Subject: Eagle F1 Supercar G:2 Summer Tires Not Recommended for Winter Use
Goodyear F1 Supercar G:2’s are D.O.T. approved ultra high performance summer tires with track capability. The rubber used in these tires loses flexibility and may develop surface cracks in the tire tread/shoulder area at colder temperatures. Goodyear does not recommend using these high performance summer tires when temperatures drop to approximately 40 deg F (5 deg C) or below, or in snow/ice conditions.
Tire Storage
Follow the general tire storage recommendations in Product Service Bulletin 2010-21, Proper Procedures for the Storage of Tires. Further, it is recommended for these tires to be stored indoors at temperatures above 20 deg F (-7 deg C) when not in use. If the tires have been subject to 20 deg F (-7 deg C) or less, let them warm up in a heated space to at least 40 deg F for 24 hours or more before installation or driving the vehicle. Inflate the tires only after they have been warmed above 40 deg F (5 deg C). Do not place tires near heaters or heating devices used to warm the room where the tires are stored. Do not apply heat or blow heated air directly on the tires. Always inspect tires before use after storage periods as outlined in the Proper Procedures for the Storage of Tires bulletin.
