Ultra High Performance All-Season

Overall Rating (8.2)

The SP Sport 5000M DSST CTT is Dunlop's Ultra High Performance All-Season run-flat tire featuring Dunlop Self-Supporting Technology (DSST) and is a Combined Technology Tyre (CTT) that merges both car and motorcycle tire development and manufacturing technologies to enhance ride quality while providing temporary extended mobility. The SP Sport 5000M DSST CTT was developed for Original Equipment use on coupes, performance sedans and sporty crossover vehicles. It is designed to provide ultra high performance and all-season versatility by blending traction on dry, wet and wintry roads, including in occasional light snow.

The Dunlop Self-Supporting Technology (DSST) Combined Technology Tyre (CTT) incorporates special sidewall reinforcements that support the weight of the vehicle even after sustaining air pressure losses that would render conventional tires immobile. While internal tire damage will likely make replacement necessary, DSST CTT tires are designed to endure being run on while flat for up to 50 miles at speeds up to 55 mph and provide drivers the temporary extended mobility necessary to drive through stormy weather and away from dangerous situations.

Original Equipment self-supporting run-flat all-season tires are most often repurchased as direct replacements for pairs and sets of worn out Original Equipment tires and DSST CTT tires are only recommended for vehicles originally equipped with self-supporting run-flat tires and a tire pressure monitoring system.

The SP Sport 5000M DSST CTT molds a high performance all-season tread compound into a symmetric tread design consisting of a continuous center rib flanked by independent intermediate and shoulder blocks that blend traction, treadwear and rolling resistance to meet a wide range of driving conditions. Full-face, engineered crosscut sipes provide more biting edges for slush and snow traction. The tires' internal structure include twin steel belts reinforced by Dunlop's Jointless Band (JLB) technology that uses spirally wound nylon to provide high-speed durability while it reduces weight and helps provide more uniform ride quality.

Comments The problem with this tire is its poor durability. All it takes is a couple of Boston pot holes and the tire cups and the side walls bulge. I'm on my third set (and now need a 4th set) with 80K miles on the car. If you live in a region with well-mantained roads then I suspect you would be very happy with them as the traction and responsiveness are superb.
