That's good advice except it's not usable advice unless you actually think the plug-and-then-patch repairs I made are "a disaster waiting to happen".
It's like saying "don't run with scissors", which is great advice, but essentially not useful advice.
What I'm looking for is useful advice, particularly with respect to my technique. I agree with you that a single-piece patch-plug is superior to my two piece arrangement but other than that, what do you see "unsafe" about my plug-and-then-patch method?
The whole point is to find out if this method is a safe patch.
To help you advise me, I provided plenty of pictures of the plug and then patch which, I think, is a valid patch [except for the tread wear (which is a separate issue unrelated to the patch itself)].
Here is what is underneath the patch:
Here is the final repair on the inside (using a big patch):
Here is the final repair on the inside (using a small patch):
Other than the treadwear, did you see anything unsafe in my patch technique?
a. Location of patch b. Patch materials c. Patch technique
Or is it all safe?
