Checking and Maintaining Tires
Checking Tires
To safely operate your vehicle, your tires must be of the proper type and size, in 
good condition with adequate  tread, and properly inflated.
■Inflation guidelines
Properly inflated tires provid e the best combination of hand ling, tread life, and comfort. 
Refer to the driver’s doorjamb label or spec ifications page for the specified pressure.
Underinflated tires wear unev enly, adversely affect handling and fuel economy, and 
are more likely to fail from overheating.
Overinflated tires make your vehicle ride ha rshly, are more prone to road hazards, 
and wear unevenly.
Every day before you drive, look at each of  the tires. If one looks lower than the 
others, check the pressure with a tire gauge.
At least once a month or before long trips , use a gauge to measure the pressure in 
all tires. Even tires in good condition can lose 1–2 psi (10–20 kPa, 0.1–0.2 kgf/cm
2) 
per month.
■Inspection guidelines
Every time you check inflation, also  examine the tires and valve stems.
Look for:
• Bumps or bulges on the side or in the tr ead. Replace the tire if you find any cuts, 
splits, or cracks in the side of the tire . Replace it if you see fabric or cord.
• Remove any foreign objects  and inspect for air leaks.
• Uneven tread wear. Have an authorized H onda Clarity Plug-In Hybrid dealer check 
the wheel alignment.
• Excessive tread wear.
2 Wear Indicators  P. 506
•Cracks or other damage around valve stem.
1Checking Tires
Measure the air pressure when tires are cold. This 
means the vehicle has been parked for at least three 
hours, or driven less than 1 mile (1.6 km). If 
necessary, add or releas e air until the specified 
pressure is reached.
If checked when hot, tire pressure can be as much as 
4–6 psi (30–40 kPa, 0.3–0.4 kgf/cm
2) higher than if 
checked when cold.
Whenever tire pressure is adjusted, you must 
calibrate the TPMS. 2 TPMS Calibration P. 428
Have an authorized Honda Clarity Plug- In Hybrid 
dealer check the tires if you  feel a consistent vibration 
while driving. New tires and any that have been 
removed and reinstalled sh ould be properly balanced.
3WARNING
Using tires that are excessively worn or 
improperly inflated can cause a crash in 
which you can be seriously hurt or killed.
Follow all instructions in this owner’s 
manual regarding tire inflation and 
maintenance.

information.
Tire Labeling
The tires that came on your vehicle have a 
number of markings. Those you should be 
aware of are described as shown.
Whenever tires are replaced, they should be replaced with tires of the same size.

The tire identification number  (TIN) is a group of numbers and letters that look like 
the example in the side column. TIN is  located on the sidewall of the tire.
Cold Tire Pressure  – The tire air pressure when the vehicle has been parked for at 
least three hours or driven less than 1 mile (1.6 km).
Load Rating  – Means the maximum load that a ti re is rated to carry for a given 
inflation pressure.
Maximum Inflation Pressure  – The maximum tire air pressure that the tire can 
hold.
Maximum Load Rating  – Means the load rating for a tire at the maximum 
permissible inflation pr essure for that tire.
Recommended Inflation Pressure  – The cold tire inflation pressure recommended 
by the manufacturer.
Treadwear Indicators (TWI)  – Means the projections within the principal grooves 
designed to give a visual indication  of the degrees of wear of the tread.

DOT Tire Quality Grading (U.S. Vehicles)
The tires on your vehicle meet all U.S. Federal Safety 
Requirements. All tires are also  graded for treadwear, traction, 
and temperature performance a ccording to Department of 
Transportation (DOT) standards. The following explains these 
gradings.
Quality grades can be found where  applicable on the tire sidewall 
between tread shoulder an d maximum section width.
The treadwear grade is a comparative rating based on the wear 
rate of the tire when tested un der 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  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.

uuChecking and Maintaining Tires uDOT Tire Quality Grading (U.S. Vehicles)
Maintenance
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 under controlled conditions on specified 
government test surfaces of asph alt and concrete. A tire marked 
C may have poor traction performance.
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 te sted 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 ex cessive 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.
■Traction
■Temperature
1 Traction
Warning: The traction grade 
assigned to this tire is based on 
straight-ahead braking traction tests, 
and does not include acceleration, 
cornering, hydroplaning, or peak 
traction characteristics.
1Temperature
Warning: The temperature grade for 
this tire is establishe d for a tire that is 
properly inflated and not 
overloaded. Excessive speed, 
underinflation, or excessive loading, 
either separately or in combination, 
can cause heat buildup and possible 
tire failure.

uuChecking and Maintaining Tires uWear Indicators
Maintenance
Wear Indicators
The groove where the wear indicator is 
located is 1/16 inch (1.6 mm) shallower than 
elsewhere on the tire. If the tread has worn so 
that the indicator is ex posed, replace the tire. 
Worn out tires have poor traction on wet 
roads.
Tire Service Life
The life of your tires is dependent on many factors, including driving habits, road 
conditions, vehicle loading, inflation pre ssure, maintenance history, speed, and 
environmental conditions (even when the tires are not in use).
In addition to regular in spections and inflation pres sure maintenance, it is 
recommended that you have annual inspecti ons performed once the tires reach five 
years old. All tires should be removed fro m service after 10 years from the date of 
manufacture, regardless of their condition or state of wear.
