Set of Four 18x8.50-8 4 Ply Turf Tire for Golf Cart or Lawn Mower (4) 18x8.5-8

What It Is

This is a set of four 18x8.50-8 4-ply turf tires designed for lawn mowers, garden tractors, and golf carts. They provide low ground pressure and a smooth ride on turf, making them ideal for mowing, light hauling, or recreational use on grass and hard-packed surfaces.

Fitment & Compatibility

Before buying, measure your current tire size (18x8.50-8) and confirm the rim diameter is exactly 8 inches. These tires fit most standard 8-inch rims with a 4-bolt or 5-bolt pattern, but verify your wheel offset and bolt pattern (common patterns: 4x4, 4x100mm, or 5x4.5 inches). Check your mower or cart’s load rating—these are 4-ply rated for up to ~200 lbs per tire. OEM replacements are fine, but aftermarket rims may need different valve stems or lug nuts. Avoid using on zero-turn mowers with aggressive offset or heavy-duty commercial mowers requiring 6-ply or higher.

Key Things to Know

• Quality: 4-ply rating offers decent puncture resistance for residential use, but not for heavy debris or rocky terrain. Expect a smooth, quiet ride on grass.
• Installation: Easy if you have basic tools (socket wrench, tire irons). Tires come pre-filled with air; you may need to balance or add valve stem cores. No specialized skills required.
• Common Gotchas: These tires are slightly narrower than some OEM options—measure clearance around fenders and steering components. They may not be pre-mounted on rims; check the listing. Also, 18x8.50-8 is a standard size, but actual diameter can vary by brand by 0.5 inches—verify fit with your deck or frame.
• Durability: Expect 2-4 seasons on a residential mower with proper inflation (12-18 PSI). Under-inflation causes sidewall wear.

Should You Buy It

Buy these if you need a budget-friendly, reliable set of turf tires for a residential lawn mower, garden tractor, or golf cart on flat, well-maintained grass. They’re a solid value for light-duty use, but skip them if you need heavy-duty puncture resistance, off-road traction, or exact OEM dimensions for a tight-fit mower deck.
