I'm just wondering. During my scheduled tire tread inspection, I found several pieces of broken glass embedded in the tire, two pieces of small and sharp metal debris, and one strand of steel wire. Fortunately, the anti-puncture belt was not penetrated and the tire is otherwise, perfectly fine.

Could I have picked those up from the short gravel paths I take? Most of my rides are over pavement.

Ninety nine times out of a hundred, the piece of wire you find stuck in your bike tire one resided inside an automobile tire's steel belting. Unless you're fond of riding through construction sites, the wire most likely came from a place cars frequent: the road.

How thick are these wires? The ones I found so far stuck in my tires looks like stainless steel wires as thin as individual wire strands in brake and shifter cables of bicycles

Ofc, if they are bike cable wires, they probably came from the road too.

Definitely from a car tire.

Nearly everything on the road is from cars. On pavement this includes bungee cords, broken glasses, random shoes, diapers, broken kitchen appliances, bottles, cans, plastic bags, and couches.

On gravel, I see occasional pieces of trim, random nuts and bolts, and very occasionally something from other outdoor pursuits (carabiner, camp chairs, or tent parts). Overall much easier on your tires.

I think the big hazard on gravel is glass shards. Wire would be somewhat less common, although one of the closed roads in the nearby forest had tire tracks last summer, so who knows?

As stupid as this may sound, most of the broken glass on our road are from people throwing bottles at the side of the roads. I think such behavior (not culture nor tradition, simply anti-social behavior or something) is common in poor neighborhoods. Most neighborhoods in this part of the world are poor.

These glass shards are much sharper and pointed than those that came from cars. The tempered glass used in cars tend to break in blunt and relatively rounded shapes.

Many of our gravel roads handle vehicular traffic, although traffic is light. It's harder to see stuff in gravel.

Sorry, I can't give a Philippines specific answer.

It makes sense and I certainly see plenty of broken bottles in the ditches in the US too.
