Tire Information

Tire Size Designation

A tire's sidewall is marked with a tire size designation. You will need this
information when selecting replace-
ment tires for your car. The follow-
ing explains what the letters and
numbers in the tire size designation

mean.

(Example tire size designation)
P205/65R15 92S
P —
Applicable vehicle type (tires
marked with the prefix "P" are
intended for use on passenger cars;
however, not all tires have this
marking).

205 —
Tire width in millimeters.
65 —
Aspect ratio. The tire's section
height as a percentage of its width.
R —
Tire construction code (Radial).
15 —
Rim diameter in inches. 92
—
Load Index, a numerical code

associated with the maximum load

the tire can carry.

S —
Speed Rating Symbol. See the

speed rating chart in this section for

additional information.

Wheel Size Designation

Wheels are also marked with important information that you needif you ever have to replace one. The
following explains what the letters and numbers in the wheel size
designation mean.
(Example wheel size designation)

15
x
6
JJ
15 —
Rim diameter in inches.
6 —
Rim width in inches.
JJ —
Rim contour designation.
Tire Speed Ratings

The chart below shows many of the
different speed ratings currently

being used for passenger car tires.

The speed rating symbol is part of the tire size designation on the
sidewall of the tire. This symbol

corresponds to that tire's designed

maximum safe operating speed.

Tire Information

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
171).

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 perform- ance 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 ofthe tire when tested under controlledconditions 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.

Tire Information

Traction
The traction grades, from highest to lowest, are A, B, and C, and they
represent the tire's ability to stop on
wet pavement as measured under controlled conditions on specified
government test surfaces of asphalt and concrete. A tire marked C may
have poor traction performance.
Warning: The traction grade as- signed to this tire is based on brak-
ing (straight ahead) traction tests
and does not include cornering (turning) traction.
Temperature

The temperature grades are A (the highest), B, and C, representing the
tire's resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled conditions on a specified indoor
laboratory test wheel. Sustained high
temperature can cause the material of the tire to degenerate and reduce
tire life, and excessive temperature can lead to sudden tire failure. The
grade C corresponds to a level of
performance which all passenger car
tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent
higher levels of performance on the
laboratory test wheel than the
minimum required by law.
Warning: The temperature grade for

this tire is established for a tire that
is properly inflated and not over-

loaded. Excessive speed, underinfla-
tion, or excessive loading either
separately or in combination, can

cause heat build-up and possible tire

failure.

Emission Controls

The burning of gasoline in your car's engine produces several byproducts.
Some of these are carbon monoxide (CO), oxides of nitrogen (NOx) and
hydrocarbons (HC). Gasoline evaporating from the tank also
produces hydrocarbons. Controlling
the production of NOx, CO, and HC is important to the environment.
Under certain conditions of sunlight
and climate, NOx and HC react to
form photochemical "smog." Carbon
monoxide does not contribute to smog creation, but it is a poisonous

gas.
The Clean Air Act
The United States Clean Air Act* sets standards for automobile
emissions. It also requires that
automobile manufacturers explain to owners how their emission controls
work and what to do to maintain them. This section summarizes how
the emission controls work.
Scheduled maintenance is on page 142.
* In Canada, Honda vehicles comply
with the Canadian Motor Vehicle Safety Standards (CMVSS) for
Emissions valid at the time they are
manufactured. Crankcase Emission Control
System
Your car has a Positive Crankcase
Ventilation System. This keeps gasses that build up in the engine's crankcase from going into the
atmosphere. The Positive Crankcase
Ventilation valve routes them from the crankcase back to the intakemanifold. They are then drawn into
the engine and burned.
Evaporative Emission Control
System
As gasoline evaporates in the fuel tank, an evaporative emission controlcanister filled with charcoal adsorbs
the vapor. It is stored in this canister
while the engine is off. After the engine is started and warmed up, the
vapor is drawn into the engine and burned during driving.

Emission Controls

Exhaust Emission Controls

The exhaust emission controls include four systems: PGM-FI,
Ignition Timing Control, ExhaustGas Recirculation and Three Way
Catalytic Converter. These four
systems work together to control the
engine's combustion and minimize
the amount of HC, CO, and NOx that
comes out the tailpipe. The exhaust
emission control systems are
separate from the crankcase and
evaporative emission control

systems.

PGM-FI System

The PGM-FI System uses sequential multiport fuel injection.It has three subsystems: Air Intake,
Engine Control, and Fuel Control.
The Powertrain Control Module (PCM) uses various sensors to
determine how much air is going
into the engine. It then controls how
much fuel to inject under all operat-
ing conditions. Ignition Timing Control System
This system constantly adjusts the ignition timing, reducing the amountof HC, CO and NOx produced.
Exhaust Gas Recirculation (EGR)
System

The Exhaust Gas Recirculation (EGR) system takes some of the
exhaust gas and routes it back into
the intake manifold. Adding exhaust
gas to the air/fuel mixture reduces
the amount of NOx produced when
the fuel is burned.
Three Way Catalytic Converter
The three way catalytic converter is in the exhaust system. Through
chemical reactions, it converts HC,CO, and NOx in the engine's exhaust
to carbon dioxide (CO 2), dinitrogen
(N 2), and water vapor. Replacement Parts

The emission control systems are designed and certified to work to-
gether in reducing emissions to
levels that comply with the Clean Air
Act. To make sure the emissions remain low, you should use only newGenuine Honda replacement parts or
their equivalent for repairs. Using
lower quality parts may increase the emissions from your car.
The emissions control systems are covered by warranties separate from
the rest of your car. Read your
warranty manual for more informa-
tion.

Three Way Catalytic Converter

The three way catalytic converter contains precious metals that serve
as catalysts, promoting chemical
reactions to convert the exhaust
gasses without affecting the metals.
The catalytic converter is referred to as a three-way catalyst, since it acts
on HC, CO, and NOx. A replacement
unit must be an original Honda part or its equivalent.
The three way catalytic converter must operate at a high temperature
for the chemical reactions to take
place. It can set on fire any com- bustible materials that come near it.
Park your car away from high grass,
dry leaves, or other flammables. A defective three way catalytic
converter contributes to air pollution,and can impair your engine's per-
formance. Follow these guidelines to
protect your car's three way catalytic converter.
Always use unleaded gasoline.Even a small amount of leaded
gasoline can contaminate the catalyst metals, making the three
way catalytic converter ineffective. Keep the engine tuned-up.
Have your car diagnosed and
repaired if it is misfiring, back-
firing, stalling, or otherwise not running properly.
