Tire Maintenance
Improper or inadequate vehicle maintenance can cause tires to wear abnormally. Here are
some important maintenance points:
Tire Infl ation 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 specifi ed 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 distribute 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, infl ate all tire pressures to specifi cation (page 9-9 ) 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 4-153 .
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.

Replacing a Tire
WARNING
Always use tires that are in good condition:
Driving with worn tires is dangerous. Reduced braking, steering, and traction could result
in an accident.

If a tire wears evenly, a wear indicator will appear as a solid band across the tread.
Replace the tire when this happens.

New treadTread wear indicator

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 page 4-153 .
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.
Refer to Tire Labeling on page 8-24 .

 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-
infl ated or damaged, defl ate it, remove the tire and rim and replace it with your spare tire.

Vehicle Loading
This section will guide you in the proper loading of your vehicle and/or trailer, to keep your
loaded vehicle weight within its design rating capability, with or without a trailer. Properly
loading your vehicle will provide maximum return of vehicle design performance. Before
loading your vehicle, familiarize yourself with the following terms for determining your
vehicle's weight ratings, with or without a trailer, from the vehicle's Safety Certifi cation
Label and Tire and Load Information Label:
WARNING
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 failure, handling or steering
problems, irregular tire wear, tire failure or other damage.
Overloading makes a vehicle harder to drive and 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 infl ation pressure.
Never overload the vehicle and always observe the vehicle's weight ratings from the
vehicle's Safety Certifi cation and Tire and Load Information labels.

Base Curb Weight is the weight of the vehicle including a full tank of fuel and all
standard equipment. It does not include passengers, cargo, or optional equipment.

Vehicle Curb Weight is the weight of your new vehicle when you picked it up from your
dealer plus any aftermarket equipment.

Payload is the combination weight of cargo and passengers that the vehicle is designed
to carry. The maximum payload for your vehicle can be found on the Tire and Load
Information label on the driver's door frame or door pillar. Look for “THE COMBINATION
WEIGHT OF OCCUPANTS AND CARGO SHOULD NEVER EXCEED XXX kg or
XXX lbs” for your maximum payload. The payload listed on the tire label is the maximum
payload for the vehicle as built by the assembly plant. If any aftermarket or dealer installed
equipment has been installed on the vehicle, the weight of the equipment must be subtracted
from the payload listed on the tire label in order to be accurate.

Cargo Weight includes all weight added to the Base Curb Weight, including cargo and
optional equipment. When towing, trailer tongue load or king pin weight is also part of
cargo weight.

The cargo weight limit decreases depending on the number of vehicle occupants. The cargo
weight limit can be calculated by subtracting the total weight of the vehicle occupants from
the “combination weight of occupants and cargo should never exceed” value on the tire
label.

Examples: Based on a single occupant weight of 68 kg (150 lbs), and a value of 385 kg (849
lbs) for the “combination weight of occupants and cargo should never exceed”:
The cargo weight limit with one occupant is 385 kg (849 lbs) - 68 kg (150 lbs) = 317 kg
(699 lbs)
The cargo weight limit with two occupants is 385 kg (849 lbs) - (68 × 2) kg ( (150 × 2) lbs)
= 249 kg (549 lbs)
If the weight of the occupant increases, the cargo weight limit decreases by that much.

GAW (Gross Axle Weight) is the total weight placed on each axle (front and rear) -
including vehicle curb weight and all payload.

GAWR (Gross Axle Weight Rating) is the maximum allowable weight that can be carried
by a single axle (front or rear). These numbers are shown on the Safety Compliance
Certifi cation Label located on the driver's door frame or door pillar. The total load on
each axle must never exceed its GAWR.

GVW (Gross Vehicle Weight) is the Vehicle Curb Weight cargo passengers.

GVWR (Gross Vehicle Weight Rating) is the maximum allowable weight of the fully
loaded vehicle (including all options, equipment, passengers and cargo). The GVWR is
shown on the Safety Compliance Certifi cation Label located on the driver's door frame
or door pillar. The GVW must never exceed the GVWR.

WARNING
Never Exceed Axle Weight Rating Limits:
Exceeding the Safety Certifi cation Label axle weight rating limits is dangerous and could
result in death or serious injury as a result of substandard vehicle handling, performance,
engine, transmission and/or structural damage, serious damage to the vehicle, or loss of
control.
Always keep the vehicle within the axle weight rating limits.

GCW
GCW (Gross Combination Weight) is the weight of the loaded vehicle (GVW) plus the
weight of the fully loaded trailer.

GCWR (Gross Combination Weight Rating) is the maximum allowable weight of the
vehicle and the loaded trailer - including all cargo and passengers - that the vehicle can
handle without risking damage. (Important: The towing vehicle's braking system is rated
for operation at GVWR, not at GCWR. Separate functional brakes should be used for safe
control of towed vehicles and for trailers weighing more than 1,500 lbs). The GCW must
never exceed the GCWR.

Maximum Loaded Trailer Weight is the highest possible weight of a fully loaded trailer
the vehicle can tow. It assumes a vehicle with only mandatory options, no cargo (internal
or external), a tongue load of 10-15% (conventional trailer) or king pin weight of 15-25%
(fi fth-wheel trailer), and driver only (150 lbs). Consult your dealership (or the RV and
Trailer Towing Guide provided by your dealership) for more detailed information.
Tongue Load or Fifth-Wheel King Pin Weight refers to the amount of the weight that a
trailer pushes down on a trailer hitch.

Examples: For a 5000 lb conventional trailer, multiply 5000 by 0.10 and 0.15 to obtain a
proper tongue load range of 500 to 750 lbs. For an 11,500 lb fi fth-wheel trailer, multiply by
0.15 and 0.25 to obtain a proper king pin load range of 1,725 to 2,875 lbs.
