Truck tires already worn out?

Hi,
I don't really know much about truck tires, so I'm asking this silly question and hope you can assess it. For a car tire, I would have said it's worn out and needs to be replaced. Do I see this the same way for a truck tire, or do they still have a good tread for maybe the next 15k kilometers? Thank you very much :-)

Thanks, regards

well that already looks really bad

Worn out (tread worn) is not the problem here, they are simply damaged.

Dents, as far as I know, come from impact fractures, meaning someone shot over it somewhere and thereby damaged the carcass. No idea about the tread. Measure and then google regulations and recommendations. The little "stone" could probably be removed as well, or is that a load-bearing component ;-)

The bumps make me feel quite different...

And the tread is already worn through. The markings for minimum depth are partially already worn off.
They're just done for.

thanks for the opinions, the tires are not mine, but the dents were probably caused at my construction site and the owner would like new tires at my expense.... but since, as you yourselves say, the tires are worn out, I don't see it that way.... I see it the same way regarding the minimum tread depth, I was just not sure if it is interpreted differently for trucks, since I actually have no idea about tires. they should roll and have enough tread, I don't have more opinion about tires :) but sorry, I should have explained that in the first post - it was misleading :)
