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 unap-
proved 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 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 (four 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
the 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: 225/
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 tires,
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 combina-
tion with the technical specifications for the chassis and vehicle.
