Owners Manual_USA_M0C031_en
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 s
howing 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 with 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.
■Maximum load of tire
Check that the n umber given by 
dividing the maximum load by 1.10 
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 mentioned on 
the sidewall of the tire. ( P.551)
Tires
Replace or rotate tires in 
accordance with mainte-
nance schedules and tread-
wear.
