Breaking-in the new 77FC on Thanksgiving

[Pete Masterson]

The tires can degrade from the inside while the exterior looks OK --
but the tire isn't sound. RVs rarely wear out tires, but rather they
time out. Most tire manufacturers suggest replacing tires after 5 to
7 years -- check the DOT dates on the tires.

Obvious checking or cracking in the sidewall is a sure sign of
imminent tire failure, but the visible sidewall may have been treated
with cosmetic preservatives (such as Armor All) -- but the back side
of the tire was not -- there is a possibility that the tire looks OK
but you can't see the parts that have deteriorated.

The only way to be certain that an older tire is OK is to unmount it
and inspect it on the inside and the outside. Often, an older tire
will crumble as it's being removed from the rim ... proving the point
about its condition.

If you are located where you can get to a Les Schwab tire store, take
your 'bird there for both good prices and good service.
