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.
