Understanding Radial Tyres Quiz

What is the primary structural difference between radial tyres and bias ply tyres?

• Radial tyres have layers of fabric running at a 45-degree angle to the direction of travel.

• Radial tyres have layers of fabric running perpendicular to the direction of travel.

• Radial tyres have no fabric layers.

• Radial tyres have layers of fabric running parallel to the direction of travel.

Which of the following is an advantage of radial tyres over bias ply tyres?

• Radial tyres provide a smoother ride.

• Radial tyres are cheaper to manufacture.

• Radial tyres have a shorter lifespan.

• Radial tyres are more prone to punctures.

What is a common disadvantage of radial tyres?

• They have a higher rolling resistance.

• They are more expensive to produce.

• They provide less traction on wet surfaces.

• They wear out more quickly.

How do radial tyres compare to bias ply tyres in terms of fuel efficiency?

• Radial tyres are less fuel-efficient.

• Radial tyres are more fuel-efficient.

• Both have the same fuel efficiency.

• Fuel efficiency depends on the vehicle, not the tyre type.

Which of the following is a recommended tyre maintenance practice?

• Rotating tyres every 10,000 miles.

• Checking tyre pressure once a year.

• Balancing tyres every 5,000 miles.

• Inspecting tyres for wear and damage regularly.

What is the environmental impact of improperly disposed tyres?

• They decompose quickly and enrich the soil.

• They release harmful chemicals into the environment.

• They have no significant environmental impact.

• They can be used as a natural fertiliser.

What is the typical construction material used in the belts of radial tyres?

• Nylon

• Steel

• Cotton

• Polyester

Which of the following is NOT an advantage of radial tyres?

• Better heat dissipation

• Improved fuel efficiency

• Lower initial cost

• Longer tread life

How often should tyre pressure be checked to ensure optimal performance?

• Once a month

• Once a year

• Every 10,000 miles

• Every 5,000 miles

What is one of the main reasons radial tyres provide better handling than bias ply tyres?

• Radial tyres have a stiffer sidewall.

• Radial tyres are lighter.

• Radial tyres have a softer tread.

• Radial tyres have a higher rolling resistance.
