Default Rubbing the tire on the road, is it really mathematically simple?

When a new set of tires get a few years old, they also get harder. They will sound like a bad rear end bearing. I had a new set of Kumho tires on my old van, they started making a bad bearing noise after a few years. Those tires don't get much traction on wet streets either. I bought some new Cooper tires and that noise stopped.
