4. Persediaan dan Pemasangan
Proper installation is critical for the safety and performance of your trailer tires. It is highly recommended that tire mounting and balancing be performed by a qualified tire professional using appropriate equipment.
4.1 Pemeriksaan Pra-Pemasangan
- Periksa Tayar: Before mounting, visually inspect the tire for any manufacturing defects or damage incurred during shipping.
- Verify Rim Compatibility: Ensure the rim size and type are compatible with the ST235/80R16 tire. The rim width must be within the tire manufacturer's recommended range.
- Check Valve Stems: Always install new valve stems when mounting new tires to prevent air leaks.
4.2 Pemasangan dan Pengimbangan
- Clean the rim bead seats thoroughly to ensure a proper seal.
- Lincirkan manik tayar dan bebibir rim dengan pelincir pelekap tayar yang diluluskan.
- Mount the tire onto the rim using a tire mounting machine, ensuring the tire beads are not damaged.
- Inflate the tire slowly to the recommended seating pressure, ensuring both beads seat properly. Do not exceed 40 psi (2.75 bar) to seat beads unless specified otherwise by the tire manufacturer.
- Balance the tire and wheel assembly using a dynamic wheel balancer to prevent vibrations and ensure even wear.
4.3 Wheel Installation and Torque
- Place the mounted tire and wheel assembly onto the trailer hub.
- Install lug nuts and hand-tighten them.
- 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.
- After the first 50-100 miles of towing, re-check the lug nut torque to ensure they remain properly tightened.
5. Garis Panduan Operasi
Adhering to proper operating guidelines will maximize tire life and ensure safe towing.
5.1 Tire Inflation Pressure
- 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 Kapasiti Muatan
- 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.
6. Penyelenggaraan
Penyelenggaraan yang kerap memanjangkan jangka hayat tayar anda dan memastikan operasi yang selamat.
6.1 Pemeriksaan Berkala

- Kedalaman Tapak: Check tread depth regularly. Replace tires when tread depth reaches 2/32 inch (1.6 mm) or when wear indicators are visible.
- Sidewall Condition: Look for signs of weathering, cracking, or damage to the sidewalls.
6.2 Tire Rotation
- Trailer tires can benefit from rotation to promote even wear, especially on multi-axle trailers. Consult a tire professional for recommended rotation patterns and intervals.
6.3 Penyimpanan
