Question 7989

When tire pressure is higher than recommended by the manufacturer...

  1. the contact area with the roadway decreases and traction is lost.
  2. roadway irregularities are absorbed better.
  3. the tires wear less but heat up more.
Show answer and explanation

Correct answer: the contact area with the roadway decreases and traction is lost.

With more air than recommended, less of the tire touches the ground and it grips less well. It doesn't last longer either, because it wears quickly in the center, and it absorbs bumps less effectively, so the car vibrates and bounces more. In the image, the pressure gauge needle is in the red zone.
