yboy82 4/9/2012Prolonged driving on overloaded/underinflated tires or a road hazard are the most likely causes, if the sidewall separation/bubble appears after six months of on-vehicle service. However it may take weeks or months after an impact for a separation/bubble to appear as the damaged or bruised area continues to weaken. I would suggest that before you buy he vehicle the suspension system should be check by your friend/trusted mechanic. Because if the past owner hit a lot of potholes like the dealer said the suspension of the vehicle should be affected.
