Set of 2-18X9.50-8 4 Ply Reaper Tire

What It Is

This is a pair of 18x9.50-8, 4-ply rated “Reaper” tires designed for zero-turn mowers and garden tractors. The aggressive tread pattern provides extra traction on slopes, wet grass, and loose soil compared to standard turf tires.

Fitment & Compatibility

Measure before you buy: The tire size is 18 inches tall, 9.50 inches wide, and fits an 8-inch rim. Verify your current tire’s sidewall markings match exactly—especially the width and rim diameter.
Rim fit: These are tires only (no rims). They mount on standard 8-inch wheels with a 4-inch bolt pattern (common on brands like Husqvarna, John Deere, and Craftsman zero-turns).
OEM vs aftermarket: Not an OEM part for any specific brand. Works as a direct replacement if your stock tire size is 18x9.50-8. Check your mower’s manual or existing tire sidewall for the exact size.
Load capacity: 4-ply rating means roughly 480 lbs per tire at 20 psi—sufficient for most residential zero-turns and small garden tractors.

Key Things to Know

• Installation: Requires basic tire mounting tools (tire irons, bead seater) or a shop. Not a bolt-on swap unless you have loose rims.
• Tread depth: Aggressive “Reaper” tread is deeper than standard turf tires—excellent for traction but may scuff turf if you turn sharply on delicate lawns.
• Pressure: Recommended at 15-20 psi. Overinflating reduces traction and ride comfort; underinflating risks sidewall damage.
• 4-ply vs 6-ply: 4-ply is lighter and rides softer—fine for residential use. Avoid heavy commercial duty or rocky terrain where 6-ply is safer.

Should You Buy It

Yes, if you need better grip on hills, mud, or loose dirt and your mower uses 18x9.50-8 tires. The 4-ply rating keeps weight and cost low for typical homeowner use. Skip if you mow flat, manicured lawns—standard turf tires will be gentler on grass.
