Armstrong's SKI-Trac PC is a winter tire specifically created for passenger cars. Its main goal is to provide exceptional traction and handling on various winter road conditions such as ice, slush, snow, and freezing surfaces. To enhance its performance, this tire features a uni-directional tread pattern. One of the standout features of the SKI-Trac PC is its optimized 3D sipes. These sipes are designed to grip onto the road surface, improving the tire's handling capabilities. Additionally, they play a vital role in reducing braking distances, ensuring a safer driving experience. Moreover, the tire's four circumferential grooves effectively drain water, slush, and snow from the tread, reducing the risk of hydroplaning on wet roads. The SKI-Trac PC is specifically engineered for harsh winter weather conditions. It is even certified with the Three Peak Mountain Snowflake symbol, indicating its suitability for severe winter weather. However, it's essential to note that this tire should not be used when temperatures consistently exceed 45 degrees Fahrenheit. In summary, Armstrong's SKI-Trac PC winter tire is an excellent choice for passenger cars during winter months. Its uni-directional tread pattern, optimized 3D sipes, and wide grooves ensure enhanced traction, handling, and reduced risk of hydroplaning. When using this tire, it's crucial to adhere to the recommended temperature range for optimal performance.
