Steps for Determining Correct Load Limit—Trailer
Determining the load limits of a trailer includes more than understanding the load limits of the tires alone. On all trailers there is a Federal certification / VIN label that is located on the forward half of the left (road) side of the unit. This certification / VIN label will indicate the trailer’s Gross Vehicle Weight Rating (GVWR). This is the most weight the fully loaded trailer can weigh. It will also provide the Gross Axle Weight Rating (GAWR). This is the most a particular axle can weigh. If there are multiple axles, the GAWR of each axle will be provided.
If your trailer has a GVWR of 10,000 pounds or less, thereis a vehicle placard located in the same location as the certification label described above. This placard provides tire and loading information. In addition, this placard will show a statement regarding maximum cargo capacity. Cargo can be added to the trailer, up to the maximum weight specified on the placard. The combined weight of the cargo is provided as a single number. In any case, remember: the total weight of a fully loaded trailer can not exceed the stated GVWR.
For trailers with living quarters installed, the weight of water and propane also need to be considered. The weight of fully filled propane containers is considered part of the weight of the trailer before it is loaded with cargo, and is not considered part of the disposable cargo load. Water however, is a disposable cargo weight and is treated as such. If there is a fresh water storage tank of 100 gallons, this tank when filled would weigh about 800 pounds. If more cargo is being transported, water can be off-loaded to keep the total amount of cargo added to the vehicle within the limits of the GVWR so as not to overload the vehicle. Understanding this flexibility will allow you, the owner, to make choices that fit your travel needs.
When loading your cargo, be sure it is distributed evenly to prevent overloading front to back and side to side. Heavy items should be placed low and as close to the axle positions as reasonable. Too many items on one side may overload a tire. The best way to know the actual weight of the vehicle is to weigh it at a public scale. Talk to your dealer to discuss the weighing methods needed to capture the various weights related to the trailer. This would include the weight empty or unloaded, weights per axle, wheel, hitch or king-pin, and total weight.
Excessive loads and / or underinflation cause tire overloading and, as a result, abnormal tire flexing occurs. This situation can generate an excessive amount of heat within the tire. Excessive heat may lead to tire failure. It is the air pressure that enables a tire to support the load, so proper inflation is critical. The proper air pressure may be found on the certification / VIN label and/or on the Tire Placard. This value should never exceed the maximum cold inflation pressure stamped on the tire.
1.1 Trailers 10,000 Pounds (4536 kg) GVWR or less
(1) Locate the statement “The weight of cargo should never exceed XXX kg or XXX lbs.” on your vehicle’s placard.
(2) This figure equals the available amount of cargo and luggage load capacity.
(3) Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity.
1.2 Trailers over 10,000 Pounds (4536 kg) GVWR
(Note: These trailers are not required to have a tire information placard on the vehicle.)
(1) Determine the empty weight of your trailer by weighing the trailer using a public scale or other means.
This step does not have to be repeated.
(2) Locate the GWVR of the trailer on your trailer’s VIN (Certification) label.
(3) Subtract the empty weight of your trailer from the GVWR stated on the VIN label. That weight is the maximum available cargo capacity of the trailer and may not be safety exceeded. -
Steps for Determining Correct Load Limit—Tow Vehicle
(1) Locate the statement “The combined weight of occupants and cargo should never exceed XXX kg or XXX lbs.” on your vehicle’s placard.
(2) Determine the combined weight of the driver and passengers that will be riding in your vehicle.
(3) Subtract the combined weight of the driver and passengers from XXX kg or XXX lbs.
(4) The resulting figure equals the available amount of cargo and luggage load capacity. For example, if the ‘‘XXX’’ amount equals 1400 lbs. and there will be five 150 lb passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs. (1400–750 (5 × 150) = 650 lbs.)
(5) Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in Step 4.
(6) If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consult the tow vehicle’s manual to determine how this reduces the available cargo and luggage load capacity of your vehicle. -

Tire Safety – Everything Rides On It
The National Traffic Safety Administration (NHTSA) has published a brochure (DOT HS 809 361) that discusses all aspects of Tire Safety, as required by 49 CFR 575.6.
