Improper tire pressure may cause

• A. Braking noise
• B. Improved fuel economy
• C. Limited traction
• D. Poor handling

Answer: (D)

Tire pressure shapes the tire’s contact patch and how the tire deforms under load. When pressure isn’t correct, the tire doesn’t sit on the road the way it should, which changes how the vehicle responds to steering, braking, and cornering. Underinflated tires flex more in the sidewalls, making steering feel heavier and the response slower, while overinflated tires become stiffer with a smaller contact patch, reducing grip and making handling feel less predictable. In either case, the vehicle’s stability and control during maneuvers are compromised, so handling is the most direct and noticeable issue.
