TOWING A TRAILER
Do not tow a trailer with your vehicle.
FLAT TOWING
UNIFORM TIRE QUALITY GRADING
Towing your vehicle with all four wheels on the
ground is sometimes called flat towing. This
method is typically used when towing a vehicle
behind a recreational vehicle, such as a motor
home.
DOT (Department Of Transportation) Quality
Grades: All passenger car tires must conform to
federal safety requirements in addition to these
grades.
Quality grades can be found where applicable on
the tire sidewall between tread shoulder and
maximum section width. For example:
CAUTION

Failure to follow these guidelines can
result in severe reduction gear dam-
age.

DO NOT tow this vehicle with all four
wheels on the ground (flat towing).
For emergency towing procedures re-
fer to “Towing your vehicle” in the “In
case of emergency” section of this
manual.
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment 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 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 AA, A, B AND C
The traction grades, from highest to lowest, are
AA, A, B and C. Those grades represent the tire’s
ability to stop on wet pavement as measured
