In braking, which tire contributes the majority of stopping power?

In braking, which tire contributes the majority of stopping power?

• A. The rear tire.
• B. Both tires equally.
• C. The engine braking.
• D. The front tire.

Answer: (D)

When braking, most of the stopping power comes from the front tire. As you brake, weight shifts forward onto the front wheel, increasing the load there. That extra load lets the front tire generate more friction against the road before it starts to slide, giving greater deceleration. The rear tire loses weight during braking, so it has less grip and contributes less to slowing you down. Engine braking can help slow you down, especially with downshifts, but it relies on the engine’s resistance rather than road-friction, so its effect is smaller than what the front tire can provide. So, the front tire delivers the majority of stopping power.
