Lincoln Aviator: Tire Care / Information on T Type Tires
T145/80D16 is an example of a tire size.
Note: The temporary tire size for your
vehicle may be different from this
example. Tire Quality Grades do not
apply to this type of tire.

T type tires have some additional
information beyond those of P type tires;
these differences are described below:
- T: Indicates a type of tire, designated
by the Tire and Rim Association, that is
intended for temporary service on cars,
sport utility vehicles, minivans and light
trucks.
- 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.
- 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: Indicates a diagonal type tire.
R: Indicates a radial
type tire.
- 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.
Note: Tire Quality Grades do not apply
to this type of tire.

Safe operation of your vehicle requires
