What is the purpose of body plies in a tire?

• To provide additional traction

• To form the carcass or body of the tire

• To support the tire pressure

• To prevent the tire from wear

What is a characteristic of a compact/space saver spare tire?

• It is larger than the normal tire

• It has a thinner tread and sidewall

• It uses less air pressure than normal tires

• It is designed for off-road vehicles only

What does a directional tire improve?

• Comfort

• Vehicle handling and minimizes hydroplaning

• Tire lifespan

• Fuel efficiency

What information does the DOT serial number on a tire provide?

• The tire's speed rating

• Manufacturer, plant location, construction, and date of manufacture

• The tire's traction ability

• The tire's rolling resistance

A drop-center wheel is designed for:

• Reducing the weight of the vehicle

• Improving fuel efficiency

• Facilitating easier tire mounting and removal

• Enhancing the vehicle's aerodynamics

What is the function of a dust cap on a vehicle's axle or spindle?

• To enhance wheel aesthetics

• To prevent dirt from entering and grease from escaping

• To reduce rolling resistance

• To increase the tire pressure

What is the role of the hub in a wheel assembly?

• To provide traction for the tire

• To hold the wheel in place on the axle

• To reduce friction

• To store the spare tire

What does the maximum inflation pressure marking on a tire indicate?

• The maximum amount of weight the tire can carry

• The highest air pressure that should be pumped into the tire

• The recommended speed limit for the tire

• The amount of friction the tire generates

What is the function of a wheel bearing?

• To balance the tire

• To reduce friction and support the wheel's rotation

What does the tread wear rating on a tire measure?

• The tire's ability to resist heat buildup

• The tire's resistance to wear on a scale from 100 to 500

• The tire's maximum inflation pressure

• The maximum allowable speed of the tire
