General: depending on the manufacturer's
standards, the size imprinted in the tire wall
may not contain any letters or may contain one
letter that precedes the size description.
If there is no letter preceding the size
description (as shown above): these are
passenger vehicle tires according to Euro-
pean manufacturing standards.
If "P" precedes the size description: these
are passenger vehicle tires according to U.S.
manufacturing standards.
If "LT" precedes the size description: these
are light truck tires according to U.S. man-
ufacturing standards.
If "T" precedes the size description: compact
emergency wheels with high tire pressure
that are only designed for temporary use in an
emergency.
Tire width: tire width : shows the nominal
tire width in millimeters.
Height-width ratio: aspect ratio ; is the
size ratio between the tire height and tire
width and is shown in percent. The aspect
ratio is calculated by dividing the tire width
by the tire height.
Tire code: tire code = specifies the tire
type. "R" represents radial tires; "D" repre-
sents diagonal tires; "B" represents diago-
nal radial tires.
