Wondering when it’s okay to pump your tyres above the normal value? This guide explains when increasing tyre pressure can actually help — especially for heavier loads, long journeys, or specific driving conditions. Learn how to balance safety, comfort, and performance without risking overinflation.
Most vehicle owners will be familiar with the pumps at garages and petrol stations, which are dedicated to adding and removing air from car tyres. Often operated by tapping your car or inserting payment in coins, the screen invites drivers to set the ideal pressure for their tyres and then fix the valve to their tyres one at a time – adding or removing air until the pressure matches that set on the screen.
Understanding tyre pressure is important for a number of reasons. The right tyre pressure extends the lifespan of the tyres and gives the driver optimum control over the vehicle. Meanwhile, underinflation can cause structural damage to the tyre and overinflation can increase the risk of the tyre blowing on a rough or uneven road.
Having said that, there are instances where increasing tyre pressure above the normal value is beneficial and even recommended.
Occasions When Adding More Pressure is Beneficial
Contrary to popular belief, adding some extra air to your tyres is recommended when carrying a heavier than normal load. This is because the pressure and weight on the tyres is high, with the extra pressure helping to keep the tyres inflated and moving efficiently rather than sluggishly.
Most vehicle handbooks will contain information about the optimal tyre pressure for the vehicle, with different options depending on the number of passengers and the load being carried. It’s important to check this and assess the pressure of tyres before any long journey.
How to Avoid Overinflation
Overinflation can be just as dangerous as underinflation, as it not only increases the chance of a pothole or bump in the road causing tyre damage, but it also impacts driver control over the vehicle.
When tyres are overinflated, the sides of the rubber are elevated above the road surface which reduces the contact point between road and vehicle. This can lead to a loss of control particularly on wet or icy surfaces, and when driving at speed.
