Tire Information (U.S.A.)
Tire MaintenanceImproper or inadequate vehicle maintenance can cause tires to w ear abnormally. Here are
some important maintenance points:
Tire Inflation PressureInspect all tire pressure monthly (including the spare) when the tires are cold. Maintain
recommended pressures for the best ride, top handling, and minimum tire wear. Use the
pressures specified on the vehicle tire information placard or t ire label for optimum service.
Tire RotationTo equalize tread wear, rotate the tires every 12,000 km (7,500 miles) at the latest or sooner
if irregular wear develops. Mazda recommends to rotate every 8,000 km (5,000 miles) to
help increase tire life and distribute wear more evenly.
Do not include (TEMPORAR Y USE ONLY)
spare tire in rotation. Forward
Inspect the tires for uneven wear and damage. Abnormal wear is usually caused by one or a
combination of the following: 
Incorrect tire pressure 
Improper wheel alignment 
Out-of-balance wheel 
Severe braking
After rotation, inflate all tire pressures to specification (page 9-8 ) and inspect the lug
nuts for tightness.
(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 page 4-108 .

Tire Information (U.S.A.)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. The period in which
the tire was manufactured (both week and year) is indicated by a 4-digit number.
Refer to Tire Labeling on page 8-24 .
Safety PracticesThe way you drive has a great deal to do with your tire mileage and safety. So cultivate good
driving habits for your own benefit. 
Observe posted speed limits and drive at speeds that are safe for the existing weather
conditions 
Avoid fast starts, stops and turns 
Avoid potholes and objects on the road 
Do not run over curbs or hit the tire against the curb when parking
CAUTION If you feel a sudden vibration or ride disturbance while driving or you suspect your tire
or vehicle has been damaged, immediately reduce your speed. Drive with caution until
you can safely pull off the road. Stop and inspect the tire for damage. If the tire is under-
inflated or damaged, deflate it, remove the tire and rim and replace it with your spare tire.
If you cannot detect a cause, have the vehicle towed to the nearest vehicle or tire dealer to
have the vehicle inspected.
