The radial tire patch is a re-enforced patch - a tube patch is not -
it needs to stretch with the tube.

But how do you know a radial patch by sight and look and feel?
Is there a way to tell?

I have not seen a "non-radial" tire
carcass patch in years.

I'm not sure what that means.
Are you saying all patches sold in the auto parts stores are radial?

A radial tire needs to be patched "all the way
through" - plug the hole and seal the liner. Combination patches are
best. I have been "guilty" of patching nail punctures with a simple
plug - and gotten away with it.

Your advice is fair that you have to patch the inside, seal the hole, and
ensure the belts aren't sharp. Nonetheless, both of us have gotten away
with "just" a plug and just a patch.

The reamer in a tire shop is usually mounted in an air operated "die
grinder" or drill.

I figured a "drill" might tear up the belts a bit too much though.
But the bit they use in tire shops seems like something we all should have
at home because it makes a screw puncture a standard size and it smoothes
out the belt tear I would think.

An alternative to a "plugpatch" is installing a plug, then buffing the
interior and putting a patch over it.

I like that idea, in that you install the standard plug, and then you cut
and grind it flush, and then patch over that to protect the inside.

I need to find where to get, for homeowners, small amounts of that black
goop they paste over the patch when they're done, at a tire shop.

I'm sure I can find industrial sizes, but we patch one tire a year, so,
small amounts are all that is needed (a few ounces).

No patch within an inch of the edge of the tread, or in the sidewall.

Yup. Too much flexing going on there.
