2021 MAZDA MODEL 6 tire size

1. Temporary tires
2. Nominal width of tire in millimeters
3. Ratio of height to width (aspect ratio)
4. Diagonal
5. Rim diameter code
6. Load index & speed symbol
T115/70D16 90M is an example of a tire size and load index rating. Here is an explanation
of the various components of tha t tire size and load index rating. Note that the tire size and
load index rating may be different from the example.
T
Indicates a tire that may be ins talled on cars, SUVs, minivans and light trucks as designated
by the Tire and Rim Association (T&RA).
11 5
“115” is the nominal width of the tire in millimeters. This thr ee-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.
70
“70” is the aspect ratio. This two-digit number indicates the t ire's ratio of height to width.
D
“D” is the tire construction symbol. D indicates “diagonal ply construction”.
16
“16” is the wheel rim diameter in inches.
90
“90” is the Load Index. This two-or three-digit number indicate s how much weight each tire
can support.
M
“M” is the speed rating. The speed rating denotes the maximum s peed for which the use of
the tire is rated.

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 vehicle is maintained a t the recommended pressure.
You should check the tire pressure regularly to insure that the proper inflation pressure is
maintained.
Refer to Tires on page 9-8.
NOTE
Tire pressures listed on the vehicle placard 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.

WA R N I N G
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 incr eases 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 pushing 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, b ulges, cracks or other
irregularities.
▼ Glossary of Terms
Tire Placard:
A label indicating the OE tire sizes, recommended inflation pr essure, and the
maximum weight the vehicle can carry.
Tire Identification Number (TIN): A number on the sidewall of each tire providing
information about the tire brand and manufacturing plant, tire size, and date of manufacture.
Inflation Pressure: A measure of the amo unt 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 fr ont door.

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 sy stem which could result in vehicle damage.
This section will guide you in the proper loading of your vehic le, to keep your loaded
vehicle weight within its desig n rating capability. Properly loading your vehicle will provide
maximum return of vehicle design performance. Before loading yo ur vehicle, familiarize
yourself with the following term s for determining your vehicle's weight ratings, from the
vehicle's Safety Certification La bel 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 overl oading, 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.
