Most of the time, we don’t think about how the weather affects our cars.
But that doesn’t mean it doesn’t hurt them in any way.
Your tyres’ pressure changes often depending on the temperature. When it’s cold, they lose air pressure.
Every 10 degrees F that the temperature drops, a tyre loses about 2 PSI. Guy-Law Lussac’s says that for a fixed volume, the relationship between temperature and pressure is directly proportional.
Thanks to TPMS, your car probably tells you when one of your tyres doesn’t have enough air in it.
A tyre pressure monitoring system notifies you if tyres lost too much pressure.
Watch your TPMS and fill up your tyres when they get low. That will make them last longer, and it will also save you money on gas.
Why Do Tires Lose Air in the Cold?
We’ve all heard that tyres lose air when it’s cold outside.
It turns out that the rumours about how tyres react to the weather were true. If it’s cold outside, your tyres probably lost some air pressure.
This is because the density of air changes with temperature. When it’s hot, the air spreads out, making it less dense.
When the temperature starts to drop, the air gets more dense.
Less dense air can get out of the tyre more easily.
Plus, even if it’s in the tyre, it will make less pressure.
As long as a system is closed, the pressure is equal to the temperature.
If nothing else changes, a drop in temperature makes the pressure drop automatically.
Your tyres could lose enough air pressure for it to matter. That’s why your TPMS tells you that the pressure has gone down.
Your TPMS will sometimes even tell you which tyres have lost air pressure. If yours does that, filling the tyre is easy.
Just add some air to the one that needs it the most.
Once you’ve filled it up again, the alert should go away.
That’s when you can drive again without risk.
After you drive for a while, your tyres might get their pressure back.
When they drive, they rub against each other a lot, which raises their temperature.
When the air temperature goes up, the air pressure also goes up.
How Can You Stop Your Tires From Losing Air?
During the winter, you might not want to fill up your tyres every morning.
You can keep them from losing air when it’s cold outside by doing a few things.
Don’t go too long without changing your tyres.
The more time has passed since you changed them, the more air they will lose.
Tires aren’t made to last forever, so as they get older, they will start to leak more.
We can’t do anything about how the temperature is causing the pressure to drop.
But if we make sure your tyres are sealed, we can stop them from losing more air pressure.
If you have a hole, make sure the hole is sealed.
If you fix punctures in a flat tyre, you might not need to buy a new one.
Also, you should check how much tread they have.
If they’ve worn down too much, you’ll have to get new ones anyway.
Your tyres should always have a tread depth of at least 3/32 inches. If you have less than that, you could slip and slide on wet roads.
What Should You Do if Your Tires Lose Air?
When it’s cold outside, make sure you check their air pressure often.
Because they lose pressure more often, it’s important to test them.
That’s how you’ll know if they’ve lost too much pressure to drive safely on.
We’d suggest getting a tyre pressure gauge that is easy to keep in the car.
Bring it with you wherever you go in the winter.
If you think one of your tyres is low, check its pressure.
Just screw the pressure gauge onto the inlet valve of the tyre. In a few seconds, it will tell you how much air is in the tyre.
If the air is low, you can use a portable air pump to fill them up.
Most auto parts stores sell them, so it’s not hard to find them.
Most of the time, you can connect them to the AC converter in your car.
If your tyres have lost too much pressure, a portable air pump can make it much easier to fill them up.
You can also check to see if your tyres look low before you get in the car.
When they don’t have enough air in them, they will sag near the bottom.
If their pressure is too low, they won’t hold up the car as well.
You might even notice that when the car is parked, it is sitting on the wheel.
What Happens if You Don’t Refill Low Tires?
If your tyres are low, you need to put more air in them. If you don’t, you’ll tear them apart much faster.
When you drive with low tyres, there is a lot of friction, which tears the rubber.
Adding more air to them shouldn’t cause anything to break.
But you might need new ones if you drive on them.
Another reason to fix flat tyres is that they make your car use more gas. Flat tyres don’t roll well, which makes it harder to get things done.
If your tyres are full, they will use a lot less gas to go the same distance.
So, before you drive, you should make sure your tyres have enough air in them. If they’re full, they’ll last longer!
Also, if they are fully pressurised, you will spend less on fuel.
How Much Pressure Should My Tires Have?
Without looking at the manual, you can’t say how much pressure a tyre should have. Their information is usually in the back of your car’s manual.
Each tyre has a certain pressure at which it works best. Most of the time, it’s between 30 and 40 PSI.
But not all tyres use the same amount of pressure. So, if you need to refill them, it’s very important to check the manual.
If you put too much air in them, they might pop. At the same time, not enough air can also be bad.
But it’s not hard to fill them up with an air pump. They have made air pumps that come with pressure gauges.
So you can see how much air is in each tyre as you fill it up. Stop putting more air in them once they are at full pressure.
If you put more pressure on them than is recommended, it can cut their lifespan by quite a bit.
