If you check air pressures when the
tires are hot [driven for several miles
(kilometers)], you will see readings 4
to 6 psi (30 to 40 kPa, 0.3 to 0.4
kgf/cm ) higher than the cold
readings. This is normal. Do not let
air out to match the recommended
cold air pressure. The tire will be
underinflated.
Use the pressure gauge that came
with your vehicle every time you
check the tires. This will make it
easier for you to tell if a pressure
loss is due to a tire problem and not
due to a variation between gauges.
While tubeless tires have some
ability to self-seal if they are
punctured, you should look closely
for punctures if a tire starts losing
pressure.
Recommended Tire Pressures
The following chart shows the
recommended cold tire pressures for
most normal and high-speed driving
conditions.
Front:
Tire Size Cold Tire Pressure
215/40R17 83Y 33 psi (230 kPa , 2.3
kgf/cm )
Rear:
Tire Size Cold Tire Pressure
255/40R17 94Y 40 psi (275 kPa , 2.8
kgf/cm )
The compact spare tire pressure is:
Front:
26 psi (180 kPa , 1.8 kgf/cm )
Rear:
32 psi (220 kPa , 2.2 kgf/cm )
For convenience, the recommended
cold air pressures and tire sizes are
on a label on the driver's doorjamb.
For additional information about
your tires, see page 204 .
Tire Inspection
Every time you check inflation, you
should also examine the tires for
damage, foreign objects, and wear.
You should look for:
Bumps or bulges in the tread or
side of the tire. Replace the tire if
you find either of these conditions.
Cuts, splits, or cracks in the side
of the tire. Replace the tire if you
can see fabric or cord.
Excessive tread wear.
