Bridgestone 011799 DriveGuard 225/45R18 95W Run-Flat All-Season Touring Tire

The Bridgestone DriveGuard 225/45R18 95W (MPN: 011799) is a grand touring all-season run-flat tire built for drivers who demand both everyday comfort and the security of extended mobility after a flat. Engineered with Bridgestone's proprietary Run-Flat Technology, the DriveGuard allows continued driving for up to 50 miles at a maximum speed of 50 mph even after a complete loss of tire pressure — eliminating the need to change a tire roadside in dangerous or inconvenient conditions.

Key Features:

• Run-Flat Technology with NanoPro-Tech Sidewall Reinforcement — Reinforced sidewalls use Bridgestone's NanoPro-Tech rubber compound to support the full weight of the vehicle at zero pressure, providing temporary extended mobility after a puncture.
• Cooling Fin Design — Proprietary cooling fins integrated into the sidewall create airflow around the tire to dissipate heat and reduce friction during low-pressure operation, a critical feature for run-flat durability.
• Silica-Enhanced All-Season Tread Compound — A silica and special rubber polymer blend improves wet-weather grip and cornering stability while contributing to long tread life.
• Asymmetric Tread Pattern — An optimized asymmetric design blends predictable handling and cornering stability with all-season capability, including light snow traction.
• Wide Circumferential Grooves & Engineered Sipes — Circumferential and cross grooves evacuate water to resist hydroplaning, while sipes increase biting edges for enhanced wet and winter traction.
• Twin Steel Belt Construction — Spirally wrapped nylon over twin steel belts reinforces the tire structure for improved durability and puncture resistance.
• Optimized Contact Patch — Even weight distribution across the full contact patch promotes uniform wear for extended tread life.
• Extra Load (XL) Rated — Supports up to 1,521 lbs load capacity with a maximum inflation pressure of 50 PSI.
• UTQG 460 A A — Rated 460 for treadwear, A for traction, and A for temperature resistance.
• 50,000-Mile Limited Treadwear Warranty — W-speed-rated sizes backed by a 50,000-mile manufacturer treadwear warranty.

The DriveGuard is equally suited as a replacement for vehicles originally equipped with run-flat tires, or as an upgrade for safety-minded drivers whose vehicles did not originally include run-flat capability. Its all-season compound provides year-round performance on dry, wet, and light snow-covered roads.
