Hi everyone, how do we know the tire is not good? My current tire keep drags me to the left. After perform alignment, within 1 week the dragging effect comes back.

Tire shop sifu helps to diagnose the tire, he claimed the drag effect is come from the tire. He also placed the tire on the balancing machine, spin it and show me the tire was uneven of the surface.

Then he said no matter how many alignment you do, the drag effect will also come back. Need advice pls..
