Checking And Replacing Tires - Toyota LAND CRUISER Owner's Manual

Checking and replacing tires

Tread wear indicator
CHECKING YOUR TIRES
Check the tire's tread for treadwear in-
dicators. If the indicators show, replace
the tires. The location of treadwear in-
dicators is shown by the "TWI" or "D"
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 indicators in two or more
adjacent grooves, the tire should be re-
placed. The lower the tread, the higher
the risk of skidding.
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 splits, cracks deep enough to expose splits, cracks deep enough to expose

REPLACING YOUR TIRES
When replacing a tire, use a tire of the
same size and construction, and the
same or greater load capacity as the
originally installed tires. Also, all the
tires must be the same brand and have
the same tread patterns.
Using any other size or type of tire may
seriously affect handling, ride, speedome-
ter/odometer calibration, ground clearance,
and clearance between the body and tires
or snow chains.
CAUTION
Observe the following instructions.
Otherwise, an accident may occur re-
sulting in death or serious injuries.
D Do not mix radial, bias belted, or
bias−ply tires on your vehicle, as
this may cause dangerous handling
characteristics resulting in loss of
control.
Do not use tires other than the
D
manufacturer's recommended size,
as this may cause dangerous han-
dling characteristics resulting in
loss of control.
