INFORMATION
Subject:

Information on Goodyear F1 Supercar G2 Tire Cold Weather Cracking

Models:

2012-2013 Chevrolet Camaro ZL1
2013 Chevrolet Camaro SS with RPO 1LE

Cold Weather Operation
The Camaro ZL1 and RPO 1LE vehicles come with
285/35ZR20 and/or 305/35ZR20 Goodyear F1
Supercar G2 D.O.T. approved ultra high performance,
track capable summer tires as standard equipment.
Goodyear F1 Supercar Performance tires are a
summer season tire and are not intended to be driven
on snow, ice or road surfaces below -7°C (20°F).
If the ambient temperature in your location is at or
below -7°C (20°F), DO NOT MOVE THIS VEHICLE.
The rubber used in these tires loses flexibility and may
develop surface cracks in the tire tread/shoulder area
at colder temperatures. Driving the vehicle, when the
temperature is below -7°C (20°F), may result in surface
cracks in the tread area of the tire. Surface cracks are
cosmetic and will not result in a loss of air.

Tire Surface Cracks

Special tread and compounds used on these
performance tires will cause a decrease in performance
in cold climates. Driving with ultra high performance
summer tires on snow, ice or cold road surfaces may
cause loss of control. Refer to the latest version of
Corporate Bulletin Number 04-03-10-013: Driving
Characteristics of Rear Wheel Drive Vehicles and
Available Winter Tires for further information on
available replacement winter tires for cold climate
operation.

Tire Storage
It is recommended that Goodyear F1 Supercar G2 tires
are stored indoors at temperatures above -7°C (20°F)
when not in use. If the tires have been subjected to
-7°C (20°F) or less, let them warm up in a heated space
to at least 5°C (40°F) for 24 hours or more before being
installed or driving a vehicle on which they are installed.
Inflate the tires only after they have been warmed
above 5°C (40°F). 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 being
stored.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
