They're the bane of modern interstates and countryside roads alike: Potholes cost American drivers nearly $6.5 billion dollars in flat tires, blown shocks, and cracked rims in 2013, according to AAA. Save your car this beating by learning to recognize the early warning signs of developing potholes and how to get them fixed before they turn into sinkholes.
