Replacing a Tire or a Wheel
Always use tires that are in good condition.
Driving with worn tires is dangerous. Reduced braking, steering, and traction could result in an accident.
Replace all four tires at the same time.
Replacing just one tire is dangerous. It could cause poor handling and poor braking resulting in loss of vehicle control. Mazda strongly recommends that you replace all four tires at the same time.
Always use wheels of the correct size on your vehicle.
Using a wrong-sized wheel is dangerous. Braking and handling could be affected, leading to loss of control and an accident.
A wrong-sized wheel may adversely affect:
-
Tire fit
-
Wheel and bearing life
-
Ground clearance
-
Snow-chain clearance
-
Speedometer calibration
-
Headlight aim
-
Bumper height
-
Tire Pressure Monitoring System
If a tire wears evenly, a wear indicator will appear as a solid band across the tread.
Replace the tire when this happens.
-
New tread
-
Worn tread
-
Tread wear indicator
You should replace the tire before the band crosses the entire tread.
Tires degrade over time, even when they are not being used on the road. It is recommended that tires generally be replaced when they are 6 years or older. Heat caused by hot climates or frequent high loading conditions can accelerate the aging process. The period in which the tire was manufactured (both week and year) is indicated by a 4-digit number.
Refer to Tire Labeling (Search).
