Yeah, tires are amazing.
We were shooting at stuff on the ground, in front of an old tire, with .44 mag revolvers.
The bullets were skipping off the ground and hitting the tires, like they were supposed to.
But they didn't penetrate, just got stuck in the tread.
At the local club, they used to use stacks of tires for side berms, to divide the range into separate ones.
They worked good for many years like that.
