I noticed my tires (stock) are going flat. The foam wont withstand any pressure its almost like i'm driving on my rims. Then i opened up my tires and found that my tire foam was scredded to dust peaces. Is the foam supposed to be glues to the tire or something? i'm geting some new tires anyways but the foam is completely shredded almost as if the foam was spinning against the tire. Has anyone else has this problem?
