3. Installation
Proper installation is crucial for tire performance and safety. It is highly recommended that these tires be installed by a qualified professional.
3.1 Pre-Installation Checks
- Verify that the tire size (235/60R18), load index (103), and speed rating (H) match your vehicle's specifications as recommended by the vehicle manufacturer.
- Inspect the tire for any visible damage or defects prior to mounting.
3.2 Mounting and Balancing
- Ensure rims are clean, free of rust, and undamaged.
- Use appropriate mounting lubricants and tools to prevent damage to the tire bead.
- Always balance tires after mounting to prevent vibrations and ensure even wear.
3.3 Inflation Pressure
- Inflate tires to the pressure recommended by your vehicle manufacturer, typically found on a placard inside the driver's side door jamb, glove compartment, or owner's manual.
- Never exceed the maximum inflation pressure molded on the tire sidewall.

4. Operation
To maximize the lifespan and performance of your Summit Ultramax A/S tires, adhere to the following operational guidelines:
- Regular Pressure Checks: Check tire pressure at least once a month, and before long trips, using an accurate tire gauge. Adjust pressure when tires are cold.
- Driving Conditions: While designed for all-season use, exercise caution in severe winter conditions (heavy snow or ice) as dedicated winter tires may offer superior performance.
- Avoid Overloading: Never exceed your vehicle's maximum load capacity or the tire's maximum load rating. Overloading can lead to tire failure.
- Speed Limits: Adhere to posted speed limits and the tire's speed rating (H). Excessive speed can generate heat, leading to tire damage or failure.
5. Maintenance
Consistent maintenance helps ensure safety and extends tire life.
- Tire Rotation: Rotate your 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.
- Tread Depth Monitoring: Regularly check tread depth. Tires should be replaced when tread depth reaches 2/32nds of an inch (1.6 mm).
- Visual Inspection: Inspect tires regularly for cuts, punctures, bulges, or other damage. Any damage should be inspected by a tire professional immediately.
6. Troubleshooting
If you experience any of the following issues, consult a qualified tire professional:
- Uneven Tire Wear: Can indicate improper inflation, misalignment, or balancing issues.
- Vibration: Often a sign of unbalanced tires or a bent rim.
- Loss of Air Pressure: Could be due to a puncture, valve stem issue, or bead leak.
- Steering Pull: May suggest an alignment problem.
Do not attempt to repair damaged tires yourself. Always seek professional assistance.
