2007 CADILLAC CTS V wheel size

Different Size Tires and Wheels
If you add wheels or tires that are a different size
than your original equipment wheels and tires,
this may affect the way your vehicle performs,
including its braking, ride and handling
characteristics, stability, and resistance to rollover.
Additionally, if your vehicle has electronic
systems such as, anti-lock brakes, traction control,
and electronic stability control, the performance
of these systems can be affected.
{CAUTION:
If you add different sized wheels, your
vehicle may not provide an acceptable
level of performance and safety if tires not
recommended for those wheels are
selected. You may increase the chance
that you will crash and suffer serious
injury. Only use GM specic wheel and
tire systems developed for your vehicle,
and have them properly installed by a GM
certied technician.SeeBuying New Tires on page 411and
Accessories and Modications on page 332for
additional information.
Uniform Tire Quality Grading
Quality grades can be found where applicable on
the tire sidewall between tread shoulder and
maximum section width. For example:
Treadwear 200 Traction AA Temperature A
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration (NHTSA), which
grades tires by treadwear, traction, and
temperature performance. This applies only to
vehicles sold in the United States. The grades are
molded on the sidewalls of most passenger car
tires. The Uniform Tire Quality Grading (UTQG)
system does not apply to deep tread, winter-type
snow tires, space-saver, or temporary use
spare tires, tires with nominal rim diameters of
10 to 12 inches (25 to 30 cm), or to some
limited-production tires.

Tire Chains
{CAUTION:
Do not use tire chains. There is not
enough clearance. Tire chains used on a
vehicle without the proper amount of
clearance can cause damage to the
brakes, suspension, or other vehicle
parts. The area damaged by the tire
chains could cause you to lose control of
your vehicle and you or others may be
injured in a crash. Use another type of
traction device only if its manufacturer
recommends it for use on your vehicle
and tire size combination and road
conditions. Follow that manufacturer’s
instructions. To help avoid damage to
your vehicle, drive slowly, re-adjust or
remove the device if it is contacting your
vehicle, and do not spin your wheels.
If you do nd traction devices that will t,
install them on the rear tires.
Lifting Your Vehicle (CTS-V)
{CAUTION:
Lifting a vehicle can cause an injury.
The vehicle can slip off the jack and roll
over you or other people. You and they
could be badly injured. Find a level place
to lift your vehicle. To help prevent the
vehicle from moving:
1. Place the shift lever in REVERSE (R)
and rmly apply the parking brake.
2. Turn off the engine.
To be even more certain the vehicle will
not move, you can put blocks in front of
and behind the wheels. Also seeParking
Your Vehicle (Manual Transmission) on
page 132andParking Brake on page 128
for additional information.

nuts rmly in a
crisscross sequence
as shown.
Notice:Wheel covers will not t on your
compact spare. If you try to put a wheel cover
on the compact spare, you could damage
the cover or the spare.
Do not try to put a wheel cover on your compact
spare tire. It will note t. Store the wheel cover
in the trunk until you have the at tire repaired or
replaced.Storing a Flat or Spare Tire and
Tools (CTS Only)
{CAUTION:
Storing a jack, a tire, or other equipment
in the passenger compartment of the
vehicle could cause injury. In a sudden
stop or collision, loose equipment could
strike someone. Store all these in the
proper place.
After you have put the compact spare tire on your
vehicle, you will need to store the at tire in
your trunk.
Remove the foam support so that the at tire will
t in the storage area. Place the at tire with
the appearance-side face down and store the jack
container in the center of the tire. See the
diagram for more information.
The compact spare is for temporary use only.
Replace the compact spare tire with a full-size tire
as soon as you can.

K. JackCompact Spare Tire (CTS Only)
Although the compact spare tire was fully inated
when the vehicle was new, it can lose air after
a time. Check the ination pressure regularly.
It should be 60 psi (420 kPa).
After installing the compact spare on the vehicle,
stop as soon as possible and make sure the
spare tire is correctly inated. The compact spare
is made to perform well at speeds up to 65 mph
(105 km/h) for distances up to 3,000 miles
(5 000 km), so you can nish your trip and have
the full-size tire repaired or replaced at your
convenience. Of course, it is best to replace the
spare with a full-size tire as soon as possible.
The spare tire will last longer and be in good
shape in case it is needed again.
Notice:When the compact spare is installed,
do not take your vehicle through an automatic
car wash with guide rails. The compact
spare can get caught on the rails. That can
damage the tire and wheel, and maybe
other parts of your vehicle.
Do not use the compact spare on other vehicles.
