Tires
Replace or rotate tires in accordance with maintenance schedules and treadwear.
- Checking tires

1. New tread
2. Treadwear indicator
3. Worn tread
The location of treadwear indi- cators is shown by the “TWI” or “Δ” marks, etc., molded on the sidewall of each tire.
Check spare tire condition and pressure if not rotated.
- Tire rotation
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.

- The tire pressure warning system
Your Lexus is equipped with a tire pressure warning system that uses tire pressure warning valves and transmitters to detect low tire infla- tion pressure before serious problems arise.
