway – just slide on, align key, and secure with a cotter pin or clip. No hub adapters or special tools needed.
• Valve stem location is on the inside of the wheel – you may need to rotate the wheel to access it for inflation after mounting.
• 4-ply vs 6-ply: This tire is rated for light to medium loads. If you have a heavy zero-turn or carry attachments, consider a 6-ply for extra puncture resistance.
• Keyway bushing included: The 3/4" bushing is pre-installed; the 3/16" keyway is machined into it. Double-check that your axle key matches this width.

Should You Buy It

Buy this set if your tractor has a 3/4" axle with a 3/16" keyway and you need a reliable, no-hassle replacement for worn or damaged rear tires. It’s a good value for the price, with solid 4-ply durability for most lawn care tasks. Avoid if your axle size or offset differs, or if you need a higher ply rating for heavy commercial use.
