2018 Alfa Romeo 4C Spider wheel

Keep dismounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact
with oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of
many characteristics. They should be inspected regu-
larly for wear and correct cold tire inflation pressures.
The manufacturer strongly recommends that you use
tires equivalent to the originals in size, quality and
performance when replacement is needed. Refer to the
paragraph on “Tread Wear Indicators” in this section.
Refer to the Tire and Loading Information placard or
the Vehicle Certification Label for the size designation
of your tire. The Load Index and Speed Symbol for your
tire will be found on the original equipment tire side-
wall.
See the Tire Sizing Chart example found in the “Tire
Safety Information” section of this manual for more
information relating to the Load Index and Speed
Symbol of a tire.
It is recommended to replace the two front tires or two
rear tires as a pair. Replacing just one tire can seriouslyaffect your vehicle’s handling. If you ever replace a
wheel, make sure that the wheel’s specifications match
those of the original wheels.
It is recommended you contact your authorized tire
dealer or original equipment dealer with any questions
you may have on tire specifications or capability. Fail-
ure to use equivalent replacement tires may adversely
affect the safety, handling, and ride of your vehicle.
WARNING!
•
Do not use a tire, wheel size, load rating, or speed
rating other than that specified for your vehicle.
Some combinations of unapproved tires and
wheels may change suspension dimensions and
performance characteristics, resulting in changes
to steering, handling, and braking of your vehicle.
This can cause unpredictable handling and stress
to steering and suspension components. You
could lose control and have a collision resulting
in serious injury or death. Use only the tire and
wheel sizes with load ratings approved for your
vehicle.

WARNING!
Do not use Summer tires in snow/ice conditions.
You could lose vehicle control, resulting in severe
injury or death. Driving too fast for conditions also
creates the possibility of loss of vehicle control.
Snow Tires
Some areas of the country require the use of snow tires
during the Winter. Snow tires can be identified by a
“mountain/snowflake” symbol on the tire sidewall.If you need snow tires, select tires
equivalent in size and type to the
original equipment tires. Use snow
tires only in sets of four; failure to do
so may adversely affect the safety
and handling of your vehicle.
Snow tires generally have lower speed ratings than
what was originally equipped with your vehicle and
should not be operated at sustained speeds over 75 mph
(120 km/h). For speeds above 75 mph (120 km/h) refer
to original equipment or an authorized tire dealer for
recommended safe operating speeds, loading and cold
tire inflation pressures. While studded tires improve performance on ice, skid
and traction capability on wet or dry surfaces may be
poorer than that of non-studded tires. Some states
prohibit studded tires; therefore, local laws should be
checked before using these tire types.
Spare Tires — If Equipped
NOTE:
For vehicles equipped with Tire Service Kit
instead of a spare tire, please refer to “Tire Service Kit”
in “In Case Of Emergency” for further information.
CAUTION!
Because of the reduced ground clearance, do not
take your vehicle through an automatic car wash
with a compact or limited use temporary spare
installed. Damage to the vehicle may result.

only. You can identify if your vehicle is equipped with
a compact spare by looking at the spare tire description
on the Tire and Loading Information Placard located on
the driver ’s side door opening or on the sidewall of the
tire. Compact spare tire descriptions begin with the
letter “T” or “S” preceding the size designation. Ex-
ample: T145/80D18 103M.
T, S = Temporary Spare Tire
Since this tire has limited tread life, the original equip-
ment tire should be repaired (or replaced) and rein-
stalled on your vehicle at the first opportunity.
Do not install a wheel cover or attempt to mount a
conventional tire on the compact spare wheel, since the
wheel is designed specifically for the compact spare
tire. Do not install more than one compact spare tire and
wheel on the vehicle at any given time.
WARNING!
Compact and collapsible spares are for temporary
emergency use only. With these spares, do not drive
more than 50 mph (80 km/h). Temporary use spares
have limited tread life. When the tread is worn to

