Pay your money and take your chances.

Bicycle tire manufacturers generally offer a variety of models with varying degrees of flat protection. Riders make their tire selection, at least in part, on the degree of risk they are willing to tolerate. As a general rule more flat protection = more rolling resistance and a harsher ride so choose wisely.

FWIW, I've gone decades without ever completely wearing down a bicycle tire tread. I almost always cut a sidewall before the tread wears out. If I can still feel a bump after the tire has been repaired and re-inflated, I replace the tire.
