Tire Age
WARNINGS
Tires degrade over time
depending on many factors
such as weather, storage
conditions, and conditions of use
(load, speed, inflation pressure)
the tires experience throughout
their lives.
In general, tires should be
replaced after six years
regardless of tread wear.
However, heat caused by hot
climates or frequent high loading
conditions can accelerate the
aging process and may require
tires to be replaced more
frequently.
You should replace your
spare tire when you replace
the road tires or after six years due
to aging even if it has not been
used.

LT-metric or all-season versus
all-terrain) as those originally
