Why are my front tires scalloped?

Why do tires wear out on outside of tires?
Front tires wearing on the outside edge is usually a result of aging coil springs . As they lose height, so does the vehicle, causing the whole suspension to misalign, especially in camber. If the leaf springs are also sagging or wearing out, they cause caster misalignment, which may worsen the situation.
