Continental ExtremeContact DW Tuned 245/35R21, Summer, High Performance tires.

Features and Benefits: Summer weather traction; Tuned Performance Indicators; Precise steering responsiveness; Reduced road vibrations; Continental ExtremeContact DW Tuned TiresThe Continental ExtremeContact DW Tuned is a high performance, summer tire made for passenger vehicles and SUVs. The tire offers excellent controllability. The tread design's continuous outer rib and shoulder tread block pattern upgrade the road contact, boosting the steering responsiveness and the driving stability. As a result, the tire ensures a quick and precise steering response to the driver's commands, while the structure is secured against the driving pressure. The shoulder block pattern enhances the cornering ability with the use of extra biting edges. This combination ensures the driver's better control over the vehicle. The model ensures a summer weather performance. The special silica compound and the tread design upgrade the dry and wet weather traction. The better road contact allows the tire to optimize the surface contact, while the compound avoids heat resistance. This model is not suited for winter weather conditions. The ideal circumferential grooves prevent hydroplaning by dispersing water from the footprint, enhancing the wet weather traction and driving ability. The tread design's Tuned Performance Indicators place the letters D and W on the center tread rib of the outer tire shoulder. The letters represent the dry and wet weather traction and these letters wear away with the tread. When the W letter disappears, the tire loses its wet weather traction. This allows the driver to follow the tire's treadwear rate, ensuring that the tire is not driven on when its tread is worn-out. The Continental ExtremeContact DW Tuned promotes a comfortable performance and excellent high speed durability. The tire features a twin steel belt structure which maintains the ideal tire shape under the driving pressure. As the tire does not deform, it is able to securely perform at its best high speed ability. The close surface contact enables the tire to absorb the shock of driving, reducing the road vibrations felt by the passengers. Manufacturers recommend changing tires every 10 years. As long as tires are properly stored before they are sold, the year of their manufacture will not shorten their service life.
