Mike very interesting about the wide whitewall vinyls there. I'm wondering if its a climate issue as well? Possibly maybe with the wide whitewalls themselves. I have a set of tires with the Pegasus thin white walls on them that are about 15 years old and they're still stuck on like the day I placed them on. I also have another set the same age and builds, that are still on, minus some deformation on the back white walls.
I used that set for a few test fits on some bodies, I had pushed them down into some fenders that stretched the white walls out on one spot. They're still stuck on to this day though. I live in California I don't know if its a climate issue as to why I have never experienced that issue. Also I'm wondering if maybe the wide whitewalls may have too much surface area over time it does curl up like that? One thing I did do before I put the vinyls on, was I washed the tires and scrubbed them with some dish washing soap first.
I think I'm going to try a set of the wides myself and see how they do over some years time. I have a set of the wides from Pegasus I haven't used yet. Thanks for sharing the picture Mike, I never seen that happen before, always heard of it.
