8. Tire Replacement
The tires fitted to your vehicle as original equipment were tested and approved by the
vehicle manufacturer and the tire manufacturer and take into account all aspects of the
vehicle’s operation. Changes in the tire size, type or construction should not be made
without seeking advice from the vehicle or tire manufacturer or an authorized Pirelli
dealer since unapproved tires on your vehicle could adversely affect steering, handling,
braking and traction. The tire information (tire size, load index and speed symbol) as
found on the vehicle placard or in the owner’s manual should always be followed when
replacing tires.
It is strongly recommended that Pirelli tires be mounted in sets of four with the same
t r
ead type. Pirelli tires should not be mixed with other tire brands. It is necessary to follow
this procedure because different tire constructions have different handling
characteristics. Tires on the same axle must be the same manufacturer, brand, tire size,
load index, speed rating and Pirelli part number.
When changing only two tires on a vehicle which is homogeneously fitted (four tires of the
sa
me tire size), fit the new tires on the rear axle. This applies to all vehicles regardless of
their drive axle. (Front or Rear Drive).
On all wheel drive or four wheel drive vehicles the tires must always be replaced in sets
o f
four.
When replacing tires on light truck vehicles, you should always follow the vehicle
m a
nufacturer’s recommendations. Passenger and light truck tires are not
interchangeable, due to differences in their pressures and load carrying capacity.
P-Metric and Euro-metric Interchangeability: Euro-metric (Example: 225/45R17) tires
h a
ve a load index which is equal to or greater than that of the same size P-metric
(Example: P225/45R17) tire. Therefore, they have the same or higher load carrying
capacity at the maximum rated inflation pressure. Always check with your tire dealer or
Pirelli Tire Consumer Affairs to be sure of the exact interchangeability to maintain proper
vehicle dynamics.
Please be aware that it is important that, before fitting the suggested tires, the fitment is
a l
lowed by the technical specifications of the vehicle, the vehicle manufacturer and the
relevant homologations. Pirelli Tire does not express any view as to the compatibility of
the wheel/tire combination with the technical specifications for the chassis and vehicle.
TO MAINTAIN PROPER VEHICLE DYNAMICS AND LOAD CARRYING CAPACITY,
R E
PLACEMENT TIRES MUST ALWAYS HAVE A LOAD INDEX AND SPEED SYMBOL EQUAL
TO OR GREATER THAN THOSE FITTED AS ORIGINAL EQUIPMENT.
When making plus size fitments, you should consult with the dealer regarding any
s u
spension or braking system modifications which may be recommended for the vehicle.
9. Tire Inspection
As a minimum, tires (including the spare tire) should be examined and air pressure
checked monthly and always prior to long trips. They should also be examined if you
strike any unusual object on the road. Tires showing bulges, cracks, cuts, penetrations
or uneven wear must be dismounted and examined by an authorized Pirelli tire dealer
