Its difficult from the photos to tell what you are trying to show. Has the rim split? Dont ever put a tube into a tubeless tyre. Your life is worth a lot more than the cost of a replacement rim or a professional repair. More photos may be helpfull
OK
so just out of interest, what's the difference between a tubed tyre and a tubless one when the almighty deflate at speed happens.
why would it make such a difference?
Generally not a problem running a tube in a tubeless tyre.
Heat is the main difference, and speed rating should be lowered. Not a fan of running the wrong size tube, but it can be done in an emergency.
