Cracks on inside of tyre

Hi Guys,
Had this Tyre removed to have the wheel refurbished, looked inside for any damage and spotted a crack all the way round inside. The tyre is 255/30r21 btw.





Guess its new tyre time? Could this have been caused by the tyre removal?

Thanks, looks like was running under inflated at some point. Correct load rating.
