Understanding Trailer Wheel Torque Specs for Safe Towing
Ensuring proper lug nut torque is essential for safe towing. Always tighten lug nuts using clean, dry threads. Never lubricate threads.
Recommended Torque Settings for Boat Trailer Wheels:
- Torque Values for Knott Torsion Axles: 63–67 ft-lbs – Trailer Example: 67BT 12-14 1200
- Torque Values for EZ Loader Torsion & Spring Axles: 90–120 ft-lbs – Spring Axle Trailer Example: 90BS 14-18 2300
- Torque Values for UFP Spring Axles: 90–120 ft-lbs
These recommendations align with official EZ Loader manufacturer guidelines.
Lug Nut Wheel Tightening Patterns
Use the correct tightening sequence to evenly distribute pressure:
- 4-Lug Wheels: Crisscross pattern (1-3-2-4)
- 5-Lug Wheels: Star pattern (1-3-5-2-4)
- 6-Lug Wheels: Crisscross pattern (1-4-2-5-3-6)

Essential Maintenance Tips
- Initial Re-Torque: After the first 50 miles of towing, re-check and adjust lug nuts to specified torque.
- Routine Checks: Always verify lug nut torque before each trip.
- Tire Pressure: Regularly maintain recommended tire pressures per tire manufacturer guidelines.
- Wheel Bearings: Frequently inspect and lubricate wheel bearings, especially after water exposure.
