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 cannot be properly repaired due to the size or
location of a cut or other damage
If you are not sure, consult with any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.
■
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.
■
Low profile tires (vehicles with 165/60R15 tires)
Generally, low profile tires will wear more rapidly and tire grip performance
will be reduced on snowy and/or icy roads when compared to standard tires.
Be sure to use snow tires or tire chains on snowy and/or icy roads and drive
carefully at a speed appropriate for road and weather conditions.
■
If the tread on snow tires wears down below 4 mm (0.16 in.)
The effectiveness of the tires as snow tires is lost.
Tire pressure warning system (if equipped)
Tire pressure warning system (if equipped)
Tire pressure warning system (if equipped)
Your vehicle is equipped with a tire pressure warning system.
While the vehicle is in motion, the system monitors the fluctuations in
the wheel speed signals that are output by the speed sensor for the
brake control system.
It informs the driver if it detects a low tire inflation pressure.
◆
Initializing the tire pressure warning system
■
The tire pressure warning system must be initialized when
changing the tire
When the tire pressure warning system is initialized, the current tire
inflation pressure is set as the benchmark pressure.
■
The initialization operation
● Make sure to carry out initialization after adjusting the tire infla-
tion pressure. Also, make sure the tires are cold before carrying
out initialization or tire inflation pressure adjustment.
● If you accidentally press the reset switch when initialization is not
necessary, adjust the tire inflation pressure to the specified level
when the tires are cold, and conduct initialization again.
