So Coker has a few tubes to choose from. In an effort to get all the right bits at the same time, can anyone tell me if one of the tubes are better for stock wheels than the others? Also, are the 'flaps' really necessary? AND finally, is a 'Non-DOT Approved' tire an issue? These are going on a 3600 in Ontario.

Thanks!
