Default Re: Radial tires on old rims

Here is my take on the whole issue. The rims were made to take the load of the car at full traction of the tire. They should be plenty strong enough whether forces are later horizontal or vertical. I've heard people swear up and down about hubcaps falling of the rims with radials. I just cannot picture a rim flexing that much. I'll believe your stories but I'm unconvinced that is the root of the problem. A tube is just a bladder to hold air and I cannot see how it helps hold a tire to the rim. It can make it easier to seat the bead but that's it. Any leaks in the tube will escape through the valve hole in the rim. Other that wire wheels I see no use for them and wires can be sealed up pretty well if that's your goal.
