TRIPOWER 20x10.00-8 Lawn Mower Tire and Wheel Assembly- 20x10x8 Tires and Rims, 3.5" Offset Hub, 3/4" Borehole, 3/16" Keyway, for Lawn Mower Tractor, 4PR Tubeless, 1190 lbs Capacity, Set of 2

What It Is

This is a set of two 20x10.00-8 lawn mower tire and wheel assemblies designed for heavy-duty zero-turn mowers, garden tractors, and large riding mowers. The 4-ply tubeless tires and 3.5-inch offset hub with a 3/4-inch bore and 3/16-inch keyway handle up to 1,190 lbs per pair, making them ideal for rear-wheel replacements on commercial or residential mowers needing extra load capacity and traction.

Fitment & Compatibility

Before buying, verify these four measurements:

• Tire size: 20x10.00-8 (20-inch outer diameter, 10-inch width, 8-inch rim). Not compatible with 20x8-8 or 20x12-8 tires.
• Hub offset: 3.5 inches (center of wheel to mounting face). Measure your current wheel’s offset; mismatched offset affects turning clearance and stability.
• Bore & keyway: 3/4-inch bore with a 3/16-inch keyway. Common on many zero-turn and garden tractor axles, but check if your axle uses a key or a different bore size (e.g., 5/8-inch or 1-inch).
• Bolt pattern: Not specified, so measure your existing wheel’s lug nut spacing. Most zero-turn mowers use a 4-bolt pattern on 4-inch or 4.5-inch centers, but confirm.

Common brand fits: Many John Deere, Cub Cadet, Husqvarna, and Toro zero-turn models, but always cross-reference your model’s OEM part number (e.g., John Deere AM137562 or similar). Not for push mowers or small lawn tractors with 18-inch or smaller rear tires.

Key Things to Know

• Load rating: 1,190 lbs per pair is high—sufficient for heavy mowers with operators, but check your mower’s weight. Overkill for lightweight residential models.
• Installation: Easy if you have a jack and standard tools. The keyway and bore fit snugly; use anti-seize on the axle to prevent corrosion. No tire mounting needed—pre-assembled.
• Quality: 4-ply rating is typical for this price range. Some users report minor balance issues at high speeds; a quick balance with stick-on weights fixes it.
• Gotcha: The 3.5-inch offset may stick out wider than OEM on some mowers, potentially rubbing fenders or deck sides. Measure clearance before ordering.

Should You Buy It

Buy this set if you need heavy-duty rear tires for a zero-turn or garden tractor with a 3/4-inch keyed axle and 3.5-inch offset, especially if you’re replacing worn OEM tires or upgrading from smaller sizes. Skip it if your mower requires a different bore, offset, or bolt pattern—measure first to avoid a return.
