>> Operation Contact an authorized smart center for infor

mation on tested and recommended rims and
tires for summer and winter operation. They
can also offer advice concerning tire service
and purchase.
Modifications to the brake system and wheels
and the use of spacer and brake dust rings
are not permissible.
Important guidelines• Only use sets of tires and rims of the same
type and make.
• Tires must be of the correct size for the
rim.
• Break in new tires for approximately
60 miles (100 km) at moderate speeds.
• Regularly check the tires and rims for
damage. Dented or bent rims can cause tire
inflation pressure loss and damage to the
tire beads.
• If vehicle is heavily loaded, check tire infla

tion pressure and correct as required.
• Do not allow your tires to wear down too far.
Adhesion properties on wet roads are
sharply reduced at tread depths of less
than
1/8in (3 mm).
G
Warning!
Replace rims or tires with the same des

ignation, manufacturer and type as shown
on the original part. Contact an autho

rized smart center for further informa

tion. If incorrectly sized rims and tires
are mounted:
• The wheel brakes or suspension
components can be damaged.
• The operating clearance of the wheels
and the tires may no longer be correct.
G
Warning!
Worn, old tires can cause accidents. If the
tire tread is badly worn, or if the tires
have sustained damage, replace them.
When replacing rims, only use genuine
smart wheel bolts specified for the
particular rim type. Failure to do so can
result in the bolts loosening and possibly
an accident.
Retreaded tires are not tested or recom

mended by smart, since previous damage
cannot always be recognized on retreads.
The operating safety of the vehicle can

not be assured when such tires are used.

General:
Depending on the design standards used, the
tire size molded into the sidewall may have no
letter or a letter preceding the tire size des

ignation.
No letter preceding the size designation
(as illustrated above): Passenger car tire
based on European design standards.
Letter "P" preceding the size designation:
Passenger car tire based on U.S. design
standards.
Letter "LT" preceding the size designation:
Light Truck tire based on U.S. design
standards.
Letter "T" preceding the size designation:
Temporary spare tires which are high
pressure compact spares designed for
temporary emergency use only.
Tire width
Tire width1
(
page 196) indicates the
nominal tire width in mm.Aspect ratio
Aspect ratio2
(
page 196) is the dimen

sional relationship between tire section
height and section width and is expressed in
percentage. The aspect ratio is arrived at by
dividing section height by section width.
Tire code
Tire code3 (

page 196) indicates the tire
construction type. The "R" stands for radial
tire type. Letter "D" means diagonal or bias
ply construction; letter "B" means belted

bias ply construction.
At the tire manufacturer’s option, any tire
with a speed capability above 149 mph
(240 km/h) can include a "ZR" in the size
designation (for example: 245/40 ZR 18).
For additional information, see "Tire speed
rating" (

page 198)
.
Rim diameter
Rim diameter4 (

page 196) is the diameter
of the bead seat, not the diameter of the rim
edge. Rim diameter is indicated in inches (in).Tire load rating
Tire load rating5 (

page 196) is a numeri

cal code associated with the maximum load a
tire can support.
For example, a load rating of 91 corresponds
to a maximum load of 1 356 lbs (615 kg) the
tire is designed to support.
See also "Maximum tire load" (

page 201)
where the maximum load associated with the
load index is indicated in kilograms and lbs.
G
Warning!
The tire load rating must always be at
least half of the GAWR (

page 205) of
your vehicle. Otherwise, tire failure may
result and cause an accident and/or seri

ous personal injury to you or others.
Always replace rims and tires with the
same designation, manufacturer and type
as shown on the original part.

Tires and wheels
>> Operation
207
Uniform Tire Quality Grading Standards
A tire information system that provides
consumers with ratings for a tire’s traction,
temperature and treadwear. Ratings are
determined by tire manufacturers using
government testing procedures. The ratings
are molded into the sidewall of the tire.
Vehicle maximum load on the tire
Load on an individual tire that is determined
by distributing to each axle its share of the
maximum loaded vehicle weight and dividing it
by two.
Rotating tiresThoroughly clean the mounting face of the
wheels and brake disks, i.e. the inner side of
the wheels/tires each time the wheels/tires
are changed. Check for and ensure proper
tire inflation pressure.For information on wheel change, see "Flat
tire" (

page 265).
G
Warning!
Do not rotate front and rear wheels as
they have different dimensions, e.g. rim
size, wheel offset etc. Otherwise, the
handling can be affected and you could
endanger yourself and others.
G
Warning!
Have the tightening torque checked after
changing a wheel. Wheels could become
loose if not tightened with a torque of
81 lb
ft (110 Nm).
Only use genuine smart wheel bolts
specified for your vehicle’s rims.

>> Technical data.
!
Only use tires which have been tested and
approved by smart. Tires approved by smart
are developed to provide best possible
performance in conjunction with the driving
safety systems on your vehicle such as ABS
or ESP
®.
Using tires other than those approved by
smart may result in damage that is not
covered by the smart Limited Warranty.
!
Using tires other than those approved by
smart can have detrimental effects, such as
• poor handling characteristics
• increased noise
• increased fuel consumption
Moreover, tires and rims not approved by
smart may, under load, exhibit dimensional
variations and different tire deformation
characteristics that could cause them to come
into contact with the vehicle body or axle
parts. Damage to the tires or the vehicle may
be the result.
i
Further information on tires and rims is
available at any authorized smart center.
A placard with the recommended tire inflation
pressure is located on the driver’s door
B
pillar (

page 185).
The tire inflation pressure should be checked
regularly and should only be adjusted on cold
tires. Follow tire manufacturer’s maintenance
recommendation included with vehicle.
