Uniform
Tire
Quality
Grading
is
a
tire
information
system
devel-
oped
by
the
United
States
Nation-
al
Highway
Traffic
Safety
Adminis-
tration
(NHTSA)
that
is
designed
to
help
buyers
make
relative
com-
parisons
among
tires.
The
UTQG
is
not
a
safety
rating
and
not
a
guar-
antee
that
a
tire
will last
for
a
prescribed
number
of
miles
(kilo-
meters)
or
perform
in
a
certain
way.
It
simply
gives
tire
buyers
additional
information
to
com-
bine
with
other
considerations,
such
as
price,
brand
loyalty
and
dealer
recommendations.
Under
UTQG,
tires
are
graded
by
the
tire
manufacturers
in
three
areas:
treadwear,
traction,
and
tempera-
ture
resistance.
The
UTQG
infor-
mation
on
the
tires,
molded
into
the
sidewalls.
U.S.
DOT
Tire
Identification
Number
(TIN)
This
is
the
tire’s
“serial
number”.
It
begins
with
the letters
“DOT”
and
indicates
that
the
tire
meets
all
federal
standards.
The
next
two
numbers
or
letters
indicate
the
plant
where
it
was
manufac-
tured,
and
the
last
four
numbers
represent
the
week
and
year
of
manufacture.
For
example,
DOT...
2219...
means
that
the
tire
was
produced
in
the
22nd
week
of
2019.
The
other
numbers
are
marketing
co-
des
that
may
or
may
not
be
used
