Rear tires wearing out on the inside of tires. on 2004 Mazda Mazda3

My rear tires are not wearing out evenly, wear out on inside of tire.

Asked by for the 2004 Mazda Mazda3
The alignment is causing the uneven wear. If the tires are splayed outwards(negative toe value), they will scrub the inner edges as you drive. This will also happen if the vehicle has been lowered, causing the tires to tilt inwards riding on the inner edge of the tire. I recommend replacing the tires and having an alignment performed.
