You can see from the photos that the original tubes were bent as well. These are handmade cars (made one at a time) and all had parts "adjusted" to fit when new...and anytime you replace a part, you have to realize that there maybe some trimming, slight ending, etc.. Since every car is just a little different, one must expect to make "adjustments". That is why wider tires fit just fine on one car and rub on another. Old pros just automatically do this. The rest of us learn as we go.
