Rotten, old tires suck to ride on. Tires don’t last forever, even sitting unused. If you are going to ride it, there are options on new tires that will get you there and back.
I gave this bike to a neighbor kid, but, like a lost dog, it came back to me, a couple of weeks later, after an adult in his world found him an old 10 speed. But, the Colson has good rubber on it, wasn’t worried about the kid riding it the way I gave it to him.
Consider some new rubber.
