What could cause my car to turn left on highway speed.

I mean if I take my hands off the steering wheel it will turn left after 2 seconds so I have to keep the steering wheel a little on the right the whole time.

I bought the car like this and I didn't noticed something on the tires (they are pretty new)

Do I need alignment? Something else?

I have it on my other gp too

If its alignment. Can I do it myself or better pay 90$ to the shop?
