Setup and Installation
Proper installation is crucial for tire performance and safety. It is highly recommended that tire mounting and balancing be performed by a certified professional.
1. Professional Installation
Always have your new HANKOOK Ventus S1 evo3 (K127) tires mounted and balanced by a qualified tire technician. They possess the specialized tools and expertise to ensure correct fitment and balance, which is essential for vehicle handling and tire longevity.
2. Initial Inflation
After installation, ensure tires are inflated to the vehicle manufacturer's recommended pressure, typically found on a sticker inside the driver's side door jamb, glove compartment, or in the vehicle owner's manual. Do not exceed the maximum pressure indicated on the tire sidewall.

Operating Guidelines
1. Tire Pressure Monitoring
Check tire pressure regularly, at least once a month and before long trips, using an accurate tire pressure gauge. Adjust pressure when tires are cold (driven less than a mile). Correct tire pressure is vital for safety, fuel efficiency, and tire wear.
2. Driving Conditions
The HANKOOK Ventus S1 evo3 (K127) is a summer performance tire. It is designed for optimal performance in warm weather conditions and should not be used in freezing temperatures or on snow/ice. Avoid aggressive driving, especially during the break-in period (first 500 miles).
3. Load Capacity
Do not exceed the maximum load capacity specified for your tire and vehicle. Overloading can lead to tire failure, poor handling, and reduced fuel economy.
Maintenance
1. Regular Inspection
Periodically inspect your tires for signs of wear, damage, or foreign objects. Look for uneven tread wear, cuts, bulges, or punctures. If any damage is found, have the tire inspected by a professional immediately.

2. Tire Rotation
Rotate your tires every 5,000 to 7,500 miles, or as recommended by your vehicle manufacturer. Regular rotation helps promote even tread wear, extending tire life and maintaining balanced handling.

3. Cleaning and Storage
Clean tires with mild soap and water. When storing tires not in use, keep them in a cool, dry place away from direct sunlight, heat sources, and chemicals that could degrade the rubber.

Troubleshooting
- Uneven Tread Wear:
Cause: Improper inflation, misalignment, or worn suspension components.
Solution: Check tire pressure, have wheel alignment checked, and inspect suspension system. Rotate tires regularly. - Vibrations:
Cause: Unbalanced tires, bent rim, or worn suspension parts.
Solution: Have tires re-balanced, inspect rims for damage, and check suspension components. - Slow Leak/Puncture:
Cause: Nail, screw, or other sharp object embedded in the tire.
Solution: Do not remove the object. Drive slowly to a tire professional for inspection and repair. Avoid driving on a flat tire.
