Continental WinterContact SI Plus is a friction Nordic-type winter tire for passenger cars, SUVs, and minivans, only available to consumers through the Canadian distributing company Canadian Tire. This tire is characterized by high hydroplaning resistance, and powerful grip on snow and ice. The Continental WinterContact SI Plus tire model, which has been launched on the market in 2020, differs from its predecessor, WinterContact SI (Snow and Ice) with improved wet pavement and snow performance. This was achieved, by optimizing the V-shaped tread pattern, which led to increasing the edge effect, as well as by the use of the patented technology Continental PolarPlus+, which consists in including silane additives. The special “traction” grooves are designed in such a way as to give the driver confidence on the road in the most challenging winter conditions. The system of tire wear indicators in the central section of the tread helps to extend the tire’s running life by making it possible to visually detect uneven tread wear due to the vehicle’s misalignment.
