Why does my car shake at slow speeds?

By definition, a wheel runout refers to any component of a wheel or tire assembly that is not perfectly round. It is a dynamic imbalance problem that results in wobbling at slow speeds and severe rattling at high speeds. A flawed tire-wheel assembly may include tires with shifted or broken belts.
