Tire Information Label Excessive loads and or under inflation cause tire over loading and as a result abnormal tire flexing occurs This situation can generate an excessive amount of heat and 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 VIN label and or on the Tire Information Label This value should never exceed the maximum cold inflation pressure stamped on the tire Triple L Trailer 1 3 SECTION 1 SAFETY PRECAUTIONS 1 VIN Label 2 Tire Information Label Figure 1 1 VIN Label amp Tire Information Label Unsafe Load Distribution Uneven load distribution can cause tire wheel axle or structural failure Be sure your trailer is properly loaded A proper weight distribution is equal right to left and cre ates a tongue weight that is in the proper range for stable trailer handling between 10 15 of the total weight of the cargo and the trailer Towing stability also depends on keeping the center of gravity as low as possible Load heavy items on the floor and over the axles but do not exceed the axle load rating GAWR When loading addi tional items be sure to maintain even side to side weight distribution and proper tongue weight A WARNING MAKE CERTAIN THAT THE TONGUE WEIGHT IS WITHIN THE ALLOWABLE RANGE BE SURE TO DISTRIBUTE THE LOAD FRONT TO REAR TO PROV
