The letter and numbers G78-15 printed on a tire refer to ________________.

  1. load, width, and diameter.
  2. diameter and air pressure.
  3. cubic inch displacement.
  4. price code.

Answer(s): A

Explanation:

"G" indicates the load-carrying capacity of a tire. 78 is the aspect ratio, which is the relationship between the tire height and tire width. When a tire is marked 78, the height is 78 percent of the width. 15 indicates that the tire will fit a 15-inch rim.



"Tracking," in terms of front-end alignment, means that .

  1. each wheel travels independently of the other.
  2. the wheels follow well on ice or in snow.
  3. the front tires leave stronger tracks than the rear tires.
  4. the rear wheels follow the front wheels correctly.

Answer(s): D

Explanation:

Tracking is correct when both rear wheels are parallel to, and the same distance from, the vehicle centerline, which is an imaginary line drawn through the center of the vehicle. A bent frame or twisted body structure will cause improper tracking.



A car with worn-out shock absorbers _________________.

  1. cannot carry a heavy load.
  2. will bounce a lot on a rough road.
  3. sags very low to the ground.
  4. will have no traction on a wet road.

Answer(s): B

Explanation:

Shock absorbers control spring oscillation. Original equipment shocks that do not use air or spring assists are not designed to control vehicle height.

  1. pinion shaft
  2. countershaft
