2. Installation

Proper installation is critical for tire safety and performance. It is highly recommended that installation be performed by a qualified tire professional using appropriate equipment.

2.1 Pre-Installation Checks

• Ensure the tire size and load/speed ratings match your vehicle's requirements as specified in your vehicle owner's manual.
• Inspect the tire for any visible damage or manufacturing defects prior to mounting.
• Verify that the wheel rim is clean, free of damage, and compatible with the tire size.

2.2 Mounting and Balancing

• Mount the tire onto the wheel using proper tire mounting equipment to avoid damage to the tire beads or rim.
• Balance the tire and wheel assembly to prevent vibrations and ensure even tread wear.

2.3 Inflation

• Inflate the tire to the pressure recommended by your vehicle manufacturer, typically found on a placard inside the driver's side door jamb, glove compartment, or fuel filler flap. Do not exceed the maximum pressure molded on the tire sidewall.
• Use a reliable pressure gauge to ensure accurate inflation.

2.4 Lug Nut Torque

• Tighten lug nuts to the vehicle manufacturer's specified torque settings using a torque wrench.
• Re-check lug nut torque after the first 50-100 miles of driving.

3. Operating Guidelines

Adhering to these guidelines will help ensure safe operation and maximize the lifespan of your tires.

3.1 Tire Pressure

• Maintain correct tire pressure as specified by your vehicle manufacturer. Check pressure at least once a month, and before long trips, when tires are cold.
• Under-inflation can lead to excessive heat buildup, tire damage, and reduced fuel efficiency. Over-inflation can result in a harsh ride, reduced traction, and premature wear in the center of the tread.

3.2 Load Capacity and Speed Rating

• The Hankook Dynapro MT (RT03) LT33X12.50R20 114Q E has a load capacity of 1477 pounds per tire and a speed rating of 'Q'.
• Do not exceed the maximum load capacity or speed rating of the tire. Overloading or exceeding the speed rating can lead to tire failure.

3.3 Off-Road Use

• This tire is designed for excellent traction in mud, snow, and sand. Its large voids and ejectors help maintain grip by clearing debris.
• When driving off-road, adjust tire pressure as appropriate for the terrain, but always re-inflate to vehicle manufacturer specifications before returning to paved roads.
• Exercise caution and reduce speed when driving on rough or uneven terrain to prevent tire damage.

4. Maintenance

Regular maintenance extends tire life and ensures optimal performance.

4.1 Regular Inspections

• Visually inspect tires regularly for cuts, punctures, bulges, or uneven wear.
• Check tread depth. The original tread depth is approximately 9/32nds. Replace tires when tread depth reaches 2/32nds of an inch, indicated by tread wear indicators.

4.2 Tire Rotation

• Rotate tires every 5,000 to 7,500 miles, or as recommended by your vehicle manufacturer, to promote even wear across all four tires.

4.3 Wheel Alignment and Balancing

• Have your vehicle's wheel alignment checked periodically, especially after hitting potholes or curbs, to prevent uneven tire wear.
• Re-balance tires if you notice vibrations or after any tire repair.

4.4 Cleaning and Storage

• The Dynapro MT (RT03) features a self-cleaning tread design. However, after severe off-road use, rinse tires to remove excessive mud or debris.
• When storing tires, keep them in a cool, dry place away from direct sunlight, heat sources, and chemicals.

5. Troubleshooting

This section addresses common tire-related issues.

5.1 Uneven Tread Wear

• Cause: Incorrect tire pressure, improper wheel alignment, or lack of tire rotation.
• Solution: Check and adjust tire pressure, have alignment inspected, and follow recommended tire rotation schedule.

5.2 Vehicle Vibration

• Cause: Unbalanced wheels, damaged tire, or suspension issues.
• Solution: Have tires re-balanced. Inspect tires for damage. If vibration persists, consult a mechanic for suspension inspection.

5.3 Loss of Air Pressure

• Cause: Puncture, leaky valve stem, or damaged rim.
• Solution: Inspect the tire for punctures. Check valve stem for leaks. If a puncture is found, have the tire professionally repaired or replaced.

For any persistent or severe issues, consult a professional tire technician.
