If you have a new tire on one side and a not new tire on the other side, that can cause problems similar to what you are describing. If you change one tire, you should change them both, in left and right aspects. What happens is if one tire has a larger diameter than the other they will cause problems such as, bad steering, pull to one side, vibrate and make noise. It is about the diameter of the tires, they need to be the same diameter. it is not critical front to back but essential left to right, and critical if it is on the drive axles. If it is a front wheel drive then the two front tires need to be the same diameter, if it is a rear wheel drive vehicle then the back two tires need to be the same diameter. In the front wheel drive vehicle you have the left and right drive shafts and the transaxle where the drive shafts attach to the gearbox. In a rear wheel drive vehicle you have the drive axle with the yoke in the middle, inside the yoke are the spider gears, those are what transfers the power coming through the drive shaft to the wheels. One question you can ask yourself, did the car do this before the tire was changed? If the answer is no, then that is a good place to start, if the answer is yes, then you will have to keep looking. Hope this helps you out.
