Question 5261

A tire with incorrect inflation pressure...

  1. wears unevenly and has a greater risk of a blowout.
  2. usually uses less fuel.
  3. wears less and has a lower risk of a blowout.
Show answer and explanation

Correct answer: wears unevenly and has a greater risk of a blowout.

With too little air, the tire wears more along the edges, heats up, and can blow out. With too much, it wears more in the center and is more easily damaged by impacts. In both cases, wear is uneven, and with too little air you also use more fuel, not less. In the image, the front tire is severely underinflated.
