It would be good if we could see pictures. But you can't post pictures until you have 10 posts. Some people post on another website and post a link to it. I don't know if you have that option. There can be so many situations where brake cables rub against tires.
On my fat bike, the front brake cable would rub on the tire when the front suspension went down. It did run inside the forks. I rerouted it to run outside the forks.
