The above comment seems to be making a distinction that braking force comes from the tires or the brakes. That is not how it works.

The brakes provide friction to resist the spinning of the wheel, but of course only to the point that the tire can provide grip (friction) against the road surface.

Picture trying to brake with slick tires on wet ice. Nearly zero tire grip equals nearly zero braking force. Doesn't matter what kind of brake components are on the car. No grip = no grip.

If you want to be able to stop quickly to avoid accidents you need to maximize grip a the tire-road contact patch and you need to have a braking system powerful enough to fully take advantage of that grip.

Every car sold for decades now already has the latter (unless something is broken, obviously), so the variable you need to control is tire grip.

Thus: Buy the grippiest tires you can afford to run (if you want optimal braking to avoid accidents, that is).
