Alignment
As the your car components wear overtime, the wheels on the car doesn't stay centered.
You can tell this generally by having the steering wheel drift in either the loft or right direction. Most likely error is due to front wheel "toe in/out". This will cause uneven wear on the outer edge of the tire (or inner if toe'd out). Or if you run on a flatter tire for awhile, inproper wear.
To fix this issue, you would have to measure the angle offset through a string (diy) or lasers.
