Mazda 3 Owners Manual: Replacing a Tire

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.

(With tire pressure monitoring system)

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 on .

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.
