2. Safety Information
Always prioritize safety when handling, installing, or operating with tires. Improper use can lead to serious injury or property damage.
- Professional Installation: It is highly recommended that tires be installed by a qualified professional using appropriate equipment.
- Tire Pressure: Maintain correct tire inflation pressure as specified by your vehicle manufacturer. Check pressure regularly, especially before long trips.
- Load Capacity: Do not exceed the maximum load capacity specified on the tire sidewall (3042 pounds for this model). Overloading can cause tire failure.
- Speed Rating: Adhere to the tire's speed rating (R for this model, indicating up to 106 mph or 170 km/h). Do not exceed safe speeds for road conditions.
- Winter Conditions: While designed for winter, exercise caution in severe conditions. Adjust driving habits to suit snow, ice, and slush.
- Tire Inspection: Regularly inspect tires for cuts, bulges, punctures, or uneven wear. Replace damaged tires immediately.
3. Setup and Installation
Proper installation is crucial for tire performance and safety. It is strongly advised to have these tires mounted by a certified tire technician.
- Rim Compatibility: Ensure the tire (LT245/75R16) is mounted on a compatible rim with a width of 7 inches.
- Mounting: Use proper tire mounting equipment to avoid damage to the tire bead or rim. Lubricate the bead area adequately.
- Inflation: Inflate the tire to the vehicle manufacturer's recommended pressure, typically found on a placard inside the driver's door jamb or in the owner's manual. The maximum pressure for this tire is 80 PSI.
- Balancing: After mounting, balance the tire and wheel assembly to prevent vibrations and ensure even wear.
- Lug Nut Torque: Torque lug nuts to the vehicle manufacturer's specifications. Re-check torque after the first 50-100 miles of driving.

4. Operating Guidelines
The Bridgestone Blizzak LT is engineered for superior performance in winter conditions. Follow these guidelines for optimal operation:
- Winter Use Only: These tires are specifically designed for winter conditions. For best performance and longevity, they should be removed and stored during warmer months.
- Driving in Snow and Ice: Drive cautiously, reduce speed, and increase following distance. Avoid sudden acceleration, braking, or steering inputs.
- Tire Pressure Monitoring: Regularly check tire pressure, especially as temperatures fluctuate. Cold weather causes tire pressure to drop.
- Load Distribution: Ensure vehicle load is distributed evenly and does not exceed the tire's load capacity.

5. Maintenance
Regular maintenance extends the life of your tires and ensures continued safety and performance.
- Tire Rotation: Rotate tires every 5,000 to 7,500 miles, or as recommended by your vehicle manufacturer, to promote even wear.
- Tread Depth: Monitor tread depth regularly. The Blizzak LT has a tread depth of 17/32nds when new. Replace tires when tread depth reaches 4/32nds of an inch for winter tires, or sooner if required by local laws.
- Alignment: Ensure your vehicle's wheel alignment is checked periodically, especially if you notice uneven tire wear or steering issues.
- Cleaning and Storage: Clean tires with mild soap and water. When storing for the off-season, clean them thoroughly, ensure they are dry, and store them in a cool, dry place away from direct sunlight and chemicals.

6. Troubleshooting
This section addresses common issues you might encounter with your tires.
| Issue | Possible Cause | Solution |
|---|---|---|
| Uneven Tread Wear | Improper inflation, misalignment, unbalanced wheels, lack of rotation. | Check and adjust tire pressure. Have alignment and balancing checked by a professional. Implement regular tire rotation. |
| Vibrations While Driving | Unbalanced wheels, bent rim, tire damage, suspension issues. | Have wheels re-balanced. Inspect tires and rims for damage. Consult a mechanic for suspension check. |
| Frequent Loss of Air Pressure | Puncture, leaky valve stem, damaged rim, bead leak. | Inspect tire for punctures. Check valve stem. Have tire and rim inspected by a professional for leaks. |
| Reduced Winter Performance | Worn tread, improper inflation, incorrect tire type for conditions. | Check tread depth and replace if worn. Verify tire pressure. Ensure these are indeed winter tires and not all-season. |
