2 NEW HORSESHOE 18x9.50-8 6Ply Turf Trac Pattern for Ridding Lawn Garden Mower Utility Cart Tires Tubeless 18x9.5-8 T198 189508

What It Is

This is a pair of 18x9.50-8 turf-tread tires (6-ply rating) designed for riding lawn mowers, garden tractors, and utility carts. The horseshoe-style tread pattern provides low ground pressure and reduced turf damage, making them ideal for mowing, towing, or light hauling on grass.

Fitment & Compatibility

Before buying, confirm all three measurements:

• Size: 18x9.50-8 (also labeled T198 or 189508). The tire diameter is 18 inches, width 9.50 inches, and it fits an 8-inch rim.
• Rim width: These tires mount on rims 6.0–8.0 inches wide. Check your existing wheel’s rim width (stamped on the rim) – most riding mowers use 7.0-inch wide rims.
• Bolt pattern & offset: This is a tire-only purchase – you reuse your existing wheels. Ensure your wheel’s bolt pattern (e.g., 4x4, 5x4.5) and offset match your machine’s axle. Common on brands like John Deere, Cub Cadet, Husqvarna, Troy-Bilt, and Craftsman.

Also verify load capacity: 6-ply rating (approx. 600–700 lbs per tire at max PSI) – sufficient for most riding mowers and light utility carts, but not for heavy-duty tractors or full-size ATVs.

Key Things to Know

• Installation difficulty: Moderate – you’ll need to separate the old tire from the rim, mount the new one, and reseat the bead. A tire machine or pry bars and a bead seater are recommended. If you’re not comfortable, a local tire shop can do it for ~$20–$30 per tire.
• Tread pattern: The turf-trac (horseshoe) design is excellent for grass – minimal marking – but offers limited traction on mud, loose dirt, or slopes. Not for off-road use.
• Tubeless design: These are tubeless tires, but you can still use a tube if your rim leaks or has a damaged bead seat. Check your rim’s condition before mounting.
• Pressure recommendation: Run at 12–15 PSI for mowing; lower pressure (8–10 PSI) for cart use to soften the ride. Exceeding 20 PSI risks blowout.

Should You Buy It

Buy these if you need a reliable, turf-friendly replacement for a riding mower or garden cart and you’re comfortable mounting tires yourself or paying a shop. Avoid if you need aggressive traction for rough terrain or if your machine requires a different size (e.g., 20x10-8 or 18x8.50-8). For the price, this is a solid value for standard residential use.
