Bridgestone 13327 Potenza Sport 265/40R21 105Y XL Summer Performance Tire

The Bridgestone Potenza Sport is an ultra-high performance summer tire engineered for sports cars, performance sedans, and SUVs demanding maximum grip in both dry and wet conditions. Featuring a special ultra-high silica compound paired with an asymmetric, ribbed tread design, the Potenza Sport delivers confident handling and shorter stopping distances whether the roads are dry or damp.

Key Features:

• Ultra-High Silica Compound: Purpose-built summer tread compound provides exceptional grip on wet and dry pavement while managing heat buildup at high speeds
• Asymmetric Tread Pattern: Non-directional asymmetric design enhances traction and cornering performance while allowing for free rotation
• 3D Sipe Technology: Improves footprint stability and maintains consistent performance as the tire wears over time
• Circumferential Grooves: Wide grooves efficiently evacuate water from the contact patch, reducing hydroplaning risk and maintaining wet traction
• Tuned Tread Sequencing: Computer-optimized tread block arrangement minimizes road noise and vibration for a refined, quiet ride
• Reinforced Shoulder Blocks: Stiffer outer shoulder promotes responsive steering feel and confident cornering at high speeds
• Extra Load (XL) Rated: Enhanced load carrying capacity suitable for heavier performance vehicles
