Tire care
Wear indicators are molded into
the bottom of the tread grooves at
intervals around the tire, indicated
by small pointers on the outer tread
blocks. The tires should be replaced
before being worn to this minimum
legal tread depth.
The cold tire pressures should be
checked every week, or every 1000
miles (1700 km), whichever is the
sooner, and corrections made as
necessary. See ‘Technical Data’ at
the back of the handbook for tire
pressures. Underinflation will cause
excessive wear, rapid deterioration of
the tire sidewalls and heavy steering,
whereas overinflation results in a
hard ride and in creased susceptibility
to tire damage. Both conditions will
cause a degradation in the handling
qualities.
Vehicle load limits:
Federal regulations require the
following statement in this manual:
“Steps for Determining Correct Load
Limit“
1) Locate the statement “The
combined weight of occupants and
cargo should never exceed XXX
kg or XXX lbs.” on your vehicle’s
placard.
2) Determine the combined weight of
the driver and passengers that will
be riding in your vehicle.
3) Subtract the combined weight of
the driver and passengers from XXX
kg or XXX lbs.
4) The resulting figure equals the
available amount of cargo and
luggage load capacity. For example,
if the “XXX” amount equals 1400
lbs. and there will be five 150 lb
passengers in your vehicle, the
amount of available cargo and
luggage load capacity is 650 lbs.
(1400-750 (5 x 150) = 650 lbs.)
5) Determine the combined weight of
luggage and cargo being loaded
on the vehicle. That weight may
not safely exceed the available
cargo and luggage load capacity
calculated in Step 4.
NOTE: The vehicle should not be used
to tow a trailer.
Winter tires
These tires are specially designed for
driving on snow and ice and should
be fitted to replace the ones supplied
with the vehicle.
Only use winter tires having
the same dimensions as
those provided with the
vehicle or as indicated on page 205.
Your Authorized Maserati Dealer is
available to provide suggestions as to
the types of tires most suited to the
use foreseen by the Customer.
For the type of tires to use, inflation
pressures and relative specifications
for winter tires, carefully follow
the indications found in the
section “Capacities and technical
specifications”.
The features of these winter tires are
strongly reduced if the tread depth
is less than 0.2 in (4 mm). In this case,
they should be replaced.
