I just wish I could find a tire with steel impregnated rubber treads for my utility bike. DOES NOT ANY ONE MAKE A TIRE WITH SCINTILLATED RUBBER????
and the newest one:
this is what started this bulge a puncture that would have left anyone else stranded.

Looking at your tires, it looks like you have a combination of over-worn tires and cheap construction of the tires.
I suppose road bike tires are a different class than MTB and BMX tires, but one can get maybe 5000 miles or so on a road bike tire starting with pretty thin tread.
I'm of the opinion that the bigger the tire with the deeper the tread, the bigger the holes
My 25mm Marathon tire that I've set aside picked up a deep gash the first couple of days of use

I booted it and it survived another 1000 miles, but my boots gave me problems
On the other hand, my 25mm Origin8 Elimin8er tires are wearing mighty thin, and still going and going and going. I wore into the sub-tread about 2000 miles ago. And, what is very thin rubber left seems to be better at rejecting glass
I've got moped tires on my heavy cargo trailer, and couldn't be happier with them. But, I don't pull it a lot since it is rather heavy

They are 16"x3 bicycle size for Schwinn 16x3 rims (12" inner diameter).
Ok, my Schwinn 16x3 OEM tires are rated at 35 PSI. My Moped 16x3 (12" rim) tires are rated at 40 PSI. There is just no comparison between the two. Even the tubes are heavier duty. I think I've had either 50 or 60 psi in the moped tires, and wouldn't worry about moderate over-inflation with a bicycle application. At least mine are STURDY TIRES.
