PIRELLI TIRES

8. Tire Replacement
The tires fitted to your vehicle as original equipment were tested and
ap
proved 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
w i
th the same tread 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
(f
our tires of the same 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 of four.
When replacing tires on light truck vehicles, you should always follow
th
e vehicle manufacturer’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:
22
5/45R17) tires have 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
ti
res, the fitment is allowed 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.
