temporary service on cars, sport
utility vehicles, minivans and light
trucks.
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.

height to width. Numbers of 70 or
lower indicate a short sidewall.
D. D: Indicates a diagonal type tire.
