Maintenance and care
Check if the treadwear indica-
tors are showing on the tires.
Also check the tires for uneven
wear, such as excessive wear
on one side of the tread.
Check the spare tire condition
and pressure if not rotated.
New tread
Worn tread
Treadwear indicator
The location of treadwear indicators
is shown by a “TWI” or “ ” mark,
etc., molded into the sidewall of
each tire.
Replace the tires if the treadwear
indicators are showing on a tire.
■ When to replace your vehicle’s
tires
Tires should be replaced if:
● The treadwear indicators are
showing on a tire.
● You have tire damage such as
cuts, splits, cracks deep enough
to expose the fabric, and bulges
indicating internal damage
● A tire goes flat repeatedly or can-
not be properly repaired due to
the size or location of a cut or
other damage
If you are not sure, consult your
Toyota dealer.
■ Tire life
Any tire over 6 years old must be
checked by a qualified technician
even if it has seldom or never been
used or damage is not obvious.
■ Low profile tires (vehicles with
195/50R19 tires)
Generally, low profile tires will wear
more rapidly and tire grip perfor-
mance will be reduced on snowy
and/or icy roads when compared to
standard tires. Be sure to use snow
tires on snowy and/or icy roads and
drive carefully at a speed appropri-
ate for road and weather conditions.
■ Maximum load of tire
Check that the maximum load of the
replacement tire is greater than 1/2
of the Gross Axle Weight Ratings
(GAWR) of either the front axle or
the rear axle, whichever is greater.
For the GAWR, see the Certification
Label. For the maximum load of the
tire, see the load limit at maximum
cold tire inflation pressure men-
tioned on the sidewall of the tire.

Replace or rotate tires in
accordance with mainte-
nance schedules and tread-
wear.
