This tire has the different construction of its double cavity. When the tire is broken, we usually think about replacing the spare tire. But it is a hard work. Considering the width of the spare tire is half of the normal one, we designed this double tire. When one cavity is pierced a hole and leaks, the other cavity is intact and the tire can keep the same height and continue working. Now it will not be a flat tire during our entire trip.
