TIRE CARE
Important information for 245/40R19
low-profile tires and wheels If your
vehicle is equipped with 245/40R19
tires, they are low-profile tires. These
tires and wheels are designed to give
your vehicle a sport appearance. With
low-profile tires, you may notice an
increase in road noise and faster tire
wear, depending on road conditions and
driving styles. Due to their design,
low-profile tires and wheels are more
prone to road damage from potholes,
rough or unpaved roads, car wash rails
and curb contact than standard tires and
wheels.
Note: Your vehicles warranty does not
cover these types of damage. Tires
should always be kept at the correct
inflation pressures and extra caution
should be taken when operating on
rough roads to avoid impacts that could
cause wheel and tire damage.

pneumatic passenger car tires. The
Quality grades can be found where
applicable on the tire sidewall between

Traction AA Temperature A.
These Tire Quality Grades are
determined by standards that the United

Tire Quality Grades apply to new

not apply to deep tread, winter-type

use spare tires, light truck or LT type
tires, tires with nominal rim diameters of
10 to 12 inches or limited production tires
as defined in Title 49 Code of Federal

U.S. Department of Transportation Tire
quality grades: The U.S. Department of
Transportation requires Ford Motor
Company to give you the following
information about tire grades exactly as
the government has written it.
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 1 ½ times as well on the
government course as a tire graded 100.
