Checking and changing tires  
WARNING  
Tread wear indicator  
Keeps tires properly inflated.  
Otherwise, the following situations and an accident  
resulting in death or serious injury may occur.  
Low tire pressure (underinflation) -  
• Excessive wear and tear  
• Uneven wear  
• Poor control  
• Possibility of deflation from an  
overheated tyre  
TIRE CHECK  
Check tires using tread wear indicators. If you see  
the indicators, replace the tire. Their location is  
indicated by the "TWI" or " " marks on the side of  
each tire.  
• Poor tire tightness  
• Wheel deformation and/or tire  
wear  
• Greater possibility of tire damage  
when hitting an obstacle on the road  
The tires on your vehicle have built-in tread wear  
indicators to help you determine when the tires should be  
replaced. When the tread profile is worn to 1.6 mm or less,  
indicators will appear.  
High tire pressure (overinflation) -  
• Poor control  
• Excessive wear and tear  
• Uneven wear  
Visible indicators in two or more adjacent profiles signal  
that the tire needs to be replaced. The lower the tread, the  
higher the risk of skidding.  
• Greater possibility of tire damage  
when hitting an obstacle on the road  
The effectiveness of winter tires is minimal if the tread  
depth is less than 4mm.  
If you have a damaged tire, such as a cut, tear, crack  
that shows fabric, or a bulge that indicates internal  
damage, the tire needs to be replaced.  
If the tire frequently leaks or cannot be properly repaired  
due to the size or location of the tear or other damage, it  
should be replaced. If you are not sure, consult any  
authorized Toyota dealer or service center, or another  
properly qualified and equipped professional.

If air leaks occur while driving, do not continue driving  
with a flat tire.  
Never use "second-hand" tires on your vehicle.  
Driving even a short distance can irreparably damage  
the tire.  
The history of used tires is not known and that is  
dangerous.  
Any tire older than 6 years must be checked by a  
technician, even if its damage is not visible.  
Toyota recommends changing all four tires at once,  
or both front or both rear tires at once.  
The condition of tires deteriorates with age, even  
if you do not use them at all or only a little.  
Procedure for changing tires - see "When a tire is  
damaged" on page 329 in Chapter 4.  
This also applies to the spare wheel and tires stored for  
later use.  
After changing a tire, the bike should always be  
balanced.  
CHANGING TIRES  
When replacing tires, use only tires of the same size,  
brand, construction, and load capacity as the original  
tires.  
An unbalanced wheel can impair vehicle handling and  
reduce tire life. With regular use, the wheels become  
unbalanced, so have them balanced occasionally.  
When replacing a tubeless tire, the valve  
should also be replaced with a new one.  
Using a different size or type could greatly affect vehicle  
handling, ride, speedometer/odometer calibration,  
ground clearance, and distance between body and tires  
or snow chains.  
WARNING  
Follow the instructions below. Otherwise, an  
accident resulting in death or serious injury may  
occur.  
• Do not use a combination of radial, diagonal or  
retreaded tires. This can cause a deterioration  
in vehicle handling resulting in loss of vehicle  
control. In Germany, the use of different types  
of tires is prohibited by decree.  
• Do not use tires of a different size  
than that recommended by the  
manufacturer, as this may cause  
dangerous vehicle handling  
characteristics leading to loss of vehicle control.

Changing tires  
WARNING  
Do not use a compact spare wheel when  
changing tires. This is for temporary use  
only.  
Vehicles with a compact spare wheel  
Vehicles without a compact spare wheel  
For even tire wear and to increase their  
service life, Toyota recommends that you  
rotate the tires approximately every 10,000  
km.  
However, the interval for changing tires is  
best determined according to the driving  
style and the condition of the road where the car is operated.  
Tire replacement procedure - see "When a  
tire is damaged" on page 329 in chapter 4.  
When changing tires, check for uneven wear  
and damage. Excessive wear is the result of  
incorrect tire pressure, misaligned wheel  
geometry, wheel imbalance or heavy braking.
