Jun 27, 2024 · As a rule of thumb, every 10°C rise or fall in temperature affects a tyre’s pressure by between 1 and 2 PSI. So, the change in your tyre pressure from summer to winter can be up to a 15% difference - that's enough to affect the way your tyres and vehicle perform. Does hot weather affect tyre pressure?

Unless conditions are very extreme, you should be able to drive in hot weather without changing the tyre pressure—as long as you keep monitoring it and watch out for signs of overheating. Bear in mind that the tyre pressure recommended by the vehicle manufacturer is set for cold conditions, so tyres should always be inflated in the shade, and never while the vehicle is still warm from driving.
Jul 1, 2024 · If your tyres are hot, pull over. Pulling off the road and waiting until they cool is the best thing to do when your tyres are overheated. Always change worn tyres. An old, or well-used, tyre, is more likely to leak air. Consider summer tyres. These are better designed and more efficient in hot weather. Keep them clean and well looked-after.
Aug 22, 2023 · Hot weather can have a notable impact on tyre pressure due to the thermal expansion of air. As temperatures rise, the air molecules inside the tyres gain energy and expand, leading to an increase in tyre pressure.
Wet weather can mitigate this somewhat as driving through water dissipates the heat. Change in tyre pressure due to direct sun exposure. The sun’s influence on tyre pressure can make up to 15% difference. Those black tyres in the hot NSW sun absorb the heat, passing it on to the air inside. Automatic tyre pressure monitoring systems
Jul 22, 2023 · Adjust according to the temperature measurements for your region after knowing that a 10-degree Fahrenheit increase results in a 1 PSI (pounds per square inch) rise. For instance, the vehicle dealer recommends keeping the tire pressure at 34 PSI. You will inflate it to 34 PSI when it’s only 30 degrees F outside in January.

When the weather is very hot, the dark asphalt on the road surface absorbs a lot of heat and reaches temperatures of 50°C. At these temperatures the road surface can actually begin to soften and even give the appearance of the road melting. At the best of times, resistance and friction cause a build-up of heat inside tyres which makes the air ...
