How Long To Wait For Tires To Cool

how long to wait for tires to cool

Whether it is cool or hot weather, it is possible that there will be a difference in the tire pressure when you measure it.

One thing to note is that you cannot just measure the tire pressure after you have been driving for hours. There is a need for waiting for these tires to cool first.

So, how long does it take for the tires to cool before you can measure the tire pressure?

It is advisable that you wait for at least two to three hours for the tires to cool before measuring the air pressure in the tires.

As much as waiting for three hours is recommended, you can also find exceptions to this rule.

A good example is if you have only driven the car for a few miles while maintaining a slow speed. The result is that you can still get an accurate reading of the tire pressure if you just wait an hour for the tires to cool.

It might not be the same if you had been driving in hot weather for several hours. In such a case, it is best to wait even four hours for an accurate reading.

It is vital that you always perform the recommended checks on your tires more often rather than waiting until something happens before taking action.

So, how often should you check the tire pressure?

We can recommend checking once every two weeks. This should be enough to notice any drop in the air pressure and take the appropriate measures to have the tires in good working condition.

How Temperature Affects Tire Pressure

A rise or decline in temperature can have an influence on the amount of air pressure in the tires. That is why you always have to take the reading when the tires are cold.

It is estimated that there will be a 1 PSI difference for a change of 10 degrees F in the temperature. So, if the outdoors change by 30 degrees F, expect a change of 3 PSI.

You can always be on the lookout for information from the TPMS system. This is if you have one installed in your car. If there is a low tire pressure warning, have it addressed as soon as possible.

Here is how the TPMS works

Correct Air Pressure

The correct air pressure is relative depending on the type of vehicle you are using. Some vehicles would be 40 PSI while others more.

Like for passenger cars, it is advised to keep the tire pressure around 32 to 40PSI. The trucks on the other hand might need 10PSI more to be good enough to drive around without a problem.

You could also get the air pressure information from the driver-side door label. It will tell more information about the best pressure for the front and rear tires.

Here is how you can check the tire pressure

Now that you have checked the tire pressure, it is vital to inflate them correctly. It is possible that at times the tires might be overinflated or underinflated.

In the case of overinflated tires, it means that only the middle part of the tread area is in contact with the road surface. This leaves you with tires that can wear faster in that middle section only.

As for the underinflated tires, the wear is on the sides of the tire while the middle section remains unused.

In both cases, you now end up with uneven wear. That is not good for the car’s handling, braking, and steering. Sometimes there could be blowouts too.


Can a tire lose air pressure overnight?

It can depend on the weather conditions. An example is if the weather is too cold to the point it is freezing. It is estimated that the tire loses 1 PSI for every drop of 10 degrees F.

Can the air pressure in the tire increase as you drive?

Yes. Each time you drive, the tires get hot which means that the tire pressure can expand and increase too. However, it is not too much to get you worried.

How often to check tire pressure?

You should check tire pressure every two weeks if you want to ensure the tire pressure is maintained in the right range always.
