Buying Guide: Key Considerations For 18×8.5-8 Turf Tires
- Load capacity: Most 18×8.50-8 tires support about 815 lbs at 22 psi. Ensure the tires meet or exceed the gross load of your equipment.
- Tread design: Turf-friendly P332 patterns minimize lawn damage and reduce turf wear; consider tread depth around 4 mm for balanced traction and lawn preservation.
- Construction: 4PR tires offer sturdier sidewalls and better puncture resistance for uneven lawns; tubeless designs are common for ease of maintenance.
- Rim compatibility: Common rim size is 8″ diameter with 7″ width; confirm your mower’s wheel width and lug pattern (PCD) before purchase.
- Vehicle compatibility: While most 18×8.50-8 tires fit a broad range of mowers, confirm fit for zero-turns, riding mowers, golf carts, and garden tractors, especially hub and axle differences.
- Non-highway use: Many options are intended for yard work rather than street driving; plan usage accordingly.
- Replacement strategy: If replacing two tires, match tread type and load specs on both sides to avoid uneven handling.
