M.A.D. Break-A-Way Tire
The tire is constructed so that it can stay outside and will not lose its shape. The color is injected into the tire so you never have to use tape on the tire and it will not lose its color. The magnet is adjustable so you can set how much it takes to open the tire. Does not open if your dog brushes the inside. The tire is available at 21″ & 24″ for USDAA.
