Does one seal one's tires?

[Noah <sitz@xxxx>]

So, the tires on the left side of #2867 are hemorraging air (the front
worse that the rear). Analysis reveals that the air is seeping through
between the tire and the rim. The shop has suggested unmounting the tires,
and remounting them with some sealent to keep the air seeping through. Is
this good advice, good advice if you don't care about your wheels,
or Something Else(patent pending)?
