quality is not significant. When inflation pressure requirements are not met, tire
durability and optimum operation can be affected.
WEIGHING YOUR TRAVEL TRAILER OR TOWED VEHICLE
Since a trailer or towed vehicle adds to the load on your RV’s tires, it is crucial to
properly weigh towed vehicles. A travel trailer should first be weighed with the
tongue, while detached from the pulling vehicle. The actual weight of the trailer
must be less than or equal to the GVWR for safe operation, otherwise contents
must be removed until the weight is within maximum GVWR limitations. The
weight of the complete, attached trailer, excluding the towing vehicle, must
also be taken. Each wheel should be weighed while still attached to the towing
vehicle, and the individual wheel positions on the towing vehicle should be
weighed and checked for overload as well.
If you determine that the loading of your vehicle’s tires are uneven, the actual
weight of the trailer on each tire must be less than or equal to its maximum
load capacity for safe operation, otherwise contents must be removed until the
weight is within maximum load limitations.
TIRE CARE
Tires are a very precisely engineered product designed for specific applications
and use. The tire functions as the sole contact between the vehicle and the
road. Therefore, it must provide several different functions in order for your
tow and recreational vehicle to handle properly. Most important are traction
while moving, grip when steering or stopping, and a comfortable ride for you
and your passengers. The Tires on your recreational vehicle are designed for
highway use and must be properly maintained in order to maximize tire life, as
well to provide a safe mode of transportation. Always keep your tires clean and
properly inflated.
Correct tire inflation is a key component in tire care. The recommended inflation
pressures for your tires are indicated on the certification label and in your
owner’s manual. Since RVs can be loaded with many different configurations,
the load on each tire will vary. For this reason, air pressure should be checked
based on the load on each individual tire. Cold Inflation Pressure should be
adjusted to handle the maximum tire load, and all tires on the axle should carry
the same inflation pressure. COLD TIRE INFLATION PRESSURE is the tire
pressure checked in the morning before you drive more than a few miles or
before rising ambient temperatures or the sun’s radiant heat affects it.
