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 check interchangeability to maintain proper vehicle dynamics.
Please be aware that it is important, before fitting the suggested tires, to confirm that the fitment
is allowed by the technical specifications of the vehicle, the vehicle manufacturer and the
relevant homologations. Pirelli 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 VEHICLE DYNAMICS AND LOAD CARRYING CAPACITY, REPLACEMENT
TIRES MUST ALWAYS HAVE A LOAD INDEX AND SPEED SYMBOL EQUAL TO OR
GREATER THAN THOSE FITTED AS ORIGINAL EQUIPMENT.
When installing plus size fitments, you should consult with the dealer regarding any suspension
or braking system modifications which may be recommended for the vehicle.
Tires taken out of service should be recycled properly through an authorized dealer or tire
recycling service provider.
13. Tire Inspection
As a minimum, tires 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 dealer to determine proper action – this includes but not limited to tires
with Run Flat, and Seal Inside technology. Pirelli tires have treadwear indicators in the tread
grooves, which clearly show when the tread has worn to 2/32” remaining. At this point, your tires
must be replaced because they do not meet the federal minimum tread depth and they may be
dangerous if left in service.
Tires should be removed from service for numerous reasons, including tread worn down to
minimum depth, damage or abuse (including, without limitation, punctures, cuts, impacts,
cracks, bulges, under inflation, overloading, etc.). For these reasons, tires, including spares,
should be inspected at least once a month and before long trips. Inspection should occur
regardless of whether the vehicle is equipped with a tire pressure monitoring system. In
addition to these visual conditions, consumers should take note of and address any change in
performance such as increased air loss, noise or vibration or other factors.
The mere passage of time (age) does not cause tires to deteriorate, but rather exposure to
outside forces. The service life of a tire is a function of service and storage conditions. For each
individual tire, this service life is determined by many factors such as temperature/weather,
storage conditions, and service conditions (e.g., load, speed, inflation pressure, maintenance,
and road hazard damage, etc.) to which a tire is subjected throughout its life. Since service and
storage conditions vary widely, accurately predicting the service life of any specific tire based on
chronological age is not possible. There is no scientific or technical data that establishes or
identifies a minimum or maximum service life, but the longer a tire has been in service, the
greater the chance that it will need to be replaced due to service-related conditions.
