The Dunlop SP Winter Sport 4d DSST (Dunlop Self-Supporting Technology) ROF (Run On Flat) Performance Winter /Snow tires were made specially for sedans, coupes and even sport car that were factory furnished with low profile tires set up on large alloy wheels. This features a design that enables driving even when the tire is punctured allowing complete pressure loss and is also great for use in cold winter conditions. This tire also boasts traction on wet, slushy, dry and even on snowy driving conditions.
This tire features a motor sport derived silica-plus tread compound that improves traction, especially on wet roads or in winter climate. This is shaped into a directional tread design with long v-shaped grooves that makes it resistant to hydroplaning – perfect for great grip on wet and slushy roads.
This has Dunlop’s 4D Sipe System – 3D sipe technology with extended sipes forming independent micro-blocks for better footprint pressure distribution to improve control on snow and cornering traction.
It includes twin steel belts with Dunlop’s JointLess Band (JLB) of nylon to maximize the contact patch and lessen tire growth even at high speeds. This also has sidewall reinforcements that can temporarily support the vehicle’s weight even after losing air pressure that can make other tires not usable. This enables users to drive on deflating tire up to 50 miles with speed up to 50 mph making it safer to driver away from stormy weather and danger.
NOTE: DSST tires are only recommended for vehicles originally made with self-supporting run-flat tires and tire pressure monitoring system.
This tire meets the standards for severe snow service requirements and branded with mountain/snowflake symbol.
Install these tires in sets of 4 only. Do not mix radial winter tires of other pattern, construction, ply rating or size type. Dunlop highly recommends installing 4 winter ties of the same type for maximum quality and grip to maintain their driving characteristics.
