Maximum Permissible Inflation Pressure is the greatest amount of air pressure that
should ever be put in the tire under normal driving conditions.
Tire Safety Tips
Check tire pressure regularly (at least once a month), including the spare.
Inspect tires for uneven wear patterns on the tread, cracks, foreign objects, 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 and Loading Placard or User’s
Manual for the maximum recommended load for the vehicle.
F. LOADING THE TRAILER
Improper trailer loading causes many accidents and deaths. To safely load a trailer, you
must consider:
Overall load weight;
Load weight distribution;
Proper tongue weight; and
Securing the load properly.
To determine that you have loaded the trailer within its rating, you must consider the
distribution of weight, as well as the total weight of the trailer and its contents. The
trailer axles carry most of the total weight of the trailer and its contents (Gross Vehicle
Weight or “GVW”). The remainder of the total weight is carried by the tow vehicle
hitch. It is essential for safe towing that the trailer tongue and tow vehicle hitch carry the
proper amount of the loaded trailer weight, otherwise the trailer can suddenly sway
