How Temperature Can Affect Your Tyre Pressure

How Temperature Can Affect Your Tyre

Tyre pressure changes are often not visible. But when you CAN actually see it, it would have already been pretty significant. Tyre pressure change can affect any vehicle, thus it can be especially surprising for car owners who “do not drive often”. However, your tyre have many invisible enemies; temperature is one of them. In this article, we address how temperature can affect your tyre pressure. But before that let’s discuss the science of it:

Why Temperature Can Affect Your Tyre’s Pressure

This is probably something you already know, but we’ll do a refresher. All matter expands when heated and contracts when it cools down. Your tyre is made up many things that causes it to contract and expand. This fluctuation of tyre material affects the air pressure inside, thus affecting fuel consumption, tyre life, and more importantly, safety.

Find it hard to believe? Here is a little perspective from people who drive for a living. In summary, formula race drivers consider tyre temperature an integral factor in performance. Before every race, they would do laps to warm up their tyres for optimised grip. You may not be a race driver, but this is a great example of how temperature relates to tyre optimisation.

Now that we got that out of the way, let us talk about how the temperature of the tyre gets its changes in the first place.

Heat From Driving

Rub your hands together and you feel them getting warm. The same happens with your tyres every time you drive. Friction between your tyre and rough surface of the road creates great traction, but it also create great heat.

Hence, under-inflated tyres generates more friction and cause heat. Not only that, your running engine is also contributing to the effects of heat, especially in your front tires.

But driving is not the only culprit for temperature fluctuations to your tyre.

Heat from Weather

Experts have predicted that Singapore will be experiencing significant weather changes by the next few decades. In fact, we already felt it; 2016 is the hottest year on record. With the historically drier season coming in February, temperatures are about to soar again.

Imagine how that can affect your car’s tyres. Even if you were to, say, go on a long vacation and not drive your car for a week, fluctuating temperatures in the day and night still contributes to your tyres’s temperature, especially if your car is being parked in open parking lots, which are common in older home estates.

Other Factors About Tyre Temperature

Here’s something you probably don’t realise: Heat can be absorbed and diffused rather well by dark coloured material. Unless for some reason you can get white tyres, your car practically puts on a black tyre like a uniform. Hence, your car naturally attracts and dissipates heat quite quickly, causing significant fluctuations of temperature that can affect the tyre pressure.

Do not also forget that our roads are mostly dark tar-based material that gets hot really quickly in warm weather. This heat can also get transferred to your tires.


We hope that this article gives you some valuable insight into how temperature and tyre pressure.
