How Do Weather Conditions Affect Your Car Tyre Pressure?

As a driver, you may have noticed that your car's tyre pressure decreases or increases with changing weather patterns. Unbelievably, tyre pressure is a critical component of your journey's safety. A flat, over-inflated tyre can cause accidents, decrease fuel efficiency, and wear your tyres more quickly. 

This blog will be exploring how weather conditions affect your car Dunlop sp sport lm705 tyre pressure and how you can maintain optimal tyre pressure all year round. 

Changes in Atmospheric Pressure 

The air pressure surrounding the earth is known as atmospheric pressure. Atmospheric pressure conditions change with changing weather patterns. Changes in atmospheric pressure subsequently led to fluctuations in tyre pressure. For example, during wintry weather, the atmospheric pressure is lower, and because of that, your car tyre pressure may also decrease. In contrast, during hot weather, the atmospheric pressure is higher, and your car tyre pressure may increase. 

Warm Weather and Tyre Pressure  

As the temperature rises, the air inside your car tyres tends to expand, leading to an increase in tyre pressure. This is because the heat causes air molecules to move faster, increasing pressure. Therefore, it is recommended that you check your tyre pressure regularly during the warmer months and adjust it accordingly to ensure optimal driving performance and safety. 

Cold Weather and Tyre Pressure  

Just like warm weather affects tyre pressure, wintry weather can also have an impact. When the temperature drops, the air inside your car tyres contracts, leading to a decrease in tyre pressure. This can lead to decreased traction, increased wear and tear, and reduced fuel efficiency. To prevent this, make sure to check your tyre pressure regularly during the colder months and ensure that it is adjusted to the manufacturer's recommended pressure. 

Rainy Weather and Tyre Pressure  

Rainy weather can also have an indirect impact on your car's tyre pressure. Puddles and wet roads can cause hydroplaning, which can increase the wear and tear on your tyres and lead to a decrease in tyre pressure. Additionally, driving through water can also cause water to enter your tyre valves, causing a decrease in tyre pressure. Therefore, it is crucial to check your tyre pressure regularly during rainy weather, especially after driving through water. 

Changes in Temperature Affects Tyre Pressure 

Temperature plays a significant role in tyre pressure. When the temperature rises, the tyre pressure increases, and when the temperature decreases, the tyre pressure decreases. Therefore, if you have recently inflated your tyres during hot weather and then drive in colder conditions, you will notice that the tyre pressure has decreased. 

It is important to note that pressure measurements made when tyres are hot can be falsely elevated because of the increased temperature. Therefore, tyres must be checked when they are cold and have not been driven for at least 3-4 hours. This will provide an accurate tyre pressure level. 

Changes in Humidity Levels 

Humidity is an important driving factor for tyre pressure. Tyre pressure mass increases with increased humidity levels, causing low tyre pressure. Humidity can affect the tyres of your vehicle similarly to the way moisture condensation can form on windows during chilly winter weather. It would be best to consider the effects of humidity when checking your tyre pressure. 

Altitude Affects Tyre Pressure 

Another factor that affects your car tyre pressures is altitude. At higher altitudes, atmospheric pressure is lower, causing lower tyre pressure, while at lower altitudes, atmospheric pressure is higher, leading to higher tyre pressure. Therefore, if you have been driving up a mountain, you should check your tyre pressure to ensure that it has not been negatively affected. 

How to Maintain Optimal Tyre Pressure 

It is essential to maintain optimal tyre pressure to ensure that you are driving under safe and optimal conditions. A useful tip to maintain optimal tyre pressure is to check your tyres once a month. In addition, check your tyres when they are cold and have not been driven for three to four hours. 

It is also vital to inflate or deflate your tyres according to the manufacturer's recommendations, which can be found in your vehicle's owner's manual. Over-inflation decreases the surface area of the tyre, giving it less traction, and could even result in a blowout. On the other hand, underinflation could cause your tyre to become too flexible, resulting in faster tyre wear and reduced fuel efficiency. 

Conclusion: 

Your car tyres are a defining factor regarding the safety of your driving. Maintaining optimal tyre pressure levels is key to ensuring your safety on the road. As discussed, weather patterns have a significant impact on your tyre pressure. Understanding the effects of humidity, temperature, altitude, atmospheric pressure changes, and how to maintain optimal tyre pressure can help prevent or reduce the risks of accidents and servicing your tyres. Regularly checking your tyre pressure will allow you to drive safely and maintain the performance of your vehicle.