This brochure is reproduced in part below. It can be obtained and downloaded from NHTSA, free of charge, from the following web site: http://www.nhtsa.dot.gov/cars/rules/TireSafety/ridesonit/tires_index.html
Studies of tire safety show that maintaining proper tire pressure, observing
tire and vehicle load limits (not carrying more weight in your vehicle than
your tires or vehicle can safely handle), avoiding road hazards, and
inspecting tires for cuts, slashes, and other irregularities are the most
important things you can do to avoid tire failure, such as tread separation or
blowout and flat tires.
These actions, along with other care and maintenance activities, can also:
- Improve vehicle handling
- Help protect you and others from avoidable breakdowns and accidents
- Improve fuel economy
- Increase the life of your tires
This booklet presents a comprehensive overview of tire safety, including information on the following topics:
- Basic tire maintenance
- Uniform Tire Quality Grading System
- Fundamental characteristics of tires
- Tire safety tips. Use this information to make tire safety a regular part of your vehicle maintenance routine.
Recognize that the time you spend is minimal compared with the inconvenience
and safety consequences of a flat tire or other tire failure.
Safety First–Basic Tire Maintenance
Properly maintained tires improve the steering, stopping, traction, and load-
carrying capability of your vehicle. Underinflated tires and overloaded
vehicles are a major cause of tire failure. Therefore, as mentioned above, to
avoid flat tires and other types of tire failure, you should maintain proper
tire pressure, observe tire and vehicle load limits, avoid road hazards, and
regularly inspect your tires.
Finding Your Vehicle’s Recommended Tire Pressure And Load Limits
Tire information placards and vehicle certification labels contain information
on tires and load limits. These labels indicate the vehicle manufacturer’s
information including:
- Recommended tire size
- Recommended tire inflation pressure
- Vehicle capacity weight (VCW – the maximum occupant and cargo weight a vehicle is designed to carry)
- Front and rear gross axle weight ratings (GAWR – the maximum weight the axle systems are designed to carry).
Both placards and certification labels are permanently attached to the trailer
near the left front.
Understanding Tire Pressure And Load Limits
Tire inflation pressure is the level of air in the tire that provides it with
load-carrying capacity and affects the overall performance of the vehicle. The
tire inflation pressure is a number that indicates the amount of air pressure–
measured in pounds per square inch (psi)–a tire requires to be properly
inflated. (You will also find this number on the vehicle information placard
expressed in kilopascals (kpa), which is the metric measure used
internationally.)
Manufacturers of passenger vehicles and light trucks determine this number
based on the vehicle’s design load limit, that is, the greatest amount of
weight a vehicle can safely carry and the vehicle’s tire size. The proper tire
pressure for your vehicle is referred to as the “recommended cold inflation
pressure.” (As you will read below, it is difficult to obtain the recommended
tire pressure if your tires are not cold.)
Because tires are designed to be used on more than one type of vehicle, tire
manufacturers list the “maximum permissible inflation pressure” on the tire
sidewall. This number is the greatest amount of air pressure that should ever
be put in the tire under normal driving conditions.
Checking Tire Pressure
It is important to check your vehicle’s tire pressure at least once a month
for the following reasons:
- Most tires may naturally lose air over time.
- Tires can lose air suddenly if you drive over a pothole or other object or if you strike the curb when parking.
- With radial tires, it is usually not possible to determine underinflation by visual inspection.
For convenience, purchase a tire pressure gauge to keep in your vehicle.
Gauges can be purchased at tire dealerships, auto supply stores, and other
retail outlets.
The recommended tire inflation pressure that vehicle manufacturers provide
reflects the proper psi when a tire is cold. The term cold does not relate to
the outside temperature. Rather, a cold tire is one that has not been driven
on for at least three hours.
When you drive, your tires get warmer, causing the air pressure within them to
increase. Therefore, to get an accurate tire pressure reading, you must
measure tire pressure when the tires are cold or compensate for the extra
pressure in warm tires.
Steps For Maintaining Proper Tire Pressure
- Step 1: Locate the recommended tire pressure on the vehicle’s tire information placard, certification label, or in the owner’s manual.
- Step 2: Record the tire pressure of all tires.
