FORD 2013 Expedition v.2 - Manual (Page 335)

INFORMATION CONTAINED ON THE TIRE SIDEWALL
Both U.S. and Canada Federal regulations require tire manufacturers to
place standardized information on the sidewall of all tires. This
information identifies and describes the fundamental characteristics of
the tire and also provides a U.S. DOT Tire Identification Number for
safety standard certification and in case of a recall.
Information on P Type Tires
P215/65R15 95H is an example of a
tire size, load index and speed
rating. The definitions of these
items are listed below. (Note that
the tire size, load index and speed
rating for your vehicle may be
different from this example.)
A. P: Indicates a tire, designated by the Tire and Rim Association
(T&RA), that may be used for service on cars, sport utility vehicles,
minivans and light trucks.
Note: If your tire size does not begin with a letter, this may mean it is
designated by either ETRTO (European Tire and Rim Technical
Organization) or JATMA (Japan Tire Manufacturing Association).
B. 215: Indicates the nominal width of the tire in millimeters from
sidewall edge to sidewall edge. In general, the larger the number, the
wider the tire.
C. 65: Indicates the aspect ratio which gives the tire’s ratio of height to
width.
D. R: Indicates a radial type tire.
