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.

TO MAINTAIN PROPER 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 making plus size fitments, you should consult with the dealer
re
garding any suspension 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
an
d 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 and
replaced if necessary. Pirelli tires have treadwear indicators in the
tread grooves, which show up when the tread has worn to 2/32”
remaining. At this point, your tires must be replaced because they are
illegal and dangerous.
The mere passage of time (age) does not cause tires to deteriorate, but
ra
ther exposure to outside forces. Such outside forces can include, but
are not limited to: road hazards, punctures, improper repairs,
misalignment, under inflated operation, over inflated operation,
excessive heat caused by over deflected operation, excessive exposure
to ozone, improper storage conditions, etc. Tire companies can only
have an impact on a few of these exposures. Tire companies add
antiozinants and anti-oxidants (anti-degradation compounds) to
minimize degradation. Pirelli believes that since there is no way to
accurately predict what outside forces a tire will be exposed to there is
no scientifically supportable age limit that can be set for tires.
To avoid cosmetic damage, use a mild soap solution to clean sidewalls
a n
d rinse off with low-pressure tap water. Never apply cleaners or
dressings to enhance sidewall appearance to avoid removal of
antioxidants, which are intended to prevent ozone degradation. The
removal of anti-oxidants may degrade the rubber and can lead to
sidewall cracking. Use of high-pressure sprayers may cause sidewall
damage.
WARNING!
Driving on a damaged tire is dangerous, as the tire can suddenly
fa
il, which can lead to an accident and serious personal injury or
death.

Toyo Tires speed-rated passenger car tires may be repaired and
returned to service under the following conditions:
• Proper repair materials and procedures have been used.
•
The damage or puncture is not larger than 1/4” (6.4
mm) in diam-
eter.
• The repair will be the first repair performed on that tire. (Only one
r
epair per tire is permitted in order to maintain a limited speed
rating.)
• The tire must have more than 2/32” (1.6
mm) of tread remaining.
Toyo Tires speed-rated passenger tires that have been properly
re
paired qualify for reduced speed ratings as follows:
The maximum speed of a vehicle is limited by the lowest-speed- rated
ti
re on the car.
PROPER SELECTION OF TIRES
When tires need to be replaced, do not guess what tire is right for your
v e
hicle. First look at the vehicle Owner’s Manual or the Tire
Information Placard. They tell you the size of the tires that were on the
vehicle as original equipment.
Replacement tires for any vehicle must be of a size, load range, and
lo
ad capacity (by inflation) that is capable of supporting the same load
as the vehicle’s Original Equipment (OE) installed tires. Avoid
installing used tires on a vehicle. There is no way to determine what
road hazards or abuse a previously owned tire may have incurred.

CAUTION!
A tire’s speed rating is void if the tire has been retreaded,
da
maged, abused, or otherwise altered from its original condition.
Thereafter, it should be treated as a non-speed-rated tire. In
addition, retreaded passenger and light truck tires are not
warranted by Toyo Tires for any reason. Toyo Tires speed ratings
are voided for retreaded tires.

The following procedures concerning replacement tires must be
followed:
• Confirm that the load-carrying capacity is greater than or equal to
t
he loadcarying capacity of the OE tire size at the pressure indicated
on the vehicle Tire Information Placard.
• Carefully note any differences between recommendations for front
a
nd rear axle positions regarding the tire size and/or inflation pres-
sure.
• The speed rating must be equal to or greater than what is specified
b
y the vehicle manufacturer if the speed capability of the vehicle is
to be maintained.
• Tires should be mounted on approved wheel widths. If changing
t
ire sizes, check to make sure the wheel has adequate load and infla -
tion pressure capacity.
• Body and chassis clearance must be checked on the vehicle’s front
a
nd rear axles.
In addition to the above, light truck tire replacements should take into
co
nsideration the following:
• Proper spacing between dual tires is necessary for optimum tire
p
erformance. If chains are used, particular care must be taken to
assure adequate clearance between loaded tires to avoid damage
from the chains. The allowable outside diameter difference between
a tire and its dual mate is 1/4 inch (6.4 mm) for light truck tires.
WARNING!
• Failure to install tires with adequate load capacity will result in
t
ire fatigue and sudden tire failure. This could lead to loss of
vehicle control, possibly resulting in personal injury or death.
• Certain vehicle performance parameters, including ride comfort
a
nd handling, may be affected by substitute tire sizes. In some
cases, particularly for SUVs and light trucks, a failure to follow
the vehicle manufacturer’s recommendations for tire replace -
ment could adversely affect the safe handling of the vehicle,
po
ssibly resulting in a loss of vehicle control leading to personal
injury or death.

Tire installers should exercise extreme caution when replacing tires on
light trucks.
The maximum load capacity stamped on the sidewall of a P-metric tire
is
reduced by a factor of 1.1 when used on a light truck, a sport utility
vehicle, or a trailer.
When a P-metric or metric tire is installed on a light truck (SUV,
p i
ckup, minivan), the load rating is reduced by dividing by 1.1. (This
load reduction factor is prescribed by Federal Motor Vehicle Safety
Standards (FMVSS) and is based on the expectation that
passenger-type tires may experience more severe loading and usage
conditions when applied to light trucks.) For example, 305/50R20 has
a maximum load capacity of 3086 lbs. If this tire is fitted to a light
truck, the actual allowable load for the tire is 2805 lbs. (3086 lbs.
divided by 1.1).

WARNING!
• P-metric and LT-metric tires are not necessarily interchangeable.
P
-metric and LT-metric tires follow completely different Load/
Inflation tables and are designed to carry different loads at
different pressures.
• LT-metric tires carry their load at higher inflation pressures and
d
o not always have adequate load capacity to replace P-metric
tires of the same size.
• After reducing a P-metric tire’s load rating by dividing by 1.1 for
f
itment on a Light Truck, the P-metric tire may not offer suffi -
cient load capacity to replace an LT-metric tire of the same size.
• Contact your Toyo Tires dealer or Toyo Tires Technical Service
f
or help determining how to choose a proper replacement size.
• Driving with underinflated or overloaded tires may result in
i
mmediate tire failure, which can cause an accident and could
lead to serious personal injury or death.
