Ok..i figured whats wrong..I started messing around with the tire and I noticed that the valve thing where you put the air in was hissing. So I kinda bend it and sure enough air just starts coming out. So I was wondering is this problem fixable because it has nothing to do with the tires so how can a place fix this. I dont think they can seal it because there is no hole its just loose at the end of it and thats how the air escapes. Are those things replacable??
