(Set of 2) 18x9.50-8 Turf Tires ATW-003

What It Is

This is a pair of 18x9.50-8 turf tires (model ATW-003) designed for lawn tractors, zero-turn mowers, and garden tractors that require low ground pressure, minimal turf damage, and stable traction on flat or slightly sloped lawns.

Fitment & Compatibility

Before buying, verify these three things:

• Tire size: 18x9.50-8 (18" outer diameter, 9.50" section width, fits an 8" rim). Measure your existing tire sidewall – if it says something like 18x8.50-8 or 18x10-8, these will still mount but may affect ride height or clearance.
• Rim width: These tires are designed for 7" to 8" wide rims. Check your rim’s stamped width (e.g., 7.00-8 or 8.00-8). If your rim is narrower than 6" or wider than 9", these won’t seat properly.
• Load capacity & ply rating: These are likely 4-ply rated (check product listing for exact ply). They’re fine for residential zero-turns and lawn tractors under 600 lbs per tire. Not for heavy commercial mowers or rough terrain.

OEM vs aftermarket: These are aftermarket replacements. They fit most brands (Cub Cadet, John Deere, Husqvarna, Toro, etc.) as long as the size matches. No special adapter or hub kit needed – they mount directly to your existing rims.

Key Things to Know

• Installation: Moderate difficulty. You’ll need a tire bead breaker, rim tool, and air compressor. If you’re not comfortable changing tires yourself, budget $20–$40 per tire at a local shop.
• Turf performance: The ATW-003 tread pattern is a shallow, wide rib design – great for flat lawns, poor for hills or wet grass. If you mow slopes, look for a deeper tread.
• Durability: 4-ply rating is adequate for residential use but not for rocky or debris-heavy yards. Expect 2–4 seasons of regular use.
• Common gotcha: These tires are bias-ply, not radial. They may feel slightly stiffer and less forgiving on bumps than radials. Also, check your tire pressure (recommended 12–15 PSI) – overinflating causes center wear.

Should You Buy It

Buy these if you need a budget-friendly, turf-safe replacement for a residential lawn tractor or zero-turn on flat, well-maintained grass. Skip them if you mow hills, need heavy-duty puncture resistance, or have a commercial mower – you’ll want a higher ply rating or deeper tread.
