[TR] OT? Replacing Temp spare tires?

I think they are less of a concern, because spare tires are typically stored
away from daylight and ozone, and are supposed to be used only for short
trips at low speeds.  But Bridgestone/Firestone recommends they be replaced
after 10 years; likely other tire makers do as well.

Surely someone can order them for you.  But as cheap as used ones are, I
don't see the point.

I don't know what a tire shop would have to say about it.  But I dismounted
and remounted mine using a cheap manual tire changer from HF, with no
trouble at all.   And the stock TR3 wheel was only slightly wider than the
original wheel, so no trouble with seating the bead either.

I've even put it to the test, driving some 40 miles home after ruining a
tire, at speeds of 70-80 mph.  Worked perfectly.