wheel. Keep inflated to the cold tire inflation pres-
sures listed on your Tire and Loading Information
Placard located on the driver ’s side B-Pillar or the
rear edge of the driver ’s side door. Replace (or
repair) the original equipment tire at the first op-
portunity and reinstall it on your vehicle. Failure to
do so could result in loss of vehicle control.
Wheel And Wheel Trim Care
All wheels and wheel trim, especially aluminum and
chrome plated wheels, should be cleaned regularly
using mild (neutral Ph) soap and water to maintain
their luster and to prevent corrosion. Wash wheels with
the same soap solution recommended for the body of
the vehicle and remember to always wash when the
surfaces are not hot to the touch.
Your wheels are susceptible to deterioration caused by
salt, sodium chloride, magnesium chloride, calcium
chloride, etc., and other road chemicals used to melt ice
or control dust on dirt roads. Use a soft cloth or sponge and mild soap to wipe away promptly. Do not use harsh
chemicals or a stiff brush. They can damage the wheel’s
protective coating that helps keep them from corroding
and tarnishing.
CAUTION!
Avoid products or automatic car washes that use
acidic solutions or strong alkaline additives or
harsh brushes. Many aftermarket wheel cleaners
and automatic car washes may damage the wheel’s
protective finish. Such damage is not covered by the
New Vehicle Limited Warranty. Only car wash soap,
Mopar Wheel Cleaner or equivalent is recom-
mended.
When cleaning extremely dirty wheels including exces-
sive brake dust, care must be taken in the selection of
tire and wheel cleaning chemicals and equipment to
prevent damage to the wheels. Mopar Wheel Treatment
or Mopar Chrome Cleaner or their equivalent is recom-
mended or select a non-abrasive, non-acidic cleaner for
aluminum or chrome wheels.

SERVICING AND MAINTENANCE 249

CAUTION!
Do not use scouring pads, steel wool, a bristle
brush, metal polishes or oven cleaner. These prod-
ucts may damage the wheel’s protective finish.
Such damage is not covered by the New Vehicle
Limited Warranty. Only car wash soap, Mopar
Wheel Cleaner or equivalent is recommended.
NOTE:
If you intend parking or storing your vehicle for
an extended period after cleaning the wheels with wheel
cleaner, drive your vehicle and apply the brakes to
remove the water droplets from the brake components.
This activity will remove the red rust on the brake rotors
and prevent vehicle vibration when braking.

Tire Chains (Traction Devices)
Use of traction devices require sufficient tire-to-body
clearance. Follow these recommendations to guard
against damage.
•Traction device must be of proper size for the tire, as
recommended by the traction device manufacturer.
• Install on Rear Tires Only.
• Reduced size snow chains with a maximum projec-
tion of 7 mm beyond the tire profile can be fitted on
vehicles equipped with 235/40 R18 rear tire.
250 SERVICING AND MAINTENANCE

All passenger vehicle tires must conform to Federal
safety requirements in addition to these grades.
Treadwear
The Treadwear grade is a comparative rating, based
on the wear rate of the tire when tested under
controlled conditions on a specified government test
course. For example, a tire graded 150 would wear
one and one-half times as well on the government
course as a tire graded 100. The relative performance
of tires depends upon the actual conditions of their
use, however, and may depart significantly from the
norm due to variations in driving habits, service
practices, and differences in road characteristics and
climate.
Traction Grades
The Traction grades, from highest to lowest, are AA,
A, B, and C. These grades represent the tire’s ability
to stop on wet pavement, as measured under con-
trolled conditions on specified government test sur-
faces of asphalt and concrete. A tire marked C may
have poor traction performance.WARNING!
The traction grade assigned to this tire is based
on straight-ahead braking traction tests, and does
not include acceleration, cornering, hydroplan-
ing, or peak traction characteristics.
Temperature Grades
The Temperature grades are A (the highest), B, and C,
representing the tire’s resistance to the generation of
heat and its ability to dissipate heat, when tested
under controlled conditions on a specified indoor
laboratory test wheel.
Sustained high temperature can cause the material of
the tire to degenerate and reduce tire life, and
excessive temperature can lead to sudden tire failure.
The grade C corresponds to a level of performance,
which all passenger vehicle tires must meet under
the Federal Motor Vehicle Safety Standard No. 109.
Grades B and A represent higher levels of perfor-
mance on the laboratory test wheel, than the mini-
mum required by law.
252 SERVICING AND MAINTENANCE

CAUTION!
•Do not use abrasive or strong cleaning materials
such as steel wool or scouring powder that will
scratch metal and painted surfaces.
• Use of power washers exceeding 1,200 psi
(8 274 kPa) can result in damage or removal of

ers, de-icer salt, etc., be sure that such materials are
well packaged and sealed.
• If a lot of driving is done on gravel roads, consider
mud or stone shields behind each wheel.
• Use Mopar Touch Up Paint on scratches as soon as
possible. Your authorized dealer has touch up paint
to match the color of your vehicle.
