DANGEROUS TIRES

At the Mount Hood Roundup, Wes Caughlan warned us to get rid of the
Michelin XCA load range-D tires. Since then I have seen several coaches
still running the tires. Owners still running these tires risk expensive
damage to their coaches. When the fires blow out they damage the lower
fiberglass body parts. Even though the fires are warranted for four
years, they may fail much sooner than that. Eugene Slanter had two of
these tires blow out through the tread while the fires were mounted on
his spare fire carrier!. The tires had less than 1500 miles and were
less than one-year old. The age of the tires can be determined by
checking the three-digit code on the sidewall. The first two numbers
indicate the week the fires were manufactured, and the third indicates
the year (for example 345 would be week 34 in 1985).

Scarey!!!!.
