I have a Pontiac Bonneville 1993. It has a wine in the front end and is wearing tires out on the outside
You need to have the front end checked.
Excessive toe-in or camber. Have the car aligned and check all the steering components for wear. The noise/vibration may be bad bearings, which can also cause tire wear in extreme cases.
