I quite running tubes in the early '70s. Got tired of pinching the tubes and having tires go flat between rounds. The old bias tires would sometimes pinch the tube at the launch. Carroll Caudle and I both had that happen about a week apart. We both ruined tires by the time we got our cars stopped. He was the first (between the two of us) to try it tubeless. His car also picked up ET & MPH tubeless. I changed over and picked up also. Those old Firestones would just about go flat during the week. My MT & Goodyear radials hold air just fine. Seldom loose any at all between races. The Hoosier radials I ran before didn't leak either. As much air as I run in my radials, I don't even run screws.

Had one of those guys that always seem to have a beer in their hand walk by once (had Hoosiers then) and tell me "You had better put screws in your wheels! Your tires are slipping on the wheels!" I didn't walk back to check, but asked him "Is the letter i in Hoosier lined up with the valve stem?" He looked and said "Yes!" I said "Dang! Must slip back to the same place every time!" Not sure he even got it. :-)
