TEMPORARY SPARE TIRES
When using any temporary 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 certies tire manufacturer’s compliance with U.S.
Department of Transportation tire safety standards. Next to the symbol is
the tire identication or “serial number”. The rst two characters identify
the plant where the tire was manufactured. The next two characters
reect 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 year of decade, eg.: 1995, 1985, etc.)
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 consult a qualied tire
technician to determine the year and decade of manufacture.
SERVICE LIFE FOR PASSENGER CAR AND LIGHT
TRUCK TIRES INCLUDING SPARE TIRES
The following recommendation applies to passenger car and light
truck 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, ination 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 specic tire in advance is not possible.
That is why, in addition to regular inspections and ination pressure
maintenance by consumers, it is recommended to have passenger car and
light truck tires, including spare tires, inspected regularly by a qualied
tire specialist, such as a tire dealer, 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 ination 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.
