Note:
For tires with a maximum
speed capability over 149 mph
(240 km/h), tire manufacturers
sometimes use the letters ZR. For
those with a maximum speed
capability over 186 mph (299
km/h), tire manufacturers always
use the letters ZR.
Note:
If the tire size does not begin
with a letter, this may mean it is
designated by either ETRTO
(European Tire and Rim Technical
Organization) or JATMA (Japan Tire
Manufacturing Association). You
may not find this information on all
tires because it is not required by
federal law.
Note:
The tire suppliers may have
additional markings, notes or
warnings, for example standard
load, radial tubeless, etc.
T Type Tires

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.
