Wheel rub on carbon

So for the forth time my large heavy frame has proven unsuitable to the light subtle design of a road bike and it's components.

Somehow riding up an incline and giving it some I managed to bust a spoke.

I am curious if anyone is aware what would be fatally damaged first, the carbon chain stay or the tyre?

There is quite a mark on the tyre and was a bit of a burnt rubber smell but not to worry about that, is it possible to eat through the carbon though?

Fatally is a big word, and either way it would take some time.

I always suggest some ballistic protection inside the chain stays and fork blades. It could be as simple as some duck, fiberglass or metal muffler tape. I don't ride CF frames But if I did, I'd find something that's fairly abrasion resistant, and might go so far as fashioning a thin piece of stainless shim stock for the job.

Tires are sacrificial, so I wouldn't sweat it unless there was a long ride home. In any case, on a metal frame, it'll always the the tire that loses. On CF it could be a toss up, with a critical factor being how much grit the tire picks up to use against the frame.
