Bridgestone 012358 Turanza LS100 A Run Flat 225/45R18 91H All-Season Touring Tire

The Bridgestone Turanza LS100 A Run Flat (MPN: 012358) is a grand touring all-season passenger tire engineered to meet demanding original equipment manufacturer (OEM) specifications. Designed as original equipment on select vehicles — including select Mercedes-Benz RunFlat models — this 225/45R18 91H tire delivers the quiet, comfortable, and confident ride performance that matches the vehicle's originally intended driving characteristics.

Equipped with Run Flat technology, the Turanza LS100 A features reinforced sidewall construction that maintains its shape after a complete loss of air pressure, allowing continued driving for up to 50 miles at speeds up to 50 mph — keeping drivers safely mobile without the need for an immediate roadside tire change.

Key Features:

• Run Flat Technology: Reinforced sidewalls support vehicle weight after pressure loss, enabling up to 50 miles of continued driving at up to 50 mph
• OE-Tuned Tread Pattern: Optimized for outstanding original equipment performance in both wet and dry conditions
• Wide Circumferential Grooves: Channel water away from the contact patch to reduce hydroplaning and maintain grip in wet conditions
• Innovative All-Season Compound: Silica-enhanced compound maintains rubber flexibility across a range of temperatures for dry, wet, and light winter traction
• Embedded Sipes and Ribbed Design: Enhance steering responsiveness, driving stability, and braking performance by increasing biting edges and surface contact
• Noise-Reduction Tread Sequencing: Tuned tread block pattern minimizes road noise for a quieter, more refined cabin experience
• M+S Rated: Meets Mud and Snow performance standards for all-season confidence
• UTQG: 560 A A — Treadwear 560, Traction A, Temperature A
