Action to be taken
Inspect the tires and adjust to the specified inflation pressur e (page 6-36).
CAUTION
When replacing/repairing the tires or wheels or both, have the work done by an Authorized Mazda Dealer, or the
tire pressure sens ors may be damaged.
NOTE
•Perform tire pressure adjustment when the tires are cold . Tire pressure will vary according to the tire tempera-
ture, therefore let the vehicle stand for 1 hour or only drive it 1.6 km (1 mile) or less before adjusting the tire
pressures. When pressure is adjusted on hot tires to the cold inflation pressure, the TPMS warning light/beep
may turn on after the tires cool and pressure drops below specification.
Also, an illuminated TPMS warning light, resulting from th e tire air pressure dropping due to cold ambient
temperature, may turn off if the ambien t temperature rises. In this case, it will also be necessary to adjust the
tire air pressures. If the TP MS warning light illuminates due to a drop in tire air pressure, make sure to check
and adjust the tire air pressures.
•After adjusting the tire air pressures, it may require some time for the TPMS warning light to turn off. If the
TPMS warning light remains illuminated, drive the vehicle at a speed of at least 25 km/h (16 mph) for 10 mi-
nutes, and then verify that it turns off.
•Tires lose air naturally over time and the TPMS cannot tell if the tires are getting too soft over time or you
have a flat. However, when you find one low tire in a se t of four-that is an indication of trouble; you should
have someone drive the vehicle slowly forward so you can inspect any low tire for cuts and any metal objects
sticking through tread or sidewall. Pu t a few drops of water in the valve stem to see if it bubbles indicating a
bad valve. Leaks need to be addressed by more than simply refilling th e trouble tire as leaks are dangerous ―
take it to an Authorized Mazda Dealer which has all th e equipment to fix tires, TPMS systems and order the
best replacement tire for your vehicle.
If the warning light illuminates again even after the tire pressures are adjusted, there may be a tire puncture.

Uniform Tire Quality Grading System (UTQGS)
This information relates to the tire grading system developed by the U.S. National Highway
Traffic Safety Administration for grading tires by tread wear, traction, and temperature
performance.
▼ Tr e a d We a r
The tread wear grade is a comparative rating based on the wear rate of the tire when tested
under controlled conditions on a specified government test cour
se.
For example, a tire graded 150 would wear one-and-a-half times as well on the government
course as a tire graded 100.

The relative performance of tires depends upon the actual condi tions of their use, however,
and may depart significantly from the norm because of variation s in driving habits, service
practices and differences in ro ad characteristics and climate.
▼Traction-AA, A, B, C
The traction grades, from highest
to lowest, are AA, A, B, and C. These grades represent the
tire's ability to stop on wet pavement as measured under contro lled conditions on specified
government test surfaces of asphalt and concrete. A tire marked C may have poor traction
performance.
WA R N I N G
The traction grade assigned to this tire is based on braking (straight ahead) traction tests and
does not include acceleration cornering (turning), hydroplaning, or peak traction
characteristics.
▼ Temperature-A, B, C
The temperature grades A (the hi
ghest), B, and C, represent the tire's resistance to the
generation of heat and its ability to dissipate heat when teste d under controlled conditions
on a specified indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to degenerate and reduce tire
life, and excessive temperatures can lead to sudden tire failure.

Grade C corresponds to a level of performance which all passeng er vehicle tires must meet
under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher
levels of performance on the labo ratory test wheel than the minimum required by law.

Tire Maintenance
Improper or inadequate vehicle maintenance can cause tires to w ear abnormally. Here are
some important maintenance points:
▼ Tire Inflation Pressure
Inspect all tire pressu
re monthly (including the spare) when th e tires are cold. Maintain
recommended pressures for the best ride, top handling, and mini mum tire wear. Use the
pressures specified on the vehicle tire information placard or tire label for optimum service.
▼Tire Rotation
To 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 d istribute wear more evenly.
Do not include (TEMPORARY 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 (pa ge 9-7) and inspect the lug nuts
for tightness.
CAUTION
Rotate unidirectional tires and radial tires that have an asymmetrical tread pattern or studs
only from front to rear, not from side to side . Tire performance will be weakened if rotated
from side to side.
