2015 MAZDA MODEL MX-5 MIATA weight

Black plate (358,1)
Tires
For reasons of proper performance, safety,
and better fuel economy, always maintain
recommended tire inflation pressures and
stay within the recommended load limits
and weight distribution.
WARNING
Using Different Tire Types:Driving your vehicle with different
types of tires is dangerous. It could
cause poor handling and poor
braking; leading to loss of control.
Using Wrong-Sized Tires: Using any other tire size than what is
specified for your Mazda (page 10-7)
is dangerous. It could seriously affect
ride, handling, ground clearance, tire
clearance, and speedometer
calibration. This could cause you to
have an accident. Use only tires that
are the correct size specified for your
Mazda.
qTire Inflation Pressure
WARNING
Always inflate the tires to the correct
pressure:
Overinflation or underinflation of
tires is dangerous. Adverse handling
or unexpected tire failure could result
in a serious accident.
Refer to Tires on page 10-7.
Use only a Mazda-genuine tire valve
cap: Use of a non-genuine part is
dangerous as the correct tire air
pressure cannot be maintained if the
tire valve becomes damaged. If the
vehicle is driven under this condition,
the tire air pressure will decrease
which could result in a serious
accident. Do not use any part for the
tire valve cap that is not a Mazda-
genuine part.

14. SAFETY WARNING
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 rating. 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 width of the tire in millimeters. This three-digit number gives the
width in millimeters of 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 two-digit number indicates the tire's ratio of height to width.
R
“R” is the tire construction symbol. R indicates “Radial ply construction ”.
15
“15 ”is the wheel rim diameter in inches.
95
“95 ”is the Load Index. This two-or three-digit number indicates how much weight each
tire can support.

H
“H ”is the speed rating. The speed rating denotes the maximum speed for which the use of
the tire is rated.
Letter Rating Speed Rating
Q 99 mph
R 106 mph
S 112 mph
T 118 mph
U 124 mph

*mph
Y 186*mph
* For tires with a maximum speed capability over 149 mph, tire manufacturers sometimes use the letters ZR. For tires with a maximum speed capability over 186 mph, tire manufacturers always use the letters ZR.
MS or M/S: Mud and Snow
AT: All Terrain.
AS: All Season. The “M
S” or“M/S ”indicates that the tire has some functional use in
mud and snow.
U.S. DOT Tire Identification Number (TIN)
This begins with the letters “DOT ”which indicates the tire meets all federal standards. The
next two numbers or letters are the plant code where it was manufactured, and the last four
numbers represent the week and year the tire was manufactured. For example, the numbers
457 means the 45st week of 1997. After 2000 the numbers go to four digits. For example,
the number 2102 means the 21th week of 2002. The other numbers are marketing codes
used at the manufacturer's discretion. This information is used to contact consumers if a tire
defect requires a recall.
Tire Ply Composition and Materials Used
The number of plies indicates the number of layers of rubber-coated fabric in the tire. In
general, the greater the number of plies, the more weight a tire can support. Tire
manufacturers also must indicate the tire materials, which include steel, nylon, polyester,
and other.
Maximum Load Rating
This number indicates the maximum load in kilograms and pounds that can be carried by
the tire.
Maximum Permissible Inflation Pressure
This number is the greatest amount of air pressure that should ever be put in the tire under
normal driving conditions.

Vehicle Loading
WARNING
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 determining your vehicle's weight ratings,
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 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 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 vehicle including a full tank of fuel and all
standard equipment. It does not include passengers, cargo, or optional equipment.
Vehicle Curb Weightis the weight of your new vehicle when you picked it up from your
dealer plus any aftermarket equipment.
PAYLOAD
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.