- Step 3: If the tire pressure is too high in any of the tires, slowly release air by gently pressing on the tire valve stem with the edge of your tire gauge until you get to the correct pressure.
- Step 4: If the tire pressure is too low, note the difference between the measured tire pressure and the correct tire pressure. These “missing” pounds of pressure are what you will need to add.
- Step 5: At a service station, add the missing pounds of air pressure to each tire that is underinflated.
- Step 6: Check all the tires to make sure they have the same air pressure (except in cases in which the front and rear tires are supposed to have different amounts of pressure).
If you have been driving your vehicle and think that a tire is underinflated,
fill it to the recommended cold inflation pressure indicated on your vehicle’s
tire information placard or certification label. While your tire may still be
slightly underinflated due to the extra pounds of pressure in the warm tire,
it is safer to drive with air pressure that is slightly lower than the vehicle
manufacturer’s recommended cold inflation pressure than to drive with a
significantly underinflated tire. Since this is a temporary fix, don’t forget
to recheck and adjust the tire’s pressure when you can obtain a cold reading.
Tire Size
To maintain tire safety, purchase new tires that are the same size as the
vehicle’s original tires or another size recommended by the manufacturer. Look
at the tire information placard, the owner’s manual, or the sidewall of the
tire you are replacing to find this information. If you have any doubt about
the correct size to choose, consult with the tire dealer.
Tire Tread
The tire tread provides the gripping action and traction that prevent your
vehicle from slipping or sliding, especially when the road is wet or icy. In
general, tires are not safe and should be replaced when the tread is worn down
to 1/16 of an inch. Tires have built-in treadwear indicators that let you know
when it is time to replace your tires. These indicators are raised sections
spaced intermittently in the bottom of the tread grooves. When they appear
“even” with the outside of the tread, it is time to replace your tires.
Another method for checking tread depth is to place a penny in the tread with
Lincoln’s head upside down and facing you. If you can see the top of Lincoln’s
head, you are ready for new tires.
Tire Balance And Wheel Alignment
To avoid vibration or shaking of the vehicle when a tire rotates, the tire
must be properly balanced. This balance is achieved by positioning weights on
the wheel to counterbalance heavy spots on the wheel-and-tire assembly. A
wheel alignment adjusts the angles of the wheels so that they are positioned
correctly relative to the vehicle’s frame. This adjustment maximizes the life
of your tires. These adjustments require special equipment and should be
performed by a qualified technician.
Tire Repair
The proper repair of a punctured tire requires a plug for the hole and a patch
for the area inside the tire that surrounds the puncture hole. Punctures
through the tread can be repaired if they are not too large, but punctures to
the sidewall should not be repaired. Tires must be removed from the rim to be
properly inspected before being plugged and patched.
Tire Fundamentals
Federal law requires tire manufacturers to place standardized information on
the sidewall of all tires. This information identifies and describes the
fundamental characteristics of the tire and also provides a tire
identification number for safety standard certification and in case of a
recall.
Information on Passenger Vehicle Tires
Please refer to Figure 30 and the information
following.A- ‘P’ indicates the tire is for
passenger vehicles.
B- 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.
C- This two-digit number, known as the aspect ratio, gives the tire’s ratio of
height to width. Numbers of 70 or lower indicate a short sidewall for improved
steering response and better overall handling on dry pavement.
D- “R” stands for radial. Radial ply construction of tires has been the
industry standard for the past 20 years.
E- This two-digit number is the wheel or rim diameter in inches. If you change
your wheel size, you will have to purchase new tires to match the new wheel
diameter.
F- (Number) This two- or three-digit number is the tire’s load index. It is a
measurement of how much weight each tire can support. You may find this
information in your owner’s manual. If not, contact a local tire dealer. Note:
You may not find this information on all tires because it is not required by
law.
(Letter) The speed rating denotes the speed at which a tire is designed to be
driven for extended periods of time. The ratings range from 99 miles per hour
(mph) to 186 mph. These ratings are listed below. Note: You may not find this
information on all tires because it is not required by law.
