Shaking at 40 mph

Q: Traveling around 40 mph my car begins to shake. What do you think is causing this problem?

A: Shaking can be caused by tires being out of balance, broken belts in a tire, or worn suspension components. Tires that are out of balance can cause vibrations at different speeds leading to unsafe driving. Take your car in to a tire service center to have your tires inspected and rebalanced.
