The brakes *will* stop the plane at V1. Other than that, there may be

For you and Steve, please go back and read where I posted"

Many aircraft tire failures are due to overheated brakes, heating the
wheels to the point of causing the tires to blow out or burn, not from
heat generated by the tires themselves.

That was in reponse to a post that claimed the wheels would provide
sufficient heat sinking to cool the tires.

Yes, I saw that and agree that when airliner brakes are used excessively
they can cause tire blowouts. But again, the braking requirements and
capabilities and the heating of the tires of an airliner vs. a race car
couldn't be more different. To suggest that because airliner tire
failures due to the brakes generating too much heat mean that race cars
also can't dissapate their braking heat fast enough to prevent tire
problems is a non sequitur.

As an ATP and former airline captain I am very familiar with aircraft
braking limitations.

I'm surprised then to hear you say that thrust reversers provide little
braking at high speeds when in reality, they provide most of their
braking at high speeds and much less at low speeds. That's why, when an
airliner lands, they'll use the thrust reversers first, while the plane
is going fast. Then once it slows down sufficiently, they'll use more
of the brakes.
