CHECKING YOUR TYRES

Check the tyre thread for the tread wear indicators. If the indicators show, replace the tyres.
The tyres of your Toyota have built-in tread wear indicators to help you know when the tyres need replacement. When the tread depth wears to 1.6mm (0.06 in.) or less, the indicators will appear. If you can see the indicators in two or more adjacent grooves, the tyres should be replaced. the lower the tread, the higher the risk fo skidding.

The effectiveness of snow tyres is lost if the tread wears down below 4mm (0.16 in.).

Check the tyres regularly for damage such as cuts, splits and cracks. If any damage is found, consult with a technician and have the tyre repaired or replaced.
Even if the damage does not appear serious, a qualified technician should examine the damage. Objects which have penetrated the tyre may have caused internal damage.

Any tyres which are over six years old must be checked by a qualified technician even if damage is not obvious.
Tyres deteriorate with age even if they have never or seldom been used.
this also applied to the spare tyres and tyres stored for future use.

REPLACING YOUR TYRES

When replacing a tyre, use only the same size and construction as originally installed and with the same or greater load capacity.
Using any other size or typre of tyre may seriously affect handling, ride, speedometer/odometer calibration, ground clearance, and clearance between the body and tyre or snow chains.
Contact your Toyota dealer for 205/55R16 spare tyres.

CAUTION:

Do not mix radial, bias belted or bias-ply tyres on your vehicle. It can cause dangerous handling characteristics, resulting in loss of control. In Germany, use of different tyre construction combinations is forbidden by SrVZO.

Never use second-hand tyres on your Toyota.
Using tyres whois previous history is unknown is a risk.

Toyota recommends all four tyres, or at least both of the front or rear tyres be replaces at a time as a set.
See If you have a flat tyre for tyre change procedure.

When a tyre is replaced, the wheel should always be balanced.
An unbalanced wheel may affect vehicle handling and tyre life. Wheels can get out of balance with regular use and should therefore be balanced occasionally.

When replacing a tubeless tyre, the air valve should also be replaced with a new one.
