I don't know if it's normal. But if you frame to frame the Force/Bernstein crash it looks like John's right side tire fail at the stripe... you see a big junk of something fly off and split into two pieces and that's when all hell broke loose.

It appeared to me that the top-fuel cars had lots of tire chunking in the
shutdown area. You could actually see the chunks flying off of a number of cars.
(fuller and Dixon).

Could his tire of been chunking causing the chain reaction that occurred to Fource ?
