Information on “T” type tires
“T” type tires have some additional information beyond those of “P” type tires; these differences are described below:
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.
1. T: Indicates a type of tire,
designated by the Tire and Rim
Association (T&RA), that is
intended for temporary service on
cars, SUVs, minivans and light
trucks.
2. 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.
3. 80: Indicates the aspect ratio which gives the tire’s ratio of height
to
width. Numbers of 70 or lower indicate a short sidewall.
4. D: Indicates a “diagonal” type tire.
R: Indicates a “radial” type tire.
5. 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.
