Tire Rotation
To equalize tread wear, rotate the tires
every 16,000 km (10,000 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.

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 on page 10-71 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.
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.
1. New tread
2. Worn tread
3. Tread wear indicator

You should replace the tire before the
band crosses the entire tread.
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 load ing 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 10-30.

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 Certification 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 sa fety. Too much weight on a vehicle's
suspension system can cause spring or shoc k 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 inflation
pressure.
Never overload the vehicle and always observe the vehicle's weight ratings from the
vehicle's Safety Certification and Tire and Load Information labels.
Base Curb Weight is the weight of the ve hicle including a full tank of fuel and all
standard equipment. It does not include passengers, cargo, or optional
equipment.

Ve h i c l e C u r b We i g h t is the weight of your new vehicle when you picked it up from
your dealer plus any aftermarket equipment.

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 weig ht 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 Certification Label located on the driver's door frame or door pillar.
The total load on each axle must never exceed its GAWR.

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 Certification Label located on the driver's
door frame or door pillar. The GVW must never exceed the GVWR.

SAMPLE
WARNING
Never Exceed Axle Weight Rating Limits.
Exceeding the Safety Certification 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 (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 - incl uding 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% (fifth-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 fifth-wheel
trailer, multiply by 0.15 and 0.25 to obt ain a proper king pin load range of 1,725 to
2,875 lbs.
WARNING
Never Exceed GVWR or GAWR Specifications.
Exceeding the GVWR or the GAWR specified on the certification label is dangerous.
Exceeding any vehicle rating limitation could result in a serious accident, injury, or
damage to the vehicle.
Do not use replacement tires with lower lo ad carrying capacities than the originals
because they may lower the vehicle's GVWR and GAWR limitations. Replacement
tires with a higher limit than the orig inals do not increase the GVWR and GAWR
limitations.
Never exceed the GVWR or the GAWR specified on the certification label.
