TIRE INFORMATION
Your SVT vehicle is equipped with unique wheels and tires designed to
enhance performance. To continue providing this performance, extra
care must be taken when operating and maintaining your vehicle.

Tires
Your SVT vehicle is equipped with low profile, high performance tires
that are designed to optimize the driving dynamics you expect in a SVT
vehicle. These tires are not optimized for off-road or winter (snow or
cold weather) performance, and their ride, noise and wear characteristics
are different than non-performance tires. Also, because of their lower
profile, the tires are more susceptible to damage due to potholes and
rough roads. To ensure that your tires perform as intended, it is
important that you maintain your tires properly:
•The Shelby GT500 original equipment tires are optimized for
performance in both wet and dry conditions. Ford does not
recommend using the original equipment tires when temperatures
drop to approximately 40°F (5°C) or below (depending on tire wear
and environmental conditions) or in snow/ice conditions.

•The Shelby GT500 optional P265/40-19 front, P285/35-20 rear
directional tires were designed for track use and may exhibit
significantly reduced tread life and increased tire noise compared to
the standard equipment tires under normal driving conditions.
Increasing the front camber settings beyond the factory settings may
further accelerate tread wear and induce tire noise.
•Do not use tire chainson the original wheels and tires of your
vehicle. The use of any type of tire chain on these tires may damage
your vehicle.
•For tire pressures, see the placard located on the B-pillar inside the
driver’s door.
•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.
•Inspect your tires for damage on a regular basis. If a tire is damaged,
replace it immediately.
•Proper suspension alignment is critical for maximum performance and
optimal tire wear. If you notice uneven tire wear, have your alignment
checked.
•Rotate tires as recommended in the following sectionTire rotation.
•When replacing tires, the only way to ensure original performance is
to use the original equipment tire. If a different tire is used, it should
be the same size, speed rating and load rating and be replaced as a set
of four. Never mix tire brands.

WARNING:For vehicles equipped with optional performance
package tires (P265/40-19 front, P285/35-20 rear), only replace
wheels and tires with the EXACT original brand, size and construction
tire with which your vehicle was originally equipped. Use of any other
wheel/tire combinations, even with identical size ratings, may result in
insufficient running clearances, tire rubbing and eventual puncture.
Loss of tire pressure could lead to a loss of vehicle control leading to
serious injury or death.
Summer tires
The Shelby GT500 Performance Package is equipped with 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 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 guide. Ford does not
recommend using these high performance summer tires when
temperatures drop to approximately 40°F (5°C) or below, or in snow/ice
conditions.
Winter driving
The original equipment tires on your SVT vehicle are designed for
maximum performance in dry and wet summer conditions. They are not
designed for winter use on ice or snow and cannot be used with snow
chains. If you will be operating your vehicle in these conditions, winter
or all-season tires must be used.
•Use winter tires with a “V” speed rating and a 93 load index or higher
for all models. You may also use P255/45R-18 winter tires with a “V”
speed rating and a 93 load index and 18 in. wheels from the
2007-2010 model year Shelby GT500. Using these wheels will ensure
adequate brake and suspension clearance.
