- Balancing: Tires must be properly balanced to prevent vibration and ensure even wear.
- Lug Nut Torque: After installation, ensure lug nuts are tightened to the vehicle manufacturer's specified torque settings. Re-check torque after the first 50-100 miles of driving.

3. Maintenance
Regular maintenance is essential for maximizing tire life, ensuring safety, and maintaining vehicle performance.
- Tire Pressure: Check tire pressure monthly, or before long trips, using an accurate tire gauge. Always check when tires are cold. Refer to your vehicle's owner's manual or door jamb placard for recommended pressures.
- Tire Rotation: Rotate tires regularly according to your vehicle manufacturer's recommendations, typically every 5,000 to 8,000 miles. This promotes even wear across all tires.
- Tread Depth: Monitor tread depth using a tread depth gauge. The minimum legal tread depth is 2/32 inch. Replace tires when they reach this limit. This tire has an original tread depth of 13/32nds.
- Visual Inspection: Regularly inspect tires for signs of damage, such as cuts, punctures, bulges, or uneven wear patterns. Address any damage promptly.
- Wheel Alignment: Ensure proper wheel alignment to prevent irregular tire wear. Have alignment checked periodically or if you notice steering issues.

4. Troubleshooting
Addressing common tire issues promptly can prevent further damage and ensure safety.
- Uneven Tread Wear: Can be caused by improper inflation, misalignment, or lack of rotation. Check tire pressure, have alignment inspected, and ensure regular rotation.
- Vibration: Often indicates an unbalanced tire or a bent rim. Have tires re-balanced and wheels inspected by a professional.
- Loss of Air Pressure: May be due to a puncture, valve stem leak, or bead leak. Inspect the tire for damage and have it repaired or replaced by a professional.
- Bulges or Cracks: These are signs of internal damage and can lead to tire failure. Immediately replace any tire exhibiting bulges or significant cracks.
