WARNING
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.
If a tire wears evenly, a wear indicator will appear as a solid band across the tread. Replace the tire when this happens.
You should replace the tire before the band crosses the entire tread.
After adjusting the tire pressure, initialization of the tire pressure monitoring system is necessary to make the system operate normally.
Refer to Tire Pressure Monitoring System Initialization
NOTE
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. You should replace the spare tire when you replace the other road tires due to the aging of the spare tire. The period in which the tire was manufactured (both week and year) is indicated by a 4-digit number.
Refer to Tire Labeling.
