B. 145: 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. 80: Indicates the aspect ratio
which gives the tire's ratio of height to
width. Numbers of 70 or lower
indicate a short sidewall.
D. D: Indicates a diagonal type tire.
R: Indicates a radial type tire.
E. 16: Indicates the wheel or rim
diameter in inches. If you change your
wheel size, you will have to purchase
new tires to match the new wheel
diameter.
Location of the Tire Label
You will find a Tire Label containing
tire inflation pressure by tire size and
other important information located
on the B-Pillar or the edge of the
driver's door.
Inflating Your Tires
Safe operation of your vehicle requires
that your tires are properly inflated.
Remember that a tire can lose up to
half of its air pressure without
appearing flat.
Every day before you drive, check your
tires. If one looks lower than the
others, use a tire gauge to check
pressure of all tires and adjust if
required.
