The Continental WinterContact SI tire is a new winter tire that features PolarPlus+ Technology for ultimate grip in snow, ice & wet conditions.
PolarPlus is a new rubber compound that has a very high silica content mixed in with the natural and synthetic rubber. The tire also features variable depth sipes on both shoulders of the tire which can alert the driver or mechanic inspecting the tires during maintenance intervals to any irregular wear on the tire. A very helpful feature which allows for early detection of vehicle mechanical problems, alignment or tire air pressure issues.
The Continental WinterContact SI tires meet the industry's severe snow service requirements and most sizes are branded with the mountain/snowflake symbol.
