Hot Rods Tear in Radir slick, fixable?

Only one is damaged and they are not worn out, plenty of rubber left. I’m really not sure what tore it, nothing was left in the tire. I’m thinking it was due to the high heat here in Az, but really don’t know.

 

Amazed at the amount of “trolls” on here. In my world no question is stupid, and I surely wouldn’t criticize someone instead of trying to help them or answer their question. Opinions are one thing, I definitely have my own and they aren’t always all positive, but, are you helping or hurting? Or just being an internet dick because it’s easy? Thanks to all who truly answered and/or tried to help. You get what you give in the end.
