Bridgestone 8415 DriveGuard Plus 255/55R18 109W XL Run Flat All-Season Tire

The Bridgestone DriveGuard Plus is a grand touring all-season tire designed for drivers of sedans, coupes, crossovers, and SUVs who demand enhanced luxury with advanced run-flat capabilities and reliable year-round traction. This tire features Bridgestone's next-generation run-flat technology, making it ideal for replacement on TPMS-equipped vehicles whether or not they originally came with run-flat tires from the factory.

Run-Flat Technology:

The DriveGuard Plus delivers peace of mind with its self-supporting run-flat design. Reinforced sidewalls allow you to continue driving for up to 50 miles at speeds up to 50 mph after experiencing a puncture or complete air pressure loss, giving you the flexibility to reach a safe location for tire repair or replacement.

Key Features:

• Full-Depth 3D Sipe Technology: Provides strong traction on wet and snowy roads while reducing uneven wear for extended tread life
• Asymmetric Tread Pattern: Enhances handling performance in dry, wet, and light winter conditions with stiffer outboard shoulder blocks for stable cornering and braking
• Open Shoulder Slots and Full-Depth Grooves: Efficiently evacuate water to reduce hydroplaning risk and improve wet weather performance
• Zero-Degree Draft Angles: Delivers superior gripping power in all weather conditions, stopping up to 40 feet shorter in snow compared to the original DriveGuard
• Inboard Design: Reduces road noise and vibrations for a quiet, comfortable ride
• Cooling Fin Technology: Dissipates heat generated during zero-pressure operation, minimizing rigid construction and maximizing comfort

Performance and Warranty:

This tire carries a UTQG rating of 640AA and comes with Bridgestone's 65,000-mile limited treadwear warranty. The 109W service description indicates a maximum load capacity of 2,271 lbs per tire and a speed rating of 168 mph. Designed for all-season versatility, the DriveGuard Plus excels in dry and wet conditions while providing confident traction in light snow, though it is not Three Peak Mountain Snowflake certified for severe winter use.
