Maintenance and care
Rotate the tires in the order shown.
To equalize tire wear and help extend tire life, Toyota recommends that tire 
rotation is carried out approximately every 10000 km (6000 miles).
■ 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. 
■ If the tread on snow tires wears down below 4 mm (0.16 in.) 
The effectiveness of the tires as snow tires is lost.
