Lawn/Garden Tire, 18x9.5-8, 2 Ply, Turf

What It Is

This is a replacement turf tire sized 18x9.5-8 (18" diameter, 9.5" width, 8" rim) with a 2-ply rating, designed for zero-turn mowers, riding lawn tractors, and garden tractors that require low ground pressure and minimal turf damage.

Fitment & Compatibility

Before buying, verify three things:

• Rim size: This tire fits an 8-inch diameter rim only. Measure your existing rim or check your mower manual.
• Load rating: 2-ply is for light-duty residential use. If your machine is heavy (e.g., a large zero-turn with a full hopper), you may need a 4-ply or 6-ply tire.
• Bolt pattern & offset: The tire itself fits any 8" rim, but your rim’s bolt pattern (e.g., 4 on 4, 5 on 4.5) and offset must match your mower’s axle. This is a tire only—no rim included.
• Common fit: Works on many Craftsman, Husqvarna, John Deere, Troy-Bilt, and Ariens models. Always cross-reference your OEM part number (e.g., 590-06285, 490-501-0032) with this tire’s specs.

Key Things to Know

• Turf-friendly tread: The ribbed design is smooth and won’t tear up lawns, but it offers minimal traction on slopes or wet grass. Not for muddy or rough terrain.
• Installation: Mounting requires basic tire tools (tire irons, bead breaker) and a compressor to seat the bead. If you’re not comfortable, a shop will charge ~$15–$25 per tire.
• Tread life: 2-ply tires wear faster on paved surfaces or under heavy loads. Expect 1–3 seasons of residential use.
• Common gotcha: The “18x9.5-8” size can vary slightly between brands. Measure your old tire’s diameter—some “18” tires measure closer to 17.5”. This tire is true to size.

Should You Buy It

Buy this if you need a direct replacement for a worn 18x9.5-8 turf tire on a residential riding mower or garden tractor, and you mow flat, well-maintained lawns. Skip it if you need a higher load capacity, better traction on hills, or a tire for heavy commercial use—upgrade to a 4-ply or a more aggressive tread.
