Steering and Suspension Chapter 37 Test

Technician A says that if the tire pressure inflation specifications on the driver's door are missing or painted over, you should check the tire pressure specification on the tire sidewall and inflate the tire to this pressure. Technician B says that is a potentially dangerous mistake since the specification listed on the tire sidewall is the maximum tire pressure the tire should contain usually after it has been operation and has heated up. Who is correct?

• Technician A

• Technician B

• Both Technician A and Technician B

• Neither Technician A nor Technician B

All of the following problems or conditions may be caused by improper wheel balance, EXCEPT:

• uncomfortable vibration.

• uneven tire wear.

• premature wear of brake pads.

• premature wear of suspension components.

Technician A says when checking a tire's air pressure, always refer to the tire sidewall information, and inflate the tire to that pressure. Technician B says when checking air pressures, compare them to the specifications on the tire placard usually located on the driver's door, door pillar, or glove compartment lid. Who is correct?

• Technician A

• Technician B

• Both Technician A and Technician B

• Neither Technician A nor Technician B

The wear patterns on a tire correlate with damage to particular vehicle components.

• True

• False

The cold inflation pressure of a tire is determined based on the:

• type of transmission in the vehicle.

• type of gas in the tire.

• vehicle's design load limit.

• engine capacity of the vehicle.

Tires and wheels must be balanced statically and dynamically.

• True

• False

Imbalance occurs when the wheel or tire is not concentric or when the tire's sidewall has uneven stiffness.

• Rotation

• Dynamic force

• Static force

• Road force

Which of the following is a clear indicator that the tire is at the end of its legal life?

• Out-of-balance conditions

• Tread depth above the level of built-in wear indicators

• Low tire pressure

• Tread depth below the level of built-in wear indicators

Over inflation of a tire causes excessive wear on the outer edges of the tread.

• True

• False

Feathering is most commonly a result of the tires set with excessive toe-in or toe-out.

• Groove

• Friction

• Feathering

• Balding
