Checking and replacing tires

Treadwear indicator

CHECKING YOUR TIRES

Check the tire's tread for treadwear
indicators. If the indicators show,
replace the tires. The location of
treadwear indicators is shown by
Δ
the "TWI" or " " marks, etc.,
molded on the sidewall of each
tire.
The tires on your Toyota have built−in
treadwear indicators to help you know
when the tires need replacement.
When the tread depth wears to 1.6
mm (0.06 in.) or less, the indicators
will appear. If you can see the indica-
tors in two or more adjacent grooves,
the tire should be replaced. The lower
the tread, the higher the risk of skid-
ding.
The effectiveness of snow tires is
lost if the tread wears down below
4 mm (0.16 in.).
If you have tire damage such as
cuts, splits, cracks deep enough to
expose the fabric, or bulges indi-
cating internal damage, the tire
should be replaced.
If a tire often goes flat or cannot be
properly repaired due to the size or
location of a cut or other damage, it
should be replaced. If you are not
sure, consult with your Toyota dealer.
2007 TUNDRA from Jul. '07 Prod. (OM34463U)
If air loss occurs while driving, do not
continue driving. Driving even a short
distance can damage a tire beyond
repair.
Any tires which are over 6 years
old must be checked by a qualified
technician even if damage is not
obvious.
Tires deteriorate with age even if they
have never or seldom been used.
This applies also to the temporary
spare tire and tires stored for future
use.
