Hey guys, so i put my winter tires on the other day and everything seemed fine for my first trip out. Then later in the day i was getting a loud knocking noise that sped up as the car sped up (consistent with the rotation of the wheels) I can't see anything physically hitting anything and the knock sounds like im going to break something if i keep it up. The car is going in today for a new driver front ball joint, however this sounds like it's coming from the middle and i can almost feel it on the gas pedal. If i let go of the steering wheel it still drives fairly straight, but you can see the wheel twitch a bit everytime you hear the knock. I'm hoping the shop knows whats up and that it isn't too expensive, but does anyone here have an idea what this might be?? Thanks!

Sounds like a wheel is ready to fall off. You'd better park it real quick and check torque of all lugnuts. 80 ft/lbs. don't forget the star pattern
