When I was working as a mechanic, we used to cut up tyres too worn to be used for anything with a tiny little box-cutter, you know the kind with the little trapezoidal blade? Trick is, you've gotta get the tip of your knife into the sidewall, and then cut with the grain of the rubber. Also don't cut inflated bus or truck tyres, they'll fucking kill you. And I'm not exaggerating, they'll fucking kill you dead.
Also, Netflix got rid of Stargate Atlantis, at least, in Australia. Which wouldn't normally be notable, but they did it right when I was in the middle of an episode, it hitched, displayed the error dialog, and then completely vanished from their catalog. Now I need to find some other dodgy mid-level sci-fi to watch while I'm working.
