Misha,
Eweedhome is right. Unless you buy your NOS tubes from a respected seller you are in for trouble, unless you buy a tube tester ( to be found on ebay ) have it checked and calibrated and test every tube you intend to use for rolling. A popping tube belongs out unless you want to risk damage to your gear.
