▼Replacing a Wheel
WARNING
Always use wheels of the correct size on
your vehicle:
Using a wrong-sized wheel is dangerous.
Braking and handling could be
affected,
leading to loss of control and an accident.
CAUTION
A wrong-sized wheel may adversely affect:
 Tire fit
 Wheel and bearing life
 Ground clearance
 Snow-chain clearance
 Speedometer calibration
 Headlight aim
 Bumper height
 Tire Pressure Monitoring System
NOTE
When replacing a wheel, make sure the
new one is the same as the original
factory wheel in diameter, rim width,
and offset (inset/outset).
For details, contact an Authorized
Mazda Dealer.

Proper tire balancing provides the best
riding comfort and helps reduce tread
wear. Out-of-balance tires can cause
vibration and uneven wear, such as
cupping and flat spots.

Steering becomes difficult.
The vehicle begins to vibrate
excessively.
The vehicle pulls in one direction.
If you have a flat tire, drive sl owly to a
level spot that is well off the road and out
of the way of traffic to change the tire.
Stopping in traffic or on the shoulder of a
busy road is dangerous.
WARNING

jack.
Never allow anyone inside a vehicle
supported by a jack:
Allowing someone to remain in a vehicle
supported by a jack is dangerous. The
occupant could cause the vehicle to fall
resulting in serious injury.
NOTE
Make sure the jack is well lubricated
before using it.
1. Park on a hard, le vel surface off the

brake.
2. Shift into Park (P ) and turn off the
engine.
3. Turn on the hazard warning flasher.
4. Have passengers get out of the vehicle and away from the vehicle and traffic.
5. Remove any luggage, the jack, tools, and spare tire (page 7-3).
6. Block the wheel diagonally opposite the flat tire. When blocking a wheel,
place a tire block both in front and
behind the tire.
NOTE
When blocking a tire, use rocks or
wood blocks of sufficient size if
possible to hold the tire in place.

P215/65R15 95H is an example of a tire size and load index rating. Here is an explanation
of the various components of that tire size and load index rati ng. Note that the tire size and
load index rating may be different from the example.
P
Indicates a tire that may be installed on cars, SUVs, minivans and light trucks as designated
by the Tire and Rim Association (T&RA).
NOTE
If your tire size does not begin with a letter this may mean it is designated by either ETRTO
(European Tire and Rim Technical Organization) or JATMA (Japan Tire Manufacturing
Association).
215
“215” is the nominal w idth of the tire in millimeters. This thr ee-digit number gives the
width in millimeters o f the tire from sidewall edge to sidewall edge. In general, the larger
the number, the wider the tire.
65
“65” is the aspect ratio. This t wo-digit number indicates the t ire's ratio of height to width.
R
“R” is the tire construction symbol. R indicates “Radial ply co nstruction”.
15
“15” is the wheel rim diameter in inches.
95
“95” is the Load Index. This two-or three-digit number indicate s how much weight each tire
can support.

Traction: The traction grades, from highest to lowest are AA, A, B, and C. The grades
represent the tire's ability to stop on wet pavement as measure d under controlled conditions
on specified government test surfaces of asphalt and concrete. A tire marked C may have
poor traction performance.
Temperature: The temperature grades are A (the highest), B and C, represent ing the tire's
resistance to the generation of h eat and its ability to dissipate heat when tested under
controlled conditions on a specified indoor laboratory test wheel.
Snow Tires
In some heavy snow areas, local governments may require true sn ow tires, those with very
deeply cut tread. These tires should only be used in pairs or p laced on all four wheels. Make
sure you purchase snow tires that are the same size and constru ction type as the other tires
on your vehicle.
SAFETY WARNING
The following safety warning appears on the tire's sidewall.
SERIOUS INJURY MAY RESULT FROM:
EXPLOSION OF TIRE/RIM ASSEMBLY DUE TO IMPROPER MOUNTING-MATCH
TIRE DIAMETER TO RIM DIAMETER; NEVER EXCEED 40 psi (275 kPa) TO SEAT
BEADS-ONLY SPECIALLY TRAINED PERSONS SHOULD MOUNT TIRES.
TIRE FAILURE DUE TO UNDER-INFLATION/OVERLOADING/
