The ExtremeContact DWS (tuned for Dry, Wet & Snow) is uniquely engineered to revolutionize the tire market with its outstanding all-season capabilities. This tire is slated to outperform when it comes to dry and wet conditions in both handling and braking; tread life, snow traction, noise, ride comfort and fuel efficiency.
Now the new ExtremeContact DWS is engineered to deliver improved performance, a modern tread pattern, and a new sidewall design with recessed serrated latters and a smooth wheel protection flange rib.
Dry performance technology “Chamfered Edges” is included in the Continental ExtremeContact DWS. This Continental ExtremeContact DWS technology for dry road surfaces generate greater acceleration grip, handling and braking traction in dry conditions. Aided by a solid outer shoulder and chamfered pattern edges, Continental Tire’s engineers concentrate on maximum surface contact. Chamfered pattern edge is unique to the Continental ExtremeContact family of ultra high performance tires.
To chamfer the pattern edge means to cut the normal 90 degree block edge(as seen highlighted below) into two 45 degree angles. This chamfered edge has a dramatic affect when the tires tread pattern is tested to the limit. When the pattern is under load from acceleration, lateral handling or braking, the standard tread block buckles creating reduced road surface contact and results in traction reduction. The chamfered tread block, in comparison, under load becomes flatter with increased road surface contact. The result, increased traction. This feature gives the driver of the Continental ExtremeContact DW added confidence in the most demanding performance conditions.
The Continental ExtremeContact DWS has excellent grip in wet conditions provided by a high void to tread pattern with optimal groove angles. Void to tread ratio means the amount of void area in the tread (as seen highlighted below) vs. the amount of tread pattern making contact with the road surface.
This void allows water to be absorbed into the pattern and then quickly evacuated. This evacuation process happens thousands of times a minute while driving in standing water giving the driver additional confidence in wet conditions.
The Continental ExtremeContact DWS has excellent grip on snow covered roads provided by the extreme number of biting edges and a new feature “Traction Grooves”. To understand this technology, we should look at the nature of snow. Snowflakes are all unique individual shapes. These individual flakes, when compressed, interlock as like a jigsaw puzzle providing a solid, stable object. The most common example is the interlocking nature of making a snow ball. When the snow is compressed (as seen here) the snow adheres to itself. When driving on the road surface, we want to capitalize on this pressure stabilizing effect. Continental Tires engineers designed the extreme number of biting edges (as seen highlighted below) and then maximized the performance of the grooves by putting biting teeth inside the grooves (as seen highlighted below).These biting teeth keep the packed snow from sliding thought the grooves. Therefore, adding grip to an area of the tire that was in the past a negative to snow grip. This new feature is unique to the Continental ExtremeContact DWS.
The Continental ExtremeContact DWS has industry leading treadlife combined with lower rolling resistance improving energy delivery to the road surface. This outstanding combination of traction, long wear and reduced rolling resistance is accomplished thought “Dynamic Temperature Distribution”. This technology is found in the curing process. Continental Tires engineers and chemists have developed the optimal curing combination of time an temperatures. This Dynamic Temperature Distribution unique heat concentration and optimized curing time increases the chemical distribution, enhancing the intermolecular structure for reduced tread distortion. This reduced distortion improves energy delivery, treadlife and lowers rolling resistance. When looking at these finite element models, the reduction of heat build-up is reduced with this technology. This gives the consumer the confidence we are keeping the environment in the forefront of our technologies. Reduced pattern distortion generates less heat and uses less energy
And like the ExtremeContact DW, this tire also features the Tuned Performance Indicators built into the tread. In this case, the “D” indicates the tire is at optimum tread depth for dry conditions. “W” indicates the tire is at optimum tread depth for wet conditions, and the “S” indicates the tire is at optimum tread depth for snow conditions. When the indicators disappear, the tire is no longer tuned for optimum performance in that particular road condition.
