Tires and wheels
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.
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.
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
1
than / in (3 mm).
