2010 SMART FORTWO COUPE wheel size

smart recommends winter tires
( Y page 132) with a minimum tread depth of
approximately 1
/ 6 in (4 mm) on all four
wheels for the winter season to ensure
normal balanced handling characteristics.
On packed snow, they can reduce your
stopping distance compared to summer
tires.
Stopping distance, however, is still
considerably greater than when the road is
not covered with snow or ice. Exercise
appropriate caution.
! Avoid spinning of a drive wheel for an
extended period when driving off on
slippery road surfaces. Otherwise, the
drivetrain could be damaged, which is
not covered by the smart Limited
Warranty.
Tire speed rating
Regardless of the tire speed rating, local
speed limits should be obeyed. Use prudent
driving speeds appropriate to prevailing
conditions.
GWarning!
Even when permitted by law, never operate
a vehicle at speeds greater than the
maximum speed rating of the tires.
Exceeding the maximum speed for which
tires are rated can lead to sudden tire
failure, causing loss of vehicle control and
possibly resulting in an accident and/or
personal injury and possible death, for you
and for others.
An electronic speed limiter prevents your
vehicle from exceeding a speed of 90 mph
(145 km/h).
The factory equipped tires on your vehicle
may have a tire speed rating above the
maximum speed permitted by the
electronic speed limiter.
Make sure your tires have the required tire
speed rating as specified for your vehicle
in the “Technical data section”
( Y page 202), for example when purchasing
new tires.
For information on how to identify the tire
speed rating on a tire’s sidewall, see “Tire
size designation, load and speed rating”
( Y page 126).
If you are uncertain about the correct
reading of the information given on a
tire’s sidewall, any authorized smart
center will be glad to assist you.
i For information on speed ratings for
winter tires, see “All-season and winter
tires” ( Y page 127).
Winter driving instructions
The most important rule for slippery or icy
roads is to drive sensibly and to avoid
abrupt acceleration, braking and steering
maneuvers.
When the vehicle is in danger of skidding,
move gear selector lever to neutral
position N. Try to keep the vehicle under
control by corrective steering action.
For information on driving with snow
chains*, see “Snow chains*” ( Y page 133).
GWarning!
On slippery road surfaces, never downshift
in order to obtain braking action. This
could result in drive wheel slip and
reduced vehicle control. Your vehicle’s ABS
will not prevent this type of loss of control.
Road salts and chemicals can adversely
affect braking efficiency. Increased pedal
force may become necessary to produce the
normal braking effect.
Depressing the brake pedal periodically
when traveling at length on salt-strewn
roads can bring road-salt-impaired
braking efficiency back to normal.
If the vehicle is parked after being driven
on salt-treated roads, the braking

adversely affect handling and fuel
economy, and are more likely to fail from
being overheated.
Do not overinflate tires. Overinflated
tires can adversely affect handling and
ride comfort, wear unevenly, increase
stopping distance, and result in sudden
deflation (blowout) because they are more
likely to become punctured or damaged by
road debris, potholes etc.
Do not overload the tires by exceeding the
specified load limit as indicated on the
Tire and Loading Information placard on
the driver’s door B‑pillar. Overloading the
tires can overheat them, possibly causing
a blowout. Overloading the tires can also
result in handling or steering problems, or
brake failure.XDrive to the nearest authorized smart
center, to have the damaged tire
replaced.XContact an authorized smart center as
soon as possible to obtain a new filler
hose and a new tire sealant container.XBring used tire sealant materials to an
authorized smart center for proper
disposal.XReplace your tire sealant container
every 4 years. Replacement containers
are available at any authorized smart
center.GWarning!
After changing a tire, contact a smart
center to make sure the bolts holding the
wheel to the car are tight enough.
Otherwise, the wheels could come off. Each
bolt should be tightened to a torque of
81 lb‑ft (110 Nm).
Wheel change
Preparing the vehicle
XPark the vehicle on a hard, flat surface
when possible.XTurn on the hazard warning flasher.XTurn the steering wheel so that the front
wheels are in a straight-ahead position.XEngage the parking brake.XMove the gear selector lever to park
position P.XTurn off the engine.XHave any passenger exit the vehicle at a
safe distance from the roadway.
Removing the wheel
GWarning!
When jacking up the vehicle, only use a
suitable jack. Observe the manufacturer’s
safety instructions.
The jack must be designed for jacking up
this vehicle at the jack take-up brackets
built into both sides of the vehicle.
The jack is intended only for lifting the
vehicle briefly for wheel changes. It is not
suited for performing maintenance work
under the vehicle. To help avoid personal
injury, use the jack only to lift the vehicle
during a wheel change.
Never get beneath the vehicle while it is
supported by the jack. Keep hands and feet
away from the area under the lifted vehicle.
Always lower the vehicle onto sufficient
capacity jackstands before working under
the vehicle.
Always firmly engage the parking brake and
block the wheels with wheel chocks or other
sizeable objects before raising the
vehicle with the jack. Do not release the
parking brake while the vehicle is raised.
Make sure the ground on which the vehicle
is standing and where you place the jack is

solid, level and not slippery. If necessary,
use a large underlay. On slippery surfaces,
such as tiled floors, you should use a non-
slip underlay, for example a rubber mat.
Do not use wooden blocks or similar objects
to support the jack. Otherwise the jack may
not be able to achieve its load-bearing
capacity if it is not at its full height.
The jack must always be vertical when in
use. Always try to use the jack on level
surface. If you do not position the jack
correctly, the vehicle can fall off the jack
and seriously or fatally injure you or
others.
Never start the engine when the vehicle is
raised.
Also observe the notes on the jack.XMake sure to have a suitable jack 17
, wheel
wrench 17
and wheel chock 17
.
Contact an authorized smart center for
information on which jack and wheel
wrench are required.XPrepare the vehicle as described
( Y page 177).XMake sure the surface is level.
Prevent the vehicle from rolling away by
blocking wheels with wheel chocks or other
sizeable objects:
XPlace one wheel chock or other sizeable
object in front of and another wheel
chock or other sizeable object behind
the wheel that is diagonally opposite to
the wheel being changed.
Steel rim with wheel cover
XVehicles with wheel cover on steel rim:
Pull the wheel cover off of the rim.
If necessary, use a suitable tool to pry
the wheel cover off.XOn wheel to be changed, loosen but do not
yet remove the wheel bolts
(approximately one full turn with wheel
wrench).
Steel rim with wheel trim cap
XVehicles with wheel trim cap on steel
rim: On wheel to be changed, loosen but
do not yet remove the wheel bolts
(approximately one full turn with wheel
wrench).XTake the wheel trim cap off.17 Not included and not available as factory equipment.178Wheel change>> Practical hints.
