Tire Pressure Adjustment For
High Speed Driving
Honda strongly recommends that
you not drive faster than posted
speed limits and conditions allow. If
you decide it is safe to drive at high
speeds, be sure to adjust the cold tire
pressures as shown below. If you do
not adjust the tire pressure, exces-
sive heat can build up and cause
sudden tire failure.
Be sure to readjust the pressure for
normal driving speeds. You should
wait until the tires are cold before
adjusting the tire pressure (see page
198).
DOT Tire Quality Grading
(U.S. Cars)
The tires on your vehicle meet all
U.S. Federal Safety Requirements.
All tires are also graded for
treadwear, traction, and temperature
performance according to
Department of Transportation
(DOT) standards. The following
explains these gradings.
Tire Information
Treadwear
The treadwear grade is a compara-
tive 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 condi-
tions 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.
