Tire Safety Information
Steps for Determining Correct Load Limit
- Locate the statement “The weight of cargo should never exceed 578 kg or 1275 lbs” on your tire information placard.
- This figure equals the available amount of cargo and luggage load capacity.
- 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.
General Tire Information
- Tire inflation pressure is the level of air in the tire that provides the 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 a tire
requires to be properly inflated. Since 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.
- Improper inflation is the main cause of tire failure. Excessive loads and/or under inflation cause tire overloading,
which leads to abnormal tire flexing. Check the cold tire inflation pressures at least once a week for proper inflation
levels.
o
The proper air pressure may be found on the Certification/VIN label and/or the Tire Information placard.
- High speed towing in hot conditions degrades the life of the tires. The internal heat generated from high speeds
breaks down the tire’s internal structure. It is recommended to drive at moderate speeds.
- If the trailer is stored for an extended period of time, the tires should be fully inflated to the maximum rated pressure.
The trailer jet should be stored in a cool, dry place. Use tire covers to protect the trailer tires from the harsh effects of
the sun.
Tire Maintenance
Checking Tire Pressure
- The recommended tire inflation pressure that vehicle manufacturers provide reflects the proper PSI when a tire is
cold. A cold tire is one that has not been driven on for at least three hours. Since driving raises the tires temperature,
the internal air pressure also increases. To prevent inflated tire readings, the tire must be measured when cold.
Maintaining Proper Tire Pressure
a. Locate the recommended tire pressure on the vehicle’s tire information placard, certification label, or in the owner’s
manual.
b. Record the tire pressure of all tires.
c.
If the tire pressure is too high in any tires, slowly release air by gently pressing on the tire valve stem with the edge
of your tire gauge until the correct pressure is reached.
d. If the tire pressure is too low, note the difference between the measured tire pressure and the correct tire pressure.
Add the missing pounds of air pressure to each tire that is under inflated.
e. Check all the tires to make sure they have the same air pressure
Note: If the tires are warm due to driving, but testing confirms under inflation, fill the tire to the recommended cold
inflation pressure. While the tire may be slightly under inflated due to extra pressure in the warm tire, it is safer to drive
a slightly under inflated tire then to drive a significantly under inflated tire. Since this is a temporary fix, the tire must be
re-checked and adjusted once a cold reading can be obtained.
Tire Size and Tread
- Tires should be replaced when the tread is worn down 1/16 of an inch.
- Treadwear indicators on the bottom of the tire can be used as a guide. The indicators are raised sections spaced
intermittently in the bottom of the tread groves. If they appear even with the outside of the tread, the tire should be
replaced.
- Replacement tires should be the same size as the original tires. To prevent error and maintain safety, it is
recommended that all replacement parts be purchased through Spartan Tool LLC.
