It sounds like you have some loose lugnuts. Luckily, Your car should have all the tools to fix this right next to the spare tire. To see for sure, jack up that side of the car, following the instructions on stickers near the spare tire or in the owners manual. You will need to jack up that corner of the car, and use the lugnut wrench to tighten those nuts as tight as you can get them with that little thing. If this was the problem, you need to then drive the car to the nearest tire repair store and have them tighten those down for you. If you have a torque wrench, tighten them to 85 ft/lbs.
