When the front tire goes flat, the steering will feel:

• A. The bike will pull to one side
• B. The brakes will fail
• C. The throttle will stick
• D. The steering will feel heavy

Answer: (D)

When the front tire goes flat, the steering will feel heavy because a flat tire deforms more as you turn, increasing rolling resistance and making it harder to steer the front wheel. The tire can’t roll smoothly, so more force is needed at the handlebars to keep a straight path or to change direction. This heavier steering is the most noticeable change in handling with a flat front tire. The brakes aren’t inherently affected by a flat tire, and the throttle isn’t related to tire pressure, so they don’t explain the sensation you’d feel. Sometimes a very uneven flat might tug slightly to one side, but the defining experience is the heavy, harder-to-turn steering. If you ever notice that, ease off, steer gently, and slow to a stop to check the tire.
