2. Safety Information
Always prioritize safety when handling and operating with tires. Improper tire use or maintenance can lead to serious accidents. Consult a qualified tire professional for all installation and repair services.
- Tire Pressure: Maintain correct tire inflation pressure as specified by your vehicle manufacturer. Check pressure regularly, at least once a month and before long trips, using an accurate gauge.
- Load Capacity: Do not exceed the maximum load capacity indicated on the tire sidewall and in your vehicle's owner's manual. Overloading can cause tire failure.
- Speed Rating: Adhere to the tire's speed rating. Exceeding this speed can lead to tire damage or failure.
- Tire Inspection: Regularly inspect tires for cuts, punctures, bulges, or uneven wear. Any damage should be addressed immediately by a professional.
- Tread Depth: Replace tires when tread depth reaches the minimum legal limit (typically 2/32 inch or 1.6 mm).
3. Installation
Tire installation should always be performed by trained professionals using appropriate equipment. Incorrect installation can lead to tire damage, wheel damage, or unsafe driving conditions.
- Mounting: Ensure tires are mounted on approved rims that match the tire size. Use proper lubrication and mounting techniques to prevent bead damage.
- Balancing: After mounting, tires must be properly balanced to prevent vibrations and ensure even wear.
- Valve Stems: Always install new valve stems when replacing tires to ensure a proper seal and prevent air loss.
- Torque: Wheel nuts must be tightened to the vehicle manufacturer's specified torque settings. Re-check torque after the first 50-100 miles of driving.
4. Operating Guidelines
The Hankook DynaPro HT RH12 tire is engineered for a premium highway driving experience across various seasonal conditions.
- All-Season Performance: The wide tread design provides ample grip in diverse seasonal conditions, including wet and light snow.
- Snow Traction: Features are designed to enhance snow traction, making it suitable for winter driving where conditions are not severe.
- Steering Response: A highly stiff center block contributes to exceptional and responsive steering on both wet and dry surfaces.
- Reduced Road Noise: The computer-generated tread design helps to minimize road noise for a quieter ride.
- Hydroplane Prevention: Four circumferential grooves effectively assist in expelling water from beneath the tire, reducing the risk of hydroplaning.

5. Maintenance
Regular maintenance is crucial for maximizing tire life and ensuring safe operation.
- Tire Rotation: Rotate tires every 5,000 to 7,500 miles, or as recommended by your vehicle manufacturer, to promote even wear.
- Wheel Alignment: Have your vehicle's wheel alignment checked periodically, especially if you notice uneven tire wear or steering issues.
- Tire Cleaning: Clean tires with mild soap and water. Avoid harsh chemicals that can degrade rubber.

6. Troubleshooting
If you encounter any of the following issues, consult a tire professional immediately:
- Vibration: Persistent vibration at certain speeds may indicate an unbalanced tire, bent rim, or alignment issue.
- Uneven Wear: Irregular wear patterns (e.g., shoulder wear, center wear, feathering) often point to incorrect inflation, misalignment, or suspension problems.
- Loss of Pressure: Frequent or rapid loss of air pressure can be due to a puncture, faulty valve stem, or bead leak.
- Bulges or Cracks: Any visible bulges, cracks, or separations on the tire sidewall or tread indicate internal damage and require immediate replacement.
