Yesterday, for practice in dismounting, patching, and remounting, I patched
these 5 tires above, which a friend and I had lying around.

For the purpose of this thread, we can ignore the tread wear since the
question is being asked about how to decide when a nail hole is too close
to the sidewall.

I guess the first question is *WHY* we can't patch next to the sidewall.
Is it that the patch won't hold? Why?
Is it that the patch will flex too much?
Or is it that the belts are damaged and they will break?


Those holes are nowhere near the sidewall to be off concern. I've
patched/plugged holes much closer than that. In fact, I plugged a hole a
few mm from the corner and it held up for the remaining tread life.

If the patch/plug job is well prepped and well applied, there shouldn't
be a reason it will fail.
