Worn tread
The location of treadwear indicators is
shown by the “TWI” or “” marks, etc.,
molded on the sidewall of each tire.
Check spare tire condition and pres-
sure if not rotated.
Rotate the tires in the order shown.
To equalize tire wear and extend tire life, Lexus recommends that tire rotation is
carried out at the same interval as tire inspection.
Do not fail to initialize the tire pressu re warning system after tire rotation.
