Re: [Diesel-RVs] Re: Vapor Barriers Beneath Tires

Any time I see a statement like 'no mfg has ever recommended' I become a
skeptic.. You can see what the mfgs really say at these links or the direct
quote from Michelin in the next paragraph. I also have an copy of the pdf
files should someone want it emailed directly.

Per Michelin,

Tire life is 10 years with annual inspections required after 5 years (per
Michelin not me). So it is possible to get more than 5 years out of your rv
tires if you follow the mfg storage, inflation, and care recommendations.
(Probably not completely possible or adviseable to go that long but with
proper care life can be extended beyond 5 years is the message). Also in
the tire care bulletin and this is a direct quote 'If you must store your
rv, a cool, dry, sealed garage is your best bet. Also, some storage surfaces
can cause a tire to age faster. That's why Michelin recommends placing a
barrier (cardboard, plastic, or plywood) between your tire and storage
surface.' You may read this in the service bulletins at the michelin
website. There are several pdf files that can be viewed or downloaded
regarding tire replacement, loading, care, etc.

Per Goodyear, http://www.goodyear.com/rv/tirecare/tire_storage.html

The best place to store tires is a clean, cool, dry, sunless area away from
strong air currents. Even though the rubber used to make tires is formulated
to resist the effects of sunlight, ozone, and water, the life of a tire can
be extended if exposure to these elements is minimized during storage.

· Stack tires flat so that the bottom tire will maintain its shape

· Wrap each tire with an opaque polyethylene covering to minimize the
effects of oxygen and ozone. Most Goodyear retailers have storage bags made
specifically for this purpose

· If tires are being stored outdoors, they should be raised off the storage
surface

· If tires are stored while mounted on rims, they should be inflated to 10
psi

· If they are put in storage during warm weather, the initial inflation
pressure should be about 15 psi to offset the pressure drop during cold
weather months

HOW NOT TO STORE YOUR TIRES

· Don't store tires in an area that is wet, oily or greasy

· Don't store tires where they are subjected to direct sunlight or extreme
temperatures

· Don't store tires near electric motors or other ozone-generating sources

· Don't store tires on black asphalt or other heat-absorbent surfaces

· Don't store tires on or adjacent to highly reflective surfaces such as
sand or snow

STORING YOUR VEHICLE WITHOUT REMOVING THE TIRES

Ideally, a vehicle in storage should be placed on blocks to remove all
weight from the tires. If the vehicle cannot be put on blocks, follow these
steps for tire protection:

· Completely unload the vehicle so that minimum weight will be placed on the
tires

· Inflate tires to recommended operating pressure plus 25%. Ensure that the
rim manufacturer's inflation capacity is not exceeded

· Be sure the storage surface is firm, clean, well drained and reasonably
level

· Avoid moving the vehicle during extremely cold weather

· Move the vehicle at least every three months to prevent ozone cracking in
the tire bulge area, as well as "flat-spotting" from the prolonged strain of
sidewall and tread deflection

Adjust inflation before putting the vehicle back into service
