Perhaps post a photo of where the brake and tires are contacting. It may be an adjustment issue.
The front most caliper arm hits the top of the tire on the tread. I'm not too worried about the inconvenience of tire changes, the larger concern is if the cable broke or disconnected while in motion, the calipers would open up and engage the tire. The best outcome would be shredding the tire and the worst would be head over heels. Having said that, in 12k miles of riding, I have never had a brake cable failure.
