BFGOODRICH TIRE
Storage
Tires contain materials to protect their outer surfaces from ozone
and weather checking. As the tire rolls and flexes, those materials
continually migrate to the surface, replenishing this protection
throughout the normal use of the tire. Consequently, when tires sit
outdoors, unused for long periods of time (a month or more), their
surfaces become dry and more susceptible to ozone and weather
checking, and the casing becomes susceptible to flat spotting. For
this reason, tires should always be stored in a cool, dry, clean, indoor
environment. If storage is for one month or more, eliminate the weight
from the tires by raising the vehicle or by removing the tires from the \
vehicle. Failure to store tires in accordance with these instructions
could result in damage to your tires or premature aging of the tires
and sudden tire failure. When tires are stored, be sure they are placed \
away from sources of heat and ozone such as hot pipes and electric
generators. Be sure that surfaces on which tires are stored are clean
and free from grease, gasoline or other substances which could
deteriorate the rubber. Tires exposed to these materials during storage
or driving could be subject to sudden failure.
One reason why your spare tire should be included in the tire rotation
schedule is that temperatures in a vehicle’s closed trunk, especially
in sunny geographical areas, can become high enough so that, over
a sustained period, they can cause small cracks or other changes to
the properties of a tire stored in the trunk. An accumulation of such
changes can weaken the tire and, especially if the tire is not kept
properly inflated, make it unsafe to use when it is needed.
Proper Tire Mounting
Tire mounting can be dangerous and must be done by professionally
trained persons using proper tools and procedures as specified by the
U.S. Tire Manufacturers Association.
Your tires should be mounted on wheels that are the correct size
and type and are in good, clean condition. Wheels that are bent,
chipped, rusted (steel wheels) or corroded (alloy wheels) may cause
tire damage. The inside of the tire must be free from foreign material.

24
BFGOODRICH TIRE
Have your tire retailer check the wheels before mounting new tires.
Mismatched tires and rims can explode during mounting. Also,
mismatched tires and rims can result in dangerous tire failure on
the road. If a tire is mounted by error on the wrong-sized rim, do not
remount it on the proper rim – scrap it. It may have been damaged
internally (which is not externally visible) by having been dangerously
stretched and could fail on the highway, resulting in an accident.
Old valves may leak. When new tubeless tires are mounted, have
new valves of the correct type installed. Tubeless tires must be
mounted only on wheels designed for tubeless tires, i.e., wheels that
have safety humps or ledges. Always utilize valve caps capable of
containing the tire’s inflation, should the valve core leak. The valve
cap is the primary seal against air loss. Each tire and wheel assembly
should be balanced to ensure proper tire and vehicle performance and
to maintain tire warranty coverage. Tires and wheel assemblies that
are not balanced may cause steering difficulties, a bumpy ride, and
irregular tire wear.
Temporary Type Spare Tires
When using any temporary type spare tire, be sure to follow the vehicle \
manufacturer’s instructions.
Reading the Dot
DOT XXXX XXXX XXX (prior to August 2000)
DOT XXXX XXXX XXXX (after July 2000)
The Dot
The “DOT” symbol certifies tire manufacturer’s compliance with
U.S. Department of Transportation tire safety standards. Next to
the symbol is the tire identification or “serial number.” The first two
characters identify the plant where the tire was manufactured. The
next two characters reflect the tire size. The following one to four
digits may be used at the tire manufacturer’s option as a descriptive
code. The last three characters are numbers identifying the week and
year of manufacture. (Example: “O25” means second week of the

25
BFGOODRICH TIRE
year of decade, e.g.: 1995, 1985, etc.) For the 1990-1999 decade
BFGOODRICH® brand tires are marked with a triangle pointing to the
last three numeric characters. Tires produced after July 2000 have an
additional digit to identify a given decade. For example, 2800 means
the tire was produced during the 28th week of 2000; 0201 during the
2nd week of 2001. If the last digits of your DOT number contain three
numeric characters and are not marked with a triangle, consult a
qualified tire professional to determine the year of manufacture.
Service Life and Safety for Passenger Car and Light
Truck Tires Including Spare Tires
Tires are composed of various types of material and rubber
compounds having performance properties essential to the proper
functioning of the tire itself. These component properties evolve over
time. For each tire, this evolution depends upon many factors such
as weather, storage conditions, and conditions of use (load, speed,
inflation pressure, maintenance etc.) to which the tire is subjected
throughout its life. This service-related evolution varies widely so that
accurately predicting the serviceable life of any specific tire in advance
is not possible. That is why, in addition to regular inspections and
inflation pressure maintenance by consumers, it is recommended that
passenger car and light truck tires, including spare tires be inspected \
regularly by a qualified tire specialist, such as a BFGoodrich tire
retailer, who will assess the tire’s suitability for continued service.
Tires which have been in use for 5 years or more should continue to
be inspected by a specialist at least annually. Consumers are strongly
encouraged to be aware not only of their tires’ visual condition and
inflation pressure but also of any change in dynamic performance such
as increased air loss, noise or vibration, which could be an indication \
that the tires need to be removed from service to prevent tire failure. \
It
is impossible to predict when tires should be replaced based on their
calendar age alone. However, the older a tire, the greater the chance
that it will need to be replaced due to the service-related evolution or
other conditions found upon inspection or detected during use. While
most tires will need replacement before they achieve 10 years, it is
recommended that any tires in service 10 years or more from the date
of manufacture, including spare tires, be replaced with new tires as
a precaution even if such tires appear serviceable and even if they

26
BFGOODRICH TIRE
have not reached the legal wear limit. For tires that were on an origina\
l
equipment vehicle (i.e., acquired by the consumer on a new vehicle),
follow the vehicle manufacturer’s tire replacement recommendations,
when specified (but not to exceed 10 years). The date when a tire
was manufactured is located on the sidewall of each tire. Consumers
should locate the Department of Transportation or “DOT” code on the
tire. The code begins with “DOT” and ends with the week and year of
manufacture. For example, a DOT code ending with “2214” indicates
a tire made in the 22nd week of 2014.

Tire Inflation Pressure
Tires can lose 1 psi (pound per square inch) per month under
normal conditions. Additionally, tires can lose 1 psi for every 10° F
temperature drop.

Just a look won’t do it. One of these tires is actually 10 psi under-
inflated. Your eyes can deceive you, so rely on a good tire gauge for
an accurate reading.

Look for the manufacturer’s recommended tire pressure listed on
the sticker usually located on the driver’s-side door edge or door
jamb area. Example:

This chart shows you how underinflation can create an overload
on tires. Check your tire pressure every month to make sure it’s up to
specification, especially before long trips or carrying extra weight.
Lower pressure increases heat. Infrared photography of tires tested at

Air Pressure—Monthly Check
For accuracy, check your inflation pressure with a tire gauge
when tires are cold.
Driving heats up tires and makes the reading incorrect.a.
