10. Pirelli Sensorized Tires
The sensorized tire provides specific data to a selected vehicle manufacturer’s onboard
computer system designed to work with Pirelli sensorized tires. It is important the care is used
during mounting and demounting to avoid damage to the sensor.
If sensorized tires are stored off the vehicle during seasonal changes, the fitted unit must be
stored in a stack, inflated at a maximum pressure of 1.5 bar (21.75 psi) to preserve the sensor
battery life.
Warning: It is essential to inflate sensorized tires to placard pressure before returning
tires to service.
Pirelli sensorized tires should be returned to authorized dealers at end of life so that the sensor
and the tire can be recycled properly.
11. Elect
The Elect marking on a Pirelli tire sidewall identifies tires developed to meet the specific
technical requirements of electric and plug-in hybrid vehicles.
12. 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 rating) as found on the vehicle placard or in the
owner’s manual should always be followed when replacing tires. It is important that TPMS
functionality be confirmed each time a tire is replaced if applicable. Sensorized tires must be
replaced with Pirelli equivalent sensorized tires that communicate with the select vehicle
onboard computer system to properly provide the designed functionality by the vehicle
Manufacturers. 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, 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:
