2. Installation og opsætning
Proper installation is crucial for the safety and performance of your Bridgestone Alenza A/S 02 tires. It is highly recommended that tire installation be performed by a certified professional technician.
2.1 Kontrol før installation
- Køretøjskompatibilitet: Ensure the tire size (275/50R22) and specifications match your vehicle's requirements as specified in your vehicle owner's manual.

2.2 Montering og afbalancering
Tires must be mounted on approved rims using proper tools and techniques to prevent damage to the tire bead or wheel. After mounting, tires must be balanced to eliminate vibrations and ensure smooth operation. Improper balancing can lead to uneven wear and reduced tire life.
2.3 Inflation
Inflate tires to the vehicle manufacturer's recommended pressure, which can typically be found on a placard inside the driver's side door jamb, glove compartment, or in the owner's manual. Do not exceed the maximum inflation pressure molded on the tire sidewall.

4. Vedligeholdelse
Regular maintenance extends the life of your tires and ensures optimal safety and performance.
4.1 Dæktryk
Check tire pressure monthly, or before long trips, using a reliable tire gauge. Adjust pressure when tires are cold (driven less than a mile). Proper inflation is critical for safety, fuel efficiency, and even tread wear.
4.2 Dækskift
Rotate your tires every 5,000 to 7,500 miles (8,000 to 12,000 km) or as recommended by your vehicle manufacturer. Regular rotation helps promote even tread wear across all four tires.
4.3 Inspektion af slidbanedybde
Regularly inspect tread depth using a tread depth gauge or the built-in tread wear indicators. When the tread wears down to 2/32 inch (1.6 mm), the tire should be replaced. Uneven wear patterns may indicate alignment or balancing issues.
