Potholes and rough roads take a big toll on vehicles. Especially the steering and suspension components. Hitting curbs, railroad tracks, or speed bumps can all cause damage. Potholes form when moisture seeps through small holes and cracks in the road surface. As temperatures rise and fall, the moisture expands and contracts due to thawing and freezing. This breaks up the pavement and, combined with the weight of passing cars, eventually chunks out, creating in a pothole.
There are some tips to help reduce the damage a pothole might cause. The tire is the most important cushion between a car and a pothole. Make sure tires have enough tread and are properly inflated by checking the doorjamb or owner’s manual, not the psi listed on the tire.
