Tires should never be used for horse feeders. Always examine your methods used to care for horses!  One of the most neglected areas is how horses are fed.  Horses have a tendency to hurt themselves on just about anything. Using tires for hay feeders has always been a dangerous situation.  Horses have been known to get stuck in them and suffocate.  Also, overtime the steel belts can become exposed leading to sharp ends that horses can cut themselves on.  Always feed your horse from a feeder meant for horses.  At Pro Panel we understand horses.  Our 3-in-1 Horse Feeders feed your horse the way nature intended.
