WARNING!
The wet performance (aquaplaning
resistance) will decrease
proportionally to the thickness of the
tread.
Tires Durability
The service life of a tire depends on
various factors including, but not
limited to:
• driving style;
• tire pressure;
• distance driven.
WARNING!
Tires and the spare tire (if equipped)
should be replaced after six years,
regardless of the remaining tread.
Failure to follow this warning could
result in tire failure.
Replacement Tires
NOTE:
In order to maintain high performance
and safety level under all driving
conditions, Maserati strongly
recommends to use tires equivalent to
the originals in size, quality and
performance when replacement is
needed.
For the size designation of your tire
see the label on the driver's side rear
door pillar or see table “Wheels” in
section “Features and Specifications”.
The “Load Index” and “Speed Symbol”
for your tire will be found on the
original equipment tire sidewall.
It is recommended to replace the two
front tires or two rear tires as a pair.
Replacing just one tire can seriously
affect your vehicle’s handling.
If you ever replace a wheel assembly,
make sure that the wheel’s
specifications (valve, TPMS sensor and
tire) match those of the original
wheels. Failure to use equivalent
replacement tires may adversely affect
the safety, handling, and ride of your
vehicle.
YourAuthorized Maserati Dealeris
available to provide suggestions as tothe types of tires most suited to the
use foreseen by the Customer.
WARNING!
•Do not use a tire, wheel size or
rating other than that specified for
your vehicle. Some combinations of
unapproved tires and wheels may
change suspension dimensions and
performance characteristics,
resulting in altered steering,
handling, and braking operations of
the vehicle. This can cause
unpredictable handling and stress to
steering and suspension
components. Use only the tire and
wheel sizes with load ratings
appointed for your vehicle.
•Never use a tire with a smaller load
index or capacity, other than what
was originally equipped on your
vehicle. Using a tire with a smaller
load index could result in tire
overloading and failure.
•Always check the maximum speed
rating on the tire sidewall on any
tire on the vehicle.
