GICOOL 20x10.00-8 Lawn Mower Tire and Wheel, 3/4" Borehole, and 3/16" Keyway, 3.5" Offset Hub, 4 Ply Tubeless Tire, Replacement 20x10-8nhs Riding Lawn Mower and Tractor Rear Tire and Wheel Assemblies

What It Is

The GICOOL 20x10.00-8 tire and wheel assembly is a direct replacement rear tire for riding mowers and lawn tractors, designed to handle heavy loads and uneven terrain. It’s commonly used on zero-turn mowers, garden tractors, and utility vehicles requiring a wide, stable footprint.

Fitment & Compatibility

Before buying, confirm these four measurements:

• Tire size: 20x10.00-8 (20" outer diameter, 10" wide, fits 8" rim). This matches standard 20x10-8 NHS (Not for Highway Service) tires.
• Borehole: 3/4" diameter – must match your axle shaft size. Measure your axle end with a caliper.
• Keyway: 3/16" – verify your axle key is the same width. If your mower uses a different key (e.g., 1/4"), this wheel won’t lock properly.
• Hub offset: 3.5" – measure from hub mounting face to wheel centerline. This offset is common on many Craftsman, Husqvarna, John Deere, and MTD models, but not universal. Check clearance to your mower frame and deck.

Pro tip: Remove one existing wheel and measure bore, keyway, and offset before ordering. OEM part numbers vary, but this tire fits many aftermarket applications.

Key Things to Know

• 4-ply rating: Good for residential use (up to ~300 lbs per tire), but not for commercial or heavy-duty work. Sidewalls are stiff enough for normal mowing, not for rocks or stumps.
• Installation: Slips onto axle if bore and keyway match. No special tools needed, but you may need a hammer to seat the key. Lug nuts not included – reuse your originals.
• Tube vs. tubeless: This is tubeless, but if your rim has a slow leak, installing a tube is easy (use a 20x8.00-8 tube). Check rim bead seal before mounting.
• Common gotcha: The 3.5" offset can cause tire rub on some mowers with narrow rear fenders or tight deck clearance. Measure your old wheel offset precisely.

Should You Buy It

Buy this if you need a reliable, budget-friendly replacement for a worn rear tire on a residential riding mower and your axle measures 3/4" with a 3/16" keyway. It’s not for heavy commercial use or oddball offsets, but for standard lawn tractors, it’s a solid value with strong reviews.
