question

[Guest Markus355]

building a 66 GTO into a gasser/street machine, now i was planning on taking a pair of the solid pie crust slicks from the amt double dragster kit and turning a pair of grooves in themn on the lathe to make a set of cheater slicks.

my question is, when did wrinkle wall type slicks become common place?

I'd say around the Gasser Era(1955-1965).

I think they'd look cool on a GTO.

I have researched this issue. 1965 was the year that smooth sidewall slicks came out and people ran both styles that year. 1966 saw less people using the pie-crust style but they were still many being used. 1967 saw virtually nobody who was up to date and competitive still running them. The smooth sidewalls weren't "wrinkly" right away. It took until 68-70 before the wrinkling benefits were known about and utilized.

Andy is right. I ran a '57 Chevy in '67-8-9 and I had a pair of pie crust slicks on it with chrome steel wheels. I sold the car in '70 and saw it 15 years later and it still had the slicks on it. Don't think they were new. It was still being drag raced locally in bracket racing. Hope that helps. Patrick M

Yup, Andy pretty much hit it on the head. It's not like they dropped off the face of the planet beginning Jan.1, 1966 as you could still see them being used by the top teams early on during the season. However, by Jan., 1967, they were considered obsolete compared to the new tires and rubber compounds and the switch was on for the new tires.
