Do I need to change my Tyre Pressure if I am carrying more passengers?

Maintaining the right tyre pressure for your vehicle is a paramount element of driving safety. 

Not only does this mean knowing what tyre pressure your vehicle requires (and regularly checking the status of your tyre pressure), but also understanding how the optimum tyre pressure changes in different driving conditions. 

Below, we’ve shared a guide to tyre pressure requirements if you’re carrying more passengers. Keep reading to find out why, and by how, you need to adjust your tyre pressure when carrying heavier loads and/or multiple passengers.

 

Why is it important to maintain correct tyre pressure?

Maintaining the correct tyre pressure for your vehicle is critical. 

This is due to a number of key factors:

• Vehicle safety – Under-inflated tyres can increase the risk of overheating, blowouts, and compromised steering and handling. Equally, over-inflated tyres can also significantly impact steering, handling, braking and cornering. 
• Tyre and vehicle lifespan – Incorrect pressure can cause the tyres to wear at an uneven rate, significantly compromising their lifespan. 
• Fuel efficiency – Low tyre pressure requires the vehicle to consume more fuel to achieve the same output. 
• Comfort – Incorrectly inflated tyres can also affect the comfort and ride of your vehicle. 

 

Changing tyre pressure when carrying heavier loads

When your vehicle is carrying more passengers or a heavier weight (e.g. if you’ve added luggage), then this can increase the strain placed on your tyres. 

As a result, it is recommended that you adjust the pressure of your tyres, so that you don’t risk any of the above hazards developing. 

To find out how much to adjust your tyre pressure, we recommend first checking the driver’s manual to see whether the manufacturer has any recommendations.

Most vehicle manufacturers provide two sets tyre pressure recommendations:

1. Normal driving conditions 
2. Fully loaded conditions (either when you’re carrying multiple passengers, or heavy loads)

You can usually find these recommendations either in the owner’s manual, or displayed inside the frame of the driver’s door.

For most vehicles, the pressure increase required for fully loaded conditions is around 3–6 psi higher than normal driving conditions. But, you should always check the manufacturer’s recommendations, to ensure you are maintaining safe driving standards.

When checking or altering your tyre pressure, don’t forget to check your spare tyre, while you’re at it. That way, if you ever encounter any issues, your spare tyre is ready and safe to use.
