    Hello my name is sharon and i have a 2007 buick lacross when im driving its a vibration in the front i change my tires out and purchase new tires


    if the vibration is direct proportional with the speed, and is not dependent with braking, could be the wheels. Even if the tires are new, and rims are not bended, every time you change a tyre, that wheel must be echilibrated with a special machine in the service you are doing the tyre change.
    If these operation was made, go to your local service. Don't underestimate the situation.

    Cheers.
