Worn tread
Replace the tires when the tread wear indicators show. The
location of the tread wear indicators is shown by the ”TWI” or
”
Δ” marks molded on the sidewall of each tire.
The tires on your Lexus have built−in tread wear 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 replaced.
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 indicating 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 Lexus dealer.
If an air loss occurs while driving, do not continue driving with a
deflated tire. 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 also applies to the spare tire and tires stored for future use.
