CHECKING AND REPLACING TIRES
When to replace your tires
New treadTread wear indicator
Worn tread
Replace the tires when the tread wear indicators show.
The location of the tread wear indicators is shown by
the ªTWIº or ªº 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 tires 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.
