Difficulty: EasyLoading the Vehicle Safely

You are preparing to set off on a journey with your car carrying a full load of passengers and luggage. What adjustment should you make to your tyres before starting the trip?

  1. A
    Reduce tyre pressures to provide a larger contact area and a softer ride
  2. Increase tyre pressures to the recommended settings for carrying heavy loadsAnswer
  3. C
    Reduce the tyre tread depth to help the tyres grip more firmly on dry roads
  4. D
    Leave tyre pressures lower to counteract increased stopping distances

Answer

Increase tyre pressures to the recommended settings for carrying heavy loads.
When a vehicle is carrying a full load of passengers and luggage, the extra weight puts greater stress on the tyres. The vehicle handbook specifies higher tyre pressures for full loads to ensure optimal contact with the road surface, prevent the tyres from flexing and overheating, and maintain vehicle stability.

Step-by-Step Solution

1
Check the vehicle handbook or tyre placard for loading recommendations.
Identified the specific higher PSI/bar pressure settings required for a fully loaded vehicle.
Vehicle manufacturers specify distinct tyre inflation pressures for normal versus fully loaded conditions to preserve safety.
2
Inflate all tyres to the heavy-load specification while the tyres are cold.
Tyre pressures are correctly set for the additional weight of passengers and luggage.
Proper tyre inflation ensures correct contact with the road, prevents overheating, maintains steering responsiveness, and supports fuel economy.
