Mom trying to start new job with completely bald tire

We have a single mom trying to start a new job in need of one tire.  The current tire has steel belts showing through!  The tire size is hard to get and not cheap ($238.90 per tire company).  If she could afford to get different size tires and rims she would, but replacing the one tire is the cheapest option.  Donations can be made through the link on our website but please respond to this post to give us a heads up.  (Funds collected will be given directly to the tire company: Rimtyme 4615 Dixie Hwy, Fairfield OH 45014)
