Dunlop SP Sport 01 DSST Run-Flat Summer Performance Tire

The Dunlop SP Sport 01 DSST (Dunlop Self-Supporting Technology) is an ultra-high performance summer run-flat tire engineered for sports cars, coupes, performance sedans, and luxury passenger vehicles. Originally developed as original equipment for leading automotive manufacturers, the SP Sport 01 DSST combines the responsive handling and confident dry/wet grip of a true summer performance tire with the extended mobility and peace of mind that Dunlop's patented run-flat technology delivers.

Dunlop Self-Supporting Technology (DSST) — Run-Flat Performance:

• Patented Run-Flat Sidewall Construction: Specially reinforced sidewalls and purpose-developed rubber compounds support the vehicle's weight even after a complete loss of air pressure, enabling continued mobility for up to 50 miles at speeds up to 55 mph
• TPMS Compatible: Designed for vehicles equipped with a tire pressure monitoring system, ensuring the driver is always alerted to pressure changes before and during a flat-tire event
• OE-Grade Engineering: Developed alongside leading automotive manufacturers as original equipment, making this tire the trusted direct-replacement choice for worn OE run-flat fitments

Performance & Handling Technology:

• 100% Silica Tread Compound: Enhances dry and wet traction while simultaneously reducing rolling resistance for improved fuel efficiency and extended treadwear
• Asymmetric Tri-Area Tread Design: Three distinct tread segments blend sportiness and safety, maintaining consistent road contact for sharp steering response and confident cornering stability
• Circumferential & Wave Grooves: Efficiently disperse water from the contact patch to resist hydroplaning and maintain grip in wet conditions
• Jointless Band Technology (JLB): Spirally wrapped nylon reinforcement maintains the tire's ideal shape under high-speed driving pressure, delivering smooth, stable performance at highway speeds
• Twin Steel Belt Construction: Rayon cord-reinforced casing with twin steel belts provides high-speed durability and structural integrity throughout the tire's service life
• Aramid-Reinforced Bead: High-strength aramid fibers deliver a tight, precise rim fit while enhancing steering responsiveness
• Max Flange Shield: Protective rim flange design guards wheels against accidental curb damage during everyday driving
