Tires
Tire inflation pressure when cold
The tire inflation values, indicated in
this manual, are intended for cold tires.
The maximum speed that can
be reached with winter tires is
indicated by the tire
manufacturer. Always comply with the
local regulations.
When using the spare wheel
(emergency wheel) do not
exceed 50 mph (80 km/h).
Avoid driving at full throttle, braking
sharply and cornering at high speeds.
Uniform Tire Quality Grading
All passenger car tires must conform to
Federal Safety requirements in addition
to these grades.
DOT Quality Grades
Treadwear
The treadwear grade is a comparative
rating based on the wear rate of the
tire when tested under controlled
conditions on a specified government
test course.
For example, a tire graded 150 would
wear one and one-half (1
1
/
2
) times as
well on the government course as a
tire graded 100.
The relative performance of tires
depends upon the actual conditions of
their use, however, and may depart
significantly from the norm due to
variations in driving habits, service
practices and differences in road
characteristics and climate.
Traction
The traction grades, from highset to
lowest, are “AA”, “A”, “B”, and “C”.
Those grades represent the tire’s
ability to stop on wet pavement as
measured under controlled conditions
on specified government test surfaces
of asphalt and concrete.
The traction grade assigned to
this tire is based on straight-
ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning, or peak
traction characteristics
