T115/70D16 90M 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.
T
Indicates a tire that may be installed 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 three-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.
70
“70” is the aspect ratio. This t wo-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.

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 inc reases 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, rel ease 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.

This section will guide you in the proper loading of your vehicle and/or trailer, to keep your
loaded vehicle weigh t within its design rating capability, with or without a trailer. Properly
loading your vehicle will provide maximum return of vehicle des ign performance. Before
loading your vehicle, familiarize yourself with the following t erms for determining your
vehicle's weight ratings, with o r without a trailer, from the vehicle's Safety Certification
Label and Tire and Load Information Label:

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 failu re, handling or steering problems, irregular tire
wear, tire failure or other damage.
Overloading makes a vehicle harder to drive an d 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 th e vehicle's weight ratings from the vehicle's
Safety Certification and Tire and Load Information labels.
Base Curb Weight is the weight o f the vehicle including a full tank of fuel and all
standard equipment. It does not i nclude passengers, cargo, or optional equipment.

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

Payload is the combination weight of cargo and passengers that the veh icle is designed to
carry. The maximum payload for your vehicle can be found on the Tire and Load
Information label on t he 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 l abel 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 accura te.

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

The cargo weight limit decreases depending on the number of veh icle 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 exc eed” 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
Certification Label located on the driver's door frame or door pillar. The total load on
each axle must never exceed its GAWR.

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 fu lly loaded trailer.

GCWR (Gross Combination Weight Rating) is the maximum allowable weight of the
vehicle and the loaded trailer - including all cargo and passen gers - 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 shou ld 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 o ptions, 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 fi fth-wheel trailer, multiply by
0.15 and 0.25 to obtain a proper king pin load range of 1,725 t o 2,875 lbs.
WA R N I N G
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 load carrying capacities than the originals because
they may lower the vehicle's GVWR and GAWR limitations. Replacement tires with a higher
limit than the originals do not increase the GVWR and GAWR limitations.
Never exceed the GVWR or the GAWR specified on the certification label.
