Anybody here racing on the 7" Firestones? Called "Wrinkle Walls"? And, they certainly wrinkled on 4" wheels. After a couple of races tubless, they began to leak at the wrinkles. Leave tubes in them, they pinched holes in the tubes. Learned to carry an air tank. Air tanks weren't real common back then. I made one from an aluminum Freon tank like used for home AC units. Think 30lbs? Found painting inside the tires with latex wall paint slowed that down a lot. Still had to air them up at least once a day. Everything simpler today. Have not used tubes in a race car tire since.
