TIRE SUPPORT
Since motorhomes may sit for long periods of time it is important to properly support the tires if
blocks are used for leveling.
The following information is provided by the Michelin Technical Group.
Extreme caution 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.
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.
