Bridgestone 6449 DriveGuard Plus RFT 225/65R17 102H All-Season Run-Flat Touring Tire

The Bridgestone DriveGuard Plus (MPN: 6449) is an all-season grand touring run-flat tire engineered to deliver confident everyday performance without sacrificing safety or comfort. Sized at 225/65R17 with a 102H service description and a black sidewall, this tire combines extended mobility technology with a refined tread design built for year-round driving.

Run-Flat Technology:

• Reinforced internal sidewall structure supports the full weight of the vehicle even at zero tire pressure
• Engineered for up to 50 miles of continued driving at up to 50 mph after a puncture or complete loss of air pressure
• Integrated heat-dissipating design reduces heat buildup during low-pressure operation

All-Season Performance:

• Asymmetric tread pattern with zero-degree draft angles enhances grip in dry, wet, and winter conditions
• Improved snow and ice stopping performance — stops up to 40 feet shorter in snow compared to the original DriveGuard
• Full-depth main grooves and open shoulder slots force water out of the tread to reduce hydroplaning risk
• Full-depth 3D sipe technology enhances wet and winter traction while promoting even tread wear
• M+S rated for mud and light snow traction

Comfort & Longevity:

• Inboard tread design minimizes road noise and cabin vibrations for a quieter, more comfortable ride
• NanoPro-Tech rubber compound distributes weight evenly for long, consistent tread life
