The Mustang Boss 302 Laguna Seca package includes D.O.T. approved
ultra high-performance summer tires with track capability. The rubber
compounds used in these tires lose flexibility and may develop surface
cracks in the tire tread area at temperatures below 20°F (-7°C). Always
store your tires indoors at temperatures above 20°F (-7°C). If the tires
have been subjected to 20°F (-7°C) or less, warm them in a heated space
to at least 40°F (5°C) for at least 24 hours before installing them on a
vehicle, or moving the vehicle with the tires installed, or checking tire
inflation. 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 the tires after storage
periods and before use as outlined in the owner’s manual. Ford does not
recommend using the high performance summer tires on your Boss 302
or Boss 302 Laguna Seca edition when temperatures drop to
approximately 40
oF(5oC) or below, or in snow/ice conditions.
WARNING:If equipped with the Laguna SecaPackage, never
drive with these tires in any wet conditions (rain, snow, ice, etc.)
because they cannot channel water away and will slide risking serious
injury.
•Note:Do not use tire chains on the original wheels and tires of your
vehicle. The use of any type of tire chain on these tires may damage
your vehicle.
•Always maintain your tire pressures according to the tire information
placard on the driver’s door jamb, using an accurate gauge.
•Tire pressures are specified “cold” and should be checked after the
vehicle has been parked for at least 3 hours. Do not reduce pressure
of warm tires.
•Check your tire pressure often to maintain it properly. Tire pressure
can diminish over time and fluctuate with temperature.
•Do not overload your vehicle. Maximum vehicle and axle weights are
listed on the tire information placard.
•Extra caution should be taken when operating the vehicle near its
maximum load, including assuring proper tire pressure and reducing
speeds.
•Extra caution should be taken when operating on rough roads to avoid
impacts that could cause tire damage.
•In the event that you encounter an abnormally harsh impact, inspect
your tires for damage.
