  3. Using a torque wrench, tighten the lug nuts in a star pattern to the trailer manufacturer's specified torque values. Refer to your trailer's owner's manual for correct torque specifications.
  4. After the first 50-100 miles of towing, re-check the lug nut torque to ensure they remain properly tightened.

5. Pautas de funcionamiento

Adhering to proper operating guidelines will maximize tire life and ensure safe towing.

5.1 Presión de inflado de los neumáticos

  • Maintain the recommended cold inflation pressure as indicated on the tire sidewall or your trailer's placard. For ST tires, this is typically the maximum pressure listed on the sidewall.
  • Check tire pressure before each trip and when the tires are cold (have not been driven for at least three hours).
  • Under-inflation can lead to excessive heat buildup, tire damage, and premature wear. Over-inflation can reduce traction and make the tire more susceptible to impact damage.

5.2 Capacidad de carga

  • Never exceed the maximum load capacity specified on the tire sidewall or the trailer's Gross Vehicle Weight Rating (GVWR).
  • Distribute the load evenly on the trailer to prevent uneven tire wear and maintain stability.

5.3 Speed Rating

  • The Triangle TR643 has a speed rating of 'N', which corresponds to a maximum speed of 87 mph (140 km/h).
  • It is recommended to operate trailer tires at speeds no greater than 65 mph (105 km/h) for optimal safety and tire longevity, especially when towing heavy loads or in hot weather.
