Bent rim. If you rotate it to the rear it may eliminate problem. Have the wheels inspected and replace a bent one. Putting it on the rear will cause your rear axle bearings to wear out. Do not mount a bent wheel on your car, replace it.
If it is severely bent the side wall in that area may be damaged, but if it is just a curb hit, the tire should be fine mounted on another rim. If it is a steel rim, the tire can be taken off and the lip of the rim bent back into place and used.

You've hit and run over something with the car.
Probably not. It may be worth the five or six dollars to try.
Yes, I usually buy old cars and keep them a couple years. Every one has had a bent rim
You may have a bent rim or damaged the tire.
could be tires out of round,bent rim,out of balence wheel or wheel bearings. or it could be the u-joint is bad and it is off balancing your drive shaft
If the rim is bent, the rim needs replaced and is the problem.
I wouldn't say bad for your car however you may notice a wheel wobble when driving, if tis an alloy wheel get it checked incase the rim may have a hairline crack
