Dunlop SP Sport 5000 DSST CTT Run-Flat All-Season Performance Tire

The Dunlop SP Sport 5000 DSST CTT is an ultra-high-performance all-season run-flat tire engineered for drivers who demand year-round capability without compromising ride quality or safety. This tire line pairs Dunlop's proven Self-Supporting Technology (DSST) with Combined Tire Technology (CTT) — a combination that delivers continued mobility after a complete loss of air pressure while providing a noticeably more refined ride than conventional run-flat designs. Frequently specified as original equipment on sports cars, performance coupes, high-performance sedans, and sporty crossovers, the SP Sport 5000 DSST CTT is a trusted direct-replacement choice for TPMS-equipped vehicles.

Run-Flat Technology & Safety:

• Dunlop Self-Supporting Technology (DSST): Patented reinforced sidewall construction allows continued driving up to 50 miles at 50 mph after a complete loss of air pressure, eliminating the need for an immediate roadside tire change
• Combined Tire Technology (CTT): Reduces overall tire weight and optimizes the internal cavity shape for improved steering responsiveness, driving stability, and a softer, more comfortable ride compared to conventional run-flat tires
• Max Flange Shield®: A protective rim shield guards wheels against curb damage and abrasion during everyday parking and maneuvering (available on select sizes)
• Noise Shield Technology: Select sizes feature a manufacturer-applied layer of sound-absorbing foam bonded to the inner liner to further reduce cabin noise

All-Season Performance:

• Asymmetrical Tread Design: Balances dry-road grip with wet-weather traction for confident, responsive handling across a wide range of driving conditions
• Large Independent Shoulder Tread Blocks: Deliver dry cornering stability and precise steering response for spirited, controlled driving
• Circumferential & Lateral Grooves: Efficiently channel water and slush away from the contact patch to actively resist hydroplaning and maintain wet-road traction
• Jointless Band Technology™: A spirally wrapped cord over twin-cut steel belts maintains consistent tire shape and uniformity at highway speeds, providing a stable, flat footprint and smooth high-speed performance
• High-Performance All-Season Compound: Specialized rubber formulation promotes even tread wear and reliable grip across a broad temperature range, including light snow

The SP Sport 5000 DSST CTT product line is backed by Dunlop's Highway Auto and Light Truck Tire Replacement Limited Warranty, covering most qualifying passenger tire applications. As with all run-flat tires, this product line is recommended exclusively for vehicles originally equipped with self-supporting run-flat tires and a Tire Pressure Monitoring System (TPMS). Available in a wide range of fitments to suit various performance vehicles.
