just a reminder, that there are some people on the road who aren't concerned about their safety enough to be cautious about their tires... or they can't afford to get tires, even used ones.

from the clutter in the back window, I think this truck owner is living in the truck... and that front tire is blessed by great design and strong materials, as the outer layer of rubber and outermost layer of wires is already worn through.

Be careful out there, because you may need to prevent getting into a collision with someone else that causes a crash through easily prevented problems, like a front tire blow out.
