Super Tricks at the track

Back in the mid 1970s, I was visiting my go to car builder guy. He was doing some maintenance on a customer's 68 Camaro drag car. He asked me to hand him a front SuperTrick with a front runner drag tire on it. I put my hand through the center hole and gave it a yank off the floor. I almost tossed it over my head. I never would have guessed how light it was.
