If air wrenches are used they must be periodically calibrated for the proper torque output. Use a torque
wrench to check the air wrench output and adjust the line pressure for the correct torque.
Storage of Tires - Long Term
A cool, dry garage with a sealed cement floor is the preferred method of storage. Tires stored outside may
prematurely age.
Prior to Storage:
Thoroughly clean the tires.
Unload the motorhome to reduce weight on the tires.
Ensure the surface is reasonably level, firm, clean and has good drainage.
Inflate the tires to the maximum inflation pressure as indicated on the Federal Identification Tag.
During Storage:
Cover the tires to block direct sunlight.
Periodically ensure tires are at proper pressure.
Move the motorhome every three months to prevent cracking in bulge areas, as well as flat spotting from
prolonged sidewall strain and tread deflection.
Removal from Storage:
Before removing the motorhome from long-term storage thoroughly
inspect
each tire’s tread area and air
pressure. If the tires have lost air during storage, inflate them to the correct pressure.

P
roper weight distribution, load management and operating within
established limitations will aid in safe and enjoyable travel. The information
in this section outlines guidelines and provides information on the proper
techniques for weighing to accurately determine total weight, axle weights,
balance and tire inflation pressure. According the National Highway Traffic
Safety Administration, most tire failures are a result of under-inflated tires.
Load management, weight distribution and properly inflated tires are the
responsibility of the operator. The motorhome must be weighed in a loaded,
ready to travel condition to correctly determine how much weight is placed on
each wheel position, then added to determine the overall weight upon a single
axle. This may require one or more adjustments and the motorhome subsequently weighed again to verify proper
and adequate adjustments. The first thing to determine is the maximum allowable weight of the motorhome. This
information is found on the Federal Certification Label located adjacent to the driver seat under Gross Vehicle
Weight Rating. This is the maximum allowable gross weight and cannot be exceeded.
Federal Certification and Weight Labels:
There will be two Federal Certification build labels and as many as three Federal Weight label(s) affixed to the
motorhome.
