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.
â– 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 ification’s 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 and before long trips, use a gauge to measure the pressure in
all tires, including the spare. Even tires in good condition can lose 1 to 2 psi (10 to
20 kPa, 0.1 to 0.2 kgf/cm
2) per month.
â– 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 tread. 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 a deal er check the wheel alignment.
• Excessive tread wear.
2 Wear Indicators P. 306
•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.
Have a dealer check the tires if you feel a consistent
vibration while driving. Ne w tires and any that have
been removed and reinst alled should 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 instruction s in this owner’s
manual regarding ti re inflation and
maintenance.

Tire and Loading Information Label
The label attached to the driver’s doorjamb provides necessary tire and
loading information.
Tire Labeling
The tires that came on your vehicle have a
number of markings. Those you should be
aware of are described below.
Whenever tires are replaced, they should be replaced with tires of the same size.
1 Tire and Loading Information Label
The tire and loading informat ion label attached to the
driver’s doorjamb contains:
aThe number of people your vehicle can carry.
bThe total weight your vehicle can carry. Do not
exceed this weight.
cThe original tire sizes for front, rear, and spare.
dThe proper cold tire pressure for front, rear, and
spare.

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
Maximum Load Rating – Means the load rating for a tire at the maximum
permissible inflation pressure for that tire.
Recommended Inflation Pressure – The cold tire inflation pressure recommended
by the manufacturer.

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 inspections and inflation pressure maintenance, it is
recommended that you have annual inspections performed once the tires reach five
years old. All tires, including the spare, should be removed from service after 10
years from the date of manufacture, regard less of their condition or state of wear.

Replace your tires with radials of the same size, load range, speed rating, and
maximum cold tire pressure rating (as shown on the tire’s sidewall). Using tires of a

It is best to replace all four tires at the same time. If that isn’t possible, replace the
front or rear tires in pairs.
If you replace a wheel, only use TPMS spec ified wheels approved for your vehicle.
Make sure that the wheel’s specifications match those of the original wheels.

If a Tire Goes Flat
Changing a Flat Tire
If a tire goes flat while driving, grasp the steering wheel firmly, and brake
gradually to reduce speed. Then, stop in a safe place. Replace the flat tire with a
compact spare tire. Go to a dealer as soon as possible to have the full-size tire
repaired or replaced.
1.Park the vehicle on firm, level, non-slip pery surface and apply the parking brake.
2. Move the shift lever to

3. Set the parking brake.
4. Turn on the hazard warning lights and set the power mode to VEHICLE
1Changing a Flat Tire
Periodically check the tire pressure of the compact
spare. It should be set to the specified pressure.
Specified Pressure: 60 psi (420 kPa, 4.2 kgf/cm
2)
When driving with the compact spare tire, keep the
vehicle speed under 50 mph (80 km/h). Replace with
a full-size tire as soon as possible.
The compact spare tire and wheel in your vehicle are
specifically for this model.
Do not use them with another vehicle.
Do not use another type of compact spare tire or
wheel with your vehicle.
Do not mount tire chains on a compact spare tire.
If a chain-mounted front tire goes flat, remove one of
the full-size rear tires and replace it with the compact
spare tire. Remove the flat front tire and replace it
with the full-size tire that was removed from the rear.
Mount the tire chains on the front tire.
Do not use a puncture-repairi ng agent on a flat tire,
as it can damage the tire pressure sensor.

1. Store the jack in its holder. Turn the jack’s
end bracket to lock it in place.
2. Remove the center cap.
3. Place the flat tire face up in the spare
tire well.
4. Remove the spacer cone from the wing bolt
for the spare tire, and insert the wing bolt
for the normal tire back on the bolt. Secure
the flat tire with the wing bolt.
5. Securely store the wheel nut wrench and
jack handle bar back in the cargo area.
If you replace a flat tire with the spare tire, the low tire pressure/TPMS indicator
comes on while you are driving. After driving for a few miles (kilometers), the
indicator will start blinking for a short time and then stay on. CHECK TPMS

If you replace the tire with a specified regular tire, the warning message on the

a few miles (kilometers).

If the Low Tire Pressure/TPMS
Indicator Comes On or Blinks
â– Reasons for the indicator to come on or blink
A tire pressure is significantly low. If there is a problem with the TPMS or
the compact spare tire is installed, the indicator blinks for about one
minute, and then stays on.
â– What to do when the indicator comes on
Stop your vehicle in a safe place. Ch eck the tire pressure and adjust the
pressure to the specified level. The sp ecified tire pressure is on a label on
the driver side doorjamb.
â– What to do when the indicator blinks
Have the tire inspected by a dealer as soon as possible. If the compact
spare tire has triggered the indicator to blink, change the tire to a full-
size tire. The indicator goes off after a while.

NOTICE
Driving on an extremely underinflated tire can cause
it to overheat. An overheated tire can fail. Always
inflate your tires to the prescribed level.
