Dunno, but tire shake on Alky cars always indicated that the wheel speed wasn't keeping up with the wrinkle wall tire . . Once you let the wrinkle move below about 7 o'clock, either the tire will stand up or shake . . either way . . You lose, because your 60' time went into "Suck" mode . .
Way long time ago, a fella named Force (back in Diamond Bar) told me how to launch an Alky Funny Car using the wheelie bars . . And he told me about that damned wrinkle . . I have yet to see it disproved, and I've argued with it myself, several times . . Ole John is still right . .
Used to be, with the old stiff sidewalls, you could never be "Over tired" . . Today, with the selection of cams, converters and tires, nuthin to it . . Hell, with the old stiff sidewall tires, we used to use a narrower wheel and use the tire for the "overdrive" . . If the wheel was narrower than the tread, it'd stand up like a bicycle tire in the lights . . Damned things would grow to about 15% outside the max measureable tire diameter. Go back and look at the old photos of the Fuel Dragsters from 1973 to about '76. Look at Garlits doing a burnout or in the lights. He used a 10" wheel with a 12"+ tire . . Heh, heh, don't even try that today!
I don't know that our friend is over tired or under tired . . I'm just guessing. After all, how much is my house worth over the phone? But so far both of us have been in the ball park on several issues. I guess we'll have to let him sort it out . . But thanks, you are pretty damned knowledgable about our pasttime . . I appreciate it . .
