▼Mounting the Tire
1. Remove dirt and grime from the
mounting surfaces of the wheel and
hub, including the hub bolts, with a
cloth.

WA R N I N G
Make sure the mounting surfaces of the
wheel, hub and lug nuts are clean
before changing or replacing tires:
When changing or replacing a tire, not
removing dirt and grime from the
mounting surfaces of the wheel, hub
and hub bolts is dangerous. The lug
nuts could loosen while driving and
cause the tire to come off, resulting in
an accident.
2. Mount the tire.
3. Install the lug nuts with the beveled edge inward; tighten them by hand.

WA R N I N G
Do not apply oil or grease to lug nuts
and bolts and do not tighten the lug
nuts beyond the recommended
tightening torque:
Applying oil or grease to lug nuts and
bolts is dangerous. The lug nuts could
loosen while driving and cause the tire

WARNING
Always securely and correctly tighten
the lug nuts:
Improperly or loosely tightened lug
nuts are dangerous. The wheel could
wobble or come off. This could result in
loss of vehicle control and cause a
serious accident.
Be sure to reinstall the same nuts you
removed or replace them with metric
nuts of the same configuration:
Because the wheel studs and lug nuts
on your Mazda have metric threads,
using a non-metric nut is dangerous.
On a metric stud, it would not secure
the wheel and would damage the stud,
which could cause the wheel to slip off
and cause an accident.
6. Remove the tire blocks and store the tools and jack.
7. Check the inflation pressure. Refer to Tires on page 9-8.
WA R N I N G
Do not drive with any tires that have
incorrect air pressure:
Driving on tires with incorrect air pressure
is dangerous. Tires with incorrect pressure
could affect handling and result in an
accident. When you check the regular tires'
air pressure, check the spare tire, too.
NOTE
To prevent the jack and tool from rattling,
store them properly.

Action to be taken
Inspect the tires and adjust to the specified inflation pressur e (page 6-38).
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 temper‐
ature, 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 the tire air pressure dropping due to cold ambient
temperature, may turn off if the ambient temperature rises. In this case, it will also be necessary to adjust the
tire air pressures. If the TPMS warnin g 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 illuminate d, drive the vehicle at a speed of at least 25 km/h (16 mph) for 10
minutes, 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 set 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. Put a few drops of water in the valve stem to see if it bubbles indicating a
bad valve. Leaks need to be addr essed by more than simply refilling the trouble tire as leaks are dangerous
― take it to an Authorized Mazda Dealer which has all the 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.
