little help with a chevy metro? haha

Bad tire or CV joint.
Doesn't matter how many miles on them or how they look.
I would be more concerned about being upside down on the side of the road, since you said it's worse every time you drive it.
Tire separartion can happen very sudden and violently.

Although it could be just a balance problem getting worse because of the balance problem.

Take it to a tire shop and ask for a diagnostic test drive.
