TUFFIOM 20x8.00-8 Lawn Mower Tires and Wheel 2 Pack, 4PR Tubeless Riding Lawn Garden Tractor Mower Tire -3.5" Offset Hub, 3/4" Bore Size & 3/16" Keyway Tire & Wheel Assemblies,965 lbs Load Capacity

What It Is

This is a set of two 20x8.00-8 tubeless lawn mower tires mounted on 3.5-inch offset steel wheels with a 3/4-inch bore and 3/16-inch keyway. Designed for riding mowers, garden tractors, and zero-turn mowers, it supports up to 965 lbs per pair—suitable for heavy-duty mowing, towing, or uneven terrain.

Fitment & Compatibility

Before buying, verify these four measurements:

• Tire size: 20x8.00-8 (20-inch outer diameter, 8-inch width, 8-inch rim). Measure your current tire’s sidewall—this is a common size for rear wheels on many Craftsman, Husqvarna, John Deere, and MTD models.
• Bore size: 3/4 inch. Check your axle diameter—if it’s 5/8 or 1 inch, these won’t fit.
• Keyway: 3/16 inch. The axle key must match; if your axle uses a different key size (e.g., 1/4 inch), you’ll need to modify or buy a different wheel.
• Offset: 3.5 inches (center of wheel to mounting surface). Measure your current wheel’s offset—too much or too little can cause tire rubbing on the mower deck or frame. Compare to OEM part numbers like 590-06279, 590-07070, or 490-501-M062.

Key Things to Know

• Quality concerns: With only 3 reviews and a 3.5-star rating, some users report uneven tread wear or valve stem leaks. Inspect immediately upon arrival.
• Installation: Bolts on directly if fitment matches—no special tools needed. But the keyway alignment may require a hammer or file if tight.
• Load capacity: 965 lbs total is generous for most residential mowers, but check your mower’s weight plus any attachments (e.g., bagger, trailer) to avoid overloading.
• Tubeless design: No inner tube to replace, but the rim bead may be tricky to seat without a compressor. Use a ratchet strap or tire lubricant if needed.

Should You Buy It

Buy these if you need a budget-friendly, direct-replacement set for a common 20x8.00-8 rear tire on a riding mower with a 3/4-inch axle and 3/16-inch keyway—and you’re comfortable with potential minor quality issues. Skip them if your fitment is off (especially offset or bore size) or if you want premium, long-life tires from a brand with more reviews.
