Its standout feature is Dunlop's patented Self-Supporting Technology, which allows you to keep driving up to 50 miles at 55 mph after a complete loss of air pressure. The result is confident, composed performance without sacrificing ride refinement or cabin quietness.\u003c\/p\u003e\n\u003cp\u003eAn asymmetrical tread pattern works alongside a silica-enriched compound to sharpen grip on both dry and wet pavement while keeping rolling resistance in check.

Based in Akron, OH, the company now operates as part of Sumitomo Rubber Industries. Dunlop has also established itself as an original equipment supplier to a number of well-known automotive manufacturers.\u003c\/p\u003e\u003cp\u003eOn the motorsport side, Dunlop's competitive history includes a Le Mans victory in 1926 and a strong presence in Formula 1 racing. The brand's tire lineup spans passenger cars, light trucks, CUVs, SUVs, and commercial vehicles, covering categories such as winter, all-season, touring, ultra-high-performance summer, and track competition. Notable product families include the Grandtrek, Signature, SP Sport, and Winter Maxx.\u003c\/p\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eWhat does 245\/40R1893Y mean?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e245 is the tread width in millimeters, 40 means the sidewall is 40% of that width, and R18 is the 18-inch rim it mounts on. 93 is the load index (1,433 lbs per tire), and Y is the speed rating (up to 186 mph).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow does the run-flat technology on this tire work?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eDunlop's Self-Supporting Technology (DSST) uses a reinforced sidewall construction combined with a specially formulated rubber compound to bear the vehicle's weight even when the tire has lost air pressure. This allows continued driving up to 50 miles at speeds no greater than 55 mph under normal conditions. It's designed to get you to a service location safely rather than leaving you stranded.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I use the SP Sport 01 DSST in winter or snowy conditions?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis tire is not Three-Peak Mountain Snowflake certified and is not designed for severe winter service. It is best suited to warm and mild weather driving. Drivers in climates with regular snow or ice should consider a dedicated winter tire for those months.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this tire require a specific wheel or TPMS system?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eRun-flat tires like the SP Sport 01 DSST must be paired with a Tire Pressure Monitoring System (TPMS), since you may not feel a pressure loss the way you would with a conventional tire. No special wheel design is required beyond standard compatibility with your vehicle's rim size, but verifying TPMS functionality is essential for safe run-flat operation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the mileage warranty on the SP Sport 01 DSST?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis model carries a manufacturer warranty.
