18x8.50-8 Lawn Mower Tires with Rim,18x8.5x8" Tubeless Tractor Tires, 2-Pack Tire and Wheel Assembly,4 Ply for Riding Mowers Lawn Tractors Golf Cart Turf Tires

What It Is

This is a 2-pack of 18x8.50-8 tubeless tire and wheel assemblies, designed for riding mowers, lawn tractors, and golf carts. The 4-ply rating provides durability for turf use without damaging grass.

Fitment & Compatibility

Before buying, confirm three things:

• Tire size: Must be 18x8.50-8 (18" diameter, 8.50" width, 8" rim). Measure your current tire sidewall if unsure.
• Bolt pattern & hub size: Measure the center hole diameter and lug pattern (typically 4 on 4" or 4 on 5.5" for tractors). This assembly uses a standard 3/4" bushing, but verify your axle shaft diameter.
• Deck clearance: Ensure the 18" tire doesn’t rub against your mower deck or frame, especially on older or compact models. Check by turning the steering full lock and measuring clearance.

Commonly fits John Deere, Craftsman, Husqvarna, and MTD models, but always cross-reference your OEM part number (e.g., AM125907, 590-06208). Aftermarket tires may vary slightly in tread depth or rim offset.

Key Things to Know

• Installation: Usually bolt-on, but you may need to swap the existing pulley or hub if the new rim’s center hole is too large or small. Check for included bushings or adapters.
• Tread pattern: These are turf tires (smooth or shallow tread). They provide good traction on grass but slip on wet pavement or loose dirt. Not for heavy mud or snow.
• Load rating: 4-ply is adequate for standard riding mowers (up to ~500 lbs per tire). Heavier zero-turn mowers or carts carrying loads may need 6-ply.
• Air pressure: Run at 12-15 psi for most lawns. Overinflating reduces traction and can cause a harsh ride; underinflating risks rim damage.

Should You Buy It

If you need a direct replacement for worn or damaged 18x8.50-8 tires on a residential riding mower or lawn tractor, this 2-pack offers good value at $88.99. It’s ideal for turf use, easy to install if your bolt pattern matches, and the 4-ply is sufficient for typical mowing duty. Skip it if you require a different tire size, need a higher load rating, or are replacing drive tires on a zero-turn (which often use wider 20x10-8 or 22x11-10).
