Two minutes to remove a tire that could cost a life.
Yes, but more likely to cost the life of someone that tries to roll a heavy tire off the road, than the life of someone inside the safety cage of a car body....
The only time i ran across busy traffic was when my schoolbook bag fell off the back of my bicycle when going to school... at least 15 years ago. It was clear daylight, it was a single lane road, the bag had a grip handle and i knew the weight of the bag, enough to take a run over the road, grab the bag on the go and make it back across.
No way i'd try that with something as heavy as a truck tire when you dont know its weight, if its heavier than you think, you have already lost the second that can be fatal, before you decide to look over your shoulder and jump aside...
But yes, lately there was a dead cat on the road, i stopped, took a piece of paper left from the McDonalds and used that to toss the cat over into a corn stubble field.
Where i commute everyday, there is collisions every week because the road is too busy. 2 years ago i was the last car in a row of 5, one was parked on the hood of the other, because of hard braking both cars leaned over, the bump caused the one to stick its nose under the others behind. I had only a scratch. Cars driving 100kmh with only a single car length between them, is a risk of its own. NO WAY i'd risk my life to save somebodies paint job by picking up some trash from that busy road.... They have full time camera supervision on that stretch of road, they can close down one lane with the overhead matrix signs and THEN send a man in a yellow pickup with man-high flashers on the back of it, to pick up the trash.