Letter Rating | Speed Rating |
---|---|
Q | 99 mph |
R | 106 mph |
S | 112 mph |
T | 118 mph |
U | 124 mph |
H | 130 mph |
V | 168 mph* |
Y | 186 mph* |
*Note: For tires with a maximum speed capability over 149 mph, tire
manufacturers sometimes use the letters ZR. For those with a maximum speed
capability over 186 mph, tire manufacturers always use the letters ZR.
G- U.S. DOT Tire Identification Number. This begins with the letters “DOT” and
indicates that 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 built. For example, the
numbers 3197 means the 31st week of 1997. 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.
H- The “M+S” or “M/S” indicates that the tire has some mud and snow
capability. Most radial tires have these markings; hence, they have some mud
and snow capability.
I- 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 materials in the tire, which include steel, nylon,
polyester, and others.
J- Maximum Load Rating. This number indicates the maximum load in kilograms
and pounds that can be carried by the tire.
K- 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.
Uniform Tire Quality Grading (UTQGS)
Quality grades can be found where applicable on the tire sidewall between
tread shoulder and maximum section width. For example:
TREADWEAR 200 TRACTION AA
Temperature A
All Passenger Car Tires Must Conform to Federal Safety Requirements in
Addition to These Grades
Treadwear
The treadwear grade is a comparative rating based on the wear rate of the tire
when tested under controlled conditions on a specified government test course.
For example, a tire graded 150 would wear one and one-half (11⁄2) times as
well on the government course as a tire graded 100. The relative performance
of tires depends upon the actual conditions of their use, however, and may
depart significantly from the norm due to variations in driving habits,
service practices and differences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are AA, A, B, and C. Those grades
represent the tire’s ability to stop on wet pavement as measured under
controlled conditions on specified government test surfaces of asphalt and
concrete. A tire marked C may have poor traction performance.
Warning: The traction grade assigned to this tire is based on straight-
ahead braking traction tests, and does not include acceleration, cornering,
hydroplaning, or peak traction characteristics.
Temperature
The temperature grades are A (the highest), B, and C, representing the tire’s
resistance to the generation of heat and its ability to dissipate heat when
tested under controlled conditions on a specified indoor laboratory test
wheel. Sustained high temperature can cause the material of the tire to
degenerate and reduce tire life, and excessive temperature can lead to sudden
tire failure.The grade C corresponds to a level of performance which all
passenger car tires must meet under the Federal Motor Safety Standard No. 109.
Grades B and A represent higher levels of performance on the laboratory test
wheel than the minimum required by law. Warning: The temperature grade for
this tire is established for a tire that is properly inflated and not
overloaded. Excessive speed, underinflation, or excessive loading, either
separately or in combination, can cause heat buildup and possible tire
failure.
Additional Information on Light Truck Tires*
Tires for light trucks have other markings besides those found on the
sidewalls of passenger tires. See Figure 31 and the information
following.A- The “LT” indicates the tire is for light
trucks. An “ST” is an indication the tire is for trailer use only.
B- Load Range. This information identifies the tire’s load- carrying
capabilities and its inflation limits.
C- Maximum Load Dual. This information indicates the maximum load and tire
pressure when the tire is used as a dual, that is, when four tires are put on
each rear axle (a total of six or more tires on the vehicle).
D- The “M+S” or “M/S” indicates that the tire has some mud and snow
capability. Most radial tires have these markings; hence, they have some mud
and snow capability.
E- This information indicates the maximum load and tire pressure when the tire
is used as a single.
Note: Maximum load is presented in kilograms and pounds (kg/ lbs).
Maximum tire pressure is presented in kilopascals and pounds per square inch
(kPa/psi) for when the tire is cold.
Tire Safety Tips
Preventing Tire Damage**
- Slow down if you have to go over a pothole or other object in the road.
- Do not run over curbs of foreign objects in the roadway, and try not to strike the curb when parking.
Tire Safety Checklist
- Check tire pressure regularly (at least once a month), including the spare.
- Inspect tires for cracks, foreign objects, uneven wear patterns on the tread, or other signs of wear or trauma.
- Remove bits of glass and foreign objects wedged in the tread.
- Make sure your tire valves have valve caps.
- Check tire pressure before going on a long trip.
- Do not overload your vehicle. Check the tire information placard or owner’s manual for the maximum recommended load for the vehicle.
