Replacing Tires
The tires that came with your
Honda were selected to match the
performance capabilities of the car
and provide the best combination
of handling, ride comfort, and long
life. You should replace them with
radial tires of the same size, load
range, and speed rating. Mixing ra-
dial and bias-ply or bias-belted
tires on your car can reduce its
braking ability, traction, and steer-
ing accuracy.
It is best to replace all four tires at
the same time. If that is not
possible or necessary, then
replace the two front tires or the
two rear tires as a pair. Replacing
just one tire can seriously affect
your car's handling.
If you ever need to replace a
wheel, make sure you use the
same style of wheel that originally
came on your Honda. Replacement
wheels are available at your
Honda dealer.

DOT Tire Quality Grading
(U.S. Cars)
The tires on your car 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.
Treadwear
The treadwear grade is a compara-
tive rating based on the wear rate of
the tire when tested under con-
trolled conditions on a specified
government test course. For ex-
ample, 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 per-
formance of tires depends upon
the actual conditions of their use,
however, and may depart signifi-
cantly from the norm due to varia-
tions in driving habits, service
practices and differences in road
characteristics and climate.
