Tubeless tires have some ability
to self-seal if they are punctured.
However, because leakage is often
very slow, you should look closely
for punctures if a tire starts losing
pressure.
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.
TREAD WEAR
INDICATORS
Your car's tires have wear
indicators molded into the tread.
When the tread wears down to
that point, you will see a 1/2 inch
(12.7 mm) wide band running
across the tread. This shows
there is less than 1/16 inch
(1.6 mm) of tread left on the tire.
A tire that is this worn gives very
little traction on wet roads. You
should replace the tire if you can
see the tread wear indicator in
three or more places around the
tire.

LOCATION
In addition to proper inflation,
MARKS
correct wheel alignment helps to
decrease tire wear. You should get
your car's wheel alignment
checked every 12 months or
15,000 miles (24,000 km).
The tires were properly balanced
by the factory. They may need to
be rebalanced at some time
before they are worn out. Have
your dealer check the tires if you
feel a consistent vibration while
driving. A tire should always be
rebalanced if it is removed from
the wheel for repair.
