Inner Tubes for Radials?

[cas3]

Well, only slightly off track here, but the normal tubes made today are of such shit quality that some folks run the radial tubes in bias tires because they are of much better quality, and i believe made by real companies and not a shack in china. As far as being safe, most of us are old enough to remember that tubeless tires came out many years before the rims ever had that extra "safety" bump around the wheel. I believe that bump is only an aid to help get a tire to "air up" when mounting, and has nothing to do with keeping a tire on the rim if you have a flat at speed. I have no radials...yet, but i plan to. I know from an old brand x thing I switched to 15" radials in the 80's, drove like a whole different car
