2016 SMART FORTWO wheel size

DOT (Department of Transportation):tire
symbol 0043indicates that the tire complies
with the requirements of the U.S. Department
of Transportation.
Manufacturer identification code: manufac-
turer identification code 0044provides
details on the tire manufacturer. New tires
have a code with two symbols. Retreaded tires
have a code with four symbols.
For further information about retreaded
tires, see (
Ypage 200).
Tire size: identifier 0087describes the tire
size.
Tire type code: tire type code0085can be used
by the manufacturer as a code to describe
specific characteristics of the tire.
Date of manufacture: date of manufacture0083
provides information about the age of a tire.
The first and second positions represent the
week of manufacture, starting with "01" for
the first calendar week. Positions three and
four represent the year of manufacture. For
example, a tire that is marked with "3208",
was manufactured in week 32 in 2008.

Tire characteristics
This information describes the type of tire
cord and the number of layers in sidewall 0043
and under tire tread 0044.

Definition of terms for tires and loading
Tire ply composition and material used
Describes the number of plies or the number
of layers of rubber-coated fabric in the tire
tread and sidewall. These are made of steel,
nylon, polyester and other materials.
Bar
Metric unit for tire pressure. 14.5038 pounds
per square inch (psi) and 100 kilopascals
(kPa) are the equivalent of 1 bar.
DOT (Department of Transportation)
DOT marked tires fulfill the requirements of
the United States Department of Transporta-
tion.
Normal occupant weight
The number of occupants for which the vehicle
is designed multiplied by 68 kilograms
(150 lbs).
Uniform Tire Quality Grading Standards
A uniform standard to grade the quality of
tires with regards to tread quality, tire trac-
tion and temperature characteristics. The
quality grading assessment is made by the
manufacturer following specifications from
the U.S. government. The ratings are molded
into the sidewall of the tire.
Recommended tire pressures
The recommended tire pressure applies to the
tires mounted at the factory.
The Tire and Loading Information placard
contains the recommended tire pressures for
cold tires on a fully loaded vehicle and for
the maximum permissible vehicle speed.
The tire pressure table contains the recom-
mended pressures for cold tires for various
operating conditions, i.e. differing load and
speed conditions.
Increased vehicle weight due to optional
equipment
The combined weight of all standard and
optional equipment available for the vehi-
cle, regardless of whether it is actually
installed on the vehicle or not.
194All about wheels and tires
>> Wheels and tires.

Tread
The part of the tire that comes into contact
with the road.
Bead
The tire bead ensures that the tire sits
securely on the wheel. There are several steel
wires in the bead to prevent the tire from
coming loose from the wheel rim.
Sidewall
The part of the tire between the tread and the
bead.
Weight of optional extras
The combined weight of those optional extras
that weigh more than the replaced standard
parts and more than 5 lbs (2.3 kilograms).
These optional extras, such as high-perform-
ance brakes, level control, a roof rack or a
high-performance battery, are not included
in the curb weight and the weight of the
accessories.
TIN (Tire Identification Number)
This is a unique identifier which can be used
by a tire manufacturer to identify tires, for
example for a product recall, and thus iden-
tify the purchasers. The TIN is made up of the manufacturer's identity code, tire size, tire
type code and the manufacturing date.
Load bearing index
The load bearing index (also load index) is a
code that contains the maximum load bearing
capacity of a tire.
Traction
Traction is the result of friction between the
tires and the road surface.
Treadwear indicators
Narrow bars (tread wear bars) that are dis-
tributed over the tire tread. If the tire tread
is level with the bars, the wear limit of 00CDin
(1.6 mm) has been reached.
Occupant distribution
The distribution of occupants in a vehicle at
their designated seating positions.
Total load limit
Nominal load and luggage load plus 68 kg
(150 lbs) multiplied by the number of seats in
the vehicle.
Changing a wheel
Flat tire
You can find information on what to do in the
event of a flat tire in the "Flat tire" section
(
Ypage 161).
Rotating the wheels
GWARNING
Never interchange the front and rear wheels
as they have different dimensions, e.g.
size, wheel offset etc. Otherwise, there
could be a negative effect on the road hold- ing and you could endanger yourself or oth-
ers.
!On vehicles equipped with a tire pressure
monitor, electronic components are loca-
ted in the wheel.
Tire-mounting tools should not be used
near the valve. This could damage the elec-
tronic components.
Only have tires changed at a qualified spe-
cialist workshop.
Various types of steel wheel can be fitted on
your vehicle. Some steel wheels have a red
mark in the hub cap area. The hub cap has to be
removed to see the red mark, see "Raising the
vehicle" in the "Wheel change" section
(
Ypage 197). When changing the wheels,
always fit wheels of the same type on all axles.
Always pay attention to the instructions and
safety notes when changing a wheel
(
Ypage 196).
The wear patterns on the front and rear tires
differ, depending on the operating condi-
tions. Front tires typically wear more on the
shoulders and the rear tires in the center.
Clean the contact surfaces of the wheel and
the brake disc thoroughly every time a wheel
is rotated. Check the tire pressure and reac-
tivate the tire pressure monitor if necessary.

smart accepts no liability for damage
resulting from the use of tires or wheels
other than those tested and approved.
Information on wheels and tires can be
obtained at a qualified specialist work-
shop, e.g. a smart center.
!Retreaded tires have not been tested by
smart and are not recommended. Previous
damage sustained by the tires (before the
retreading process) cannot always be rec-
ognized. As a result, smart cannot guaran-
tee vehicle safety if retreaded tires are
fitted.
Overview of abbreviations used in the fol-
lowing tire tables:
RBA: both axles
RFA: front axle
RRA: rear axle
The recommended pressures for various oper- ating conditions can be found:
Ron the Tire and Loading Information plac-
ard with the recommended tire pressures on
the B-pillar on the driver's side
Rin the tire pressure table on the inside of
the fuel filler flap
Observe the notes on recommended tire pres-
sures under various operating conditions
(
Ypage 180).
Check tire pressures regularly, and only when
the tires are cold. Comply with the mainte-
nance recommendations of the tire manufac-
turer in the vehicle document wallet.
Notes on the vehicle equipment – always
equip the vehicle with:
Rtires of the same size on a given axle (left/
right)
Rwith the same type of tires on all wheels at a given time (summer tires, winter tires)
Exception: it is permissible to fit a dif-
ferent type or make in the event of a flat
tire.
iThe following pages contain information
on approved wheel rim and tire sizes for
equipping your vehicle with winter tires.
Winter tires are not available at the fac-
tory as standard equipment or optional
extras.
If you want to equip your vehicle with
approved winter tires, it may be necessary
to obtain wheel rims in the corresponding size. The size of the approved winter tires
may differ from the standard tires. This is
dependent on the model and the equipment
installed at the factory.
The tires and wheel rims, as well as further
information, can be obtained at a quali-
fied specialist workshop.
iNot all wheel and tire combinations are
available at the factory for all countries.
