GICOOL 20x8.00-8 Lawn Mower Tire and Wheel, 4 Ply Tubeless Tire, 20x8-8nhs Riding Lawn Mower and Tractor Rear Tire and Wheel Assemblies, 3.5" Offset Hub, 3/4" Borehole, and 3/16" Keyway

What It Is

This is a complete rear tire and wheel assembly for riding lawn mowers and garden tractors, designed to replace worn or damaged rear tires without needing to mount a new tire onto an old rim. It is best suited for residential and semi-commercial mowing on flat to moderately uneven terrain.

Fitment & Compatibility

Before buying, verify these four measurements:

• Tire size: 20x8.00-8 (20" outer diameter, 8" wide, fits an 8" rim). This is a common size for many riding mowers and tractors.
• Hub offset: 3.5" offset. Measure your current wheel’s offset from the mounting surface to the center of the rim. A mismatch can cause rubbing or poor tracking.
• Borehole: 3/4" diameter axle hole. Confirm your mower’s axle diameter is exactly 3/4".
• Keyway: 3/16" keyway (the slot in the bore for the axle key). Check that your axle key matches this width.

This assembly is aftermarket, not OEM. It fits many brands (e.g., John Deere, Craftsman, Husqvarna, MTD, Troy-Bilt) but always measure your existing wheel—model numbers alone aren’t reliable. The 4‑ply rating means it’s not for heavy commercial use or rough, rocky terrain.

Key Things to Know

• Quality: 4‑ply tubeless tire is adequate for mowing lawns but not for heavy loads or aggressive off-road use. Expect a standard tread pattern—no aggressive traction.
• Installation difficulty: Easy. Remove the old wheel, slide this one onto the axle, align the keyway with the axle key, tighten the axle nut to spec (typically 40–60 ft‑lbs). No tire mounting required.
• Common gotchas: The 3/4" borehole is standard, but some older mowers use 5/8" or 1" axles—measure first. Also, the 3.5" offset may not match zero‑turn mowers or tight‑clearance decks; measure clearance to the mower frame and deck.
• Tubeless: No inner tube means fewer punctures, but the tire must seal perfectly to the rim—inspect the bead upon installation.

Should You Buy It

If you need a straightforward, affordable replacement for a worn rear tire on a standard riding mower and your axle and offset match exactly, this is a solid value. It’s not for heavy‑duty or commercial use, and it won’t transform traction on steep slopes or mud. For casual lawn mowing on flat ground, it’s a reliable, easy swap.
