It’s the threads of the tire casing like those below. It looks like you use talc.


It also looks like your tire is a 60 thread per inch (TPI) tire. Low thread count tires can be a problem if one of the threads breaks. The messed up portion of the tire above looks like this from the outside.




The tire had a definite snake belly to it.
