Should I increase tyre pressure for a heavy load?

However, there are certain circumstances that call for tyres to be inflated to levels that are outside of those generally recommended pressure levels.

Heavy load tyre pressure 101

Tyre pressure is measured in pounds per square inch (PSI) and every vehicle has its own recommended levels, which should be adhered to when carrying a standard load. When carrying a heavy load, it is usually advisable to increase the pressure in your tyres to ensure that the full weight of your vehicle is properly supported.

Your tyres should only be inflated to the maximum PSI when your vehicle is full, that is when there is a person in every seat and the boot is full. If your vehicle is half full, then it is a good idea to increase the pressure to a PSI that is halfway between the regular and maximum recommended levels.

Do tyres with higher pressure levels feel different?

When driving with over-inflated tyres and a normal load, you will find that you don't have as much control because only the central part of the tyre will make contact with the surface of the road. This can result in a jarring driving experience, with reduced grip, braking and poor steering performance.

As well as providing a generally uncomfortable ride, over-inflated tyres won't absorb impacts from obstacles such as potholes, which will transfer through your vehicle's suspension and could cause a range of issues.

What do I need to know about checking tyre pressure?

• Tyre pressure should always be checked when they are cold.

• Your vehicle handbook will set out the recommended PSI levels.

• Tyre pressure should be checked frequently, ideally once per month.

• Don't forget to check your spare tyre too.

Maintaining the correct PSI

It is important to remember to reduce the pressure levels again when you will no longer be carrying a heavy load. This is because over-inflated tyres have less contact with the road, which reduces grip and will lead to additional wear across the central part of your tyres that can and should be avoided.

You may find it helpful to check your PSI every time you refuel your vehicle, as this will ensure it becomes part of your maintenance routine.
