flat tire MAZDA MODEL CX-3 2021 Service Manual

Location of the Tire Label (Placard)
You will find the tire label containing tire inflation pressure by tire size and other important
information on the driver's side B-pillar or on the edge of the driver's door frame.

SAMPLE
▼ Recommended Tire Inflation Pressure
On the tire label you will find the recommended
tire inflation pressure in both kPa and psi
for the tires installed as origin al equipment on the vehicle. It is very important that the
inflation pressure of the tires on your vehicl e is maintained at the recommended pressure.
You should check the tire pressu re regularly to insure that the proper inflation pressure is
maintained.
Refer to Tires on page 9-7.
NOTE
Tire pressures listed on the vehicle placar d or tire information label indicate the
recommended cold tire inflation pressure, measured when the tires are cold, after the vehicle
has been parked for at least 3 hours. As you drive, the temperature in the tire warms up,
increasing the tire pressure.

WARNING
Always check the tire inflation pressures on a regular basis according to the recommended
tire inflation pressure on the tire label and in conjunction with the information in this owner's
manual:
Driving your vehicle with under-inflated tires is dangerous.
Under-inflation is the most common cause of failures in any kind of tire and may result in
severe cracking, tread separation or “blowout”, with unexpected loss of vehicle control and
increased risk of injury. Under-inflation inc reases sidewall flexing and rolling resistance,
resulting in heat buildup and internal damage to the tire. It results in unnecessary tire stress,
irregular wear, loss of control and accidents. A ti re can lose up to half of its air pressure and
not appear to be flat!
It is impossible to determine whether or not tires are properly inflated just by looking at them.
▼Checking Tire Pressure
1. When you check the air pressure, make sure the tires are cold
―meaning they are not
hot from driving even a mile.
2. Remove the cap from the valve on one tire.
3. Firmly press a tire gauge onto the valve.
4. Add air to achieve recommended air pressure.
5. If you overfill the tire, release air by push ing on the metal stem in the center of the
valve. Then recheck the pressure with your tire gauge.
6. Replace the valve cap.
7. Repeat with each tire, including the spare.
NOTE
Some spare tires require higher inflation pressure.
8. Visually inspect the tires to make sure there are no nails or other objects embedded that
could poke a hole in the tire and cause an air leak.
9. Check the sidewalls to make sure there are no gouges, cuts, bulges, cracks or other irregularities.
▼Glossary of Terms
Tire Placard:
A label indicating the OE tire sizes, recommended inflation pressure, and the
maximum weight the vehicle can carry.
Tire Identificatio n Number (TIN): A number on the sidewall of each tire providing
information about the tire brand and manufacturi ng plant, tire size, and date of manufacture.
Inflation Pressure: A measure of the amount of air in a tire.
kPa: Kilopascal, the metric unit for air pressure.
psi: Pounds per square inch, the English unit for air pressure.
B-pillar: The structural member at the side of the vehicle behind the front door.

Tire Maintenance
Improper or inadequate vehicle maintenance can cause tires to wear abnormally. Here are
some important maintenance points:
▼Tire Inflation Pressure
Inspect 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 informat
ion 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 di
stribute 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 sp ecification (page 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.

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 ne arest vehicle or tire dealer to have the vehicle
inspected.

Do not tow a trailer with this vehicle:
Towing a trailer with this vehicle is dangerous because it has not been designed to tow a
trailer and doing so will affect the drive system which could result in vehicle damage.
This section will guide you in the proper loading of your vehicle, to keep your loaded
vehicle weight within its design rating capability. Properly loading your vehicle will provide
maximum return of vehicle design performance. Before loading your vehicle, familiarize
yourself with the following terms for determin ing your vehicle's weight ratings, from the
vehicle's Safety Certification Label and Tire and Load Information Label:
WA R N I N G
Overloaded Vehicle:
Overloading a vehicle is dangerous. The results of overloading can have serious consequences
in terms of passenger safety. Too much weight on a vehicle's suspension system can cause
spring or shock absorber failure, brake failu re, handling or steering problems, irregular tire
wear, tire failure or other damage.
Overloading makes a vehicle harder to drive an d control. It also increases the distance
required for stopping. In cases of serious overloading, brakes can fail completely, particularly
on steep grades. The load a tire will carry safely is a combination of the size of the tire, its load
range, and corresponding inflation pressure.
Never overload the vehicle and always observe th e vehicle's weight ratings from the vehicle's
Safety Certification and Tire and Load Information labels.
