TIRE SUPPORT (Leveling)
Since motorhomes may sit for long periods of time it is important to properly support
the tires if blocks are used for leveling.
The tire manufacturer for your RV provides a Recreational Vehicle Tire Guide with
each Freightliner chassis that is passed along to you in the Airstream Owner’s Packet.
Please take the time to read it as it has information on the loading, weighing, care, and
inflation of your RV and its tires.
CAUTION: Extreme care must be taken to ensure that the tires are fully supported
when using blocks to level motorhomes and/or RV’s. The load on the tire should be
evenly distributed on the block and in the case of duals, evenly distributed on blocks
for both tires. If not property done, the steel cables in the sidewall of the tires may be
damaged and could lead to premature fatigue of the sidewall. See tire warnings on
page C-4
The CORRECT methods are shown in Figure 1. Please note that the blocks are wider
than the tread and longer than the tire’s footprint. This provides maximum support to the
tires and assures that the load is evenly distributed throughout the tire’s footprint area.
