Approved Winter Tire Summary
Information:
Summer and winter tires have opposite, seasonal, and specific applications. This is particularly true for high performance Porsche vehicles equipped with
wide "ZR" tires designed for safety on dry and wet roads.
The cold weather performance of summer tires is not adequate for winter conditions and their use is discouraged under those conditions.
Summer tires at temperatures below 50 Celsius (41° F) exhibit a decrease in their ability to adhere to the road surface. Installation of the approved winter
tire/wheel combinations during cold weather conditions is strongly recommended.
