Should You Put Air in Your Tires When It’s Cold?
As the weather turns colder, many drivers wonder if they should add air to their tires. After all, tires lose pressure as they cool down. So, it makes sense to assume that you should add air to compensate for this loss. However, the truth is a bit more complicated.
The Real Answer
The short answer is: It depends. You should check your tire pressure regularly, regardless of the temperature. If your tires are underinflated, you should add air to them. However, if your tires are already at the correct pressure, you don’t need to add any more air, even if the temperature drops.
Understanding Tire Pressure
Tire pressure is measured in pounds per square inch (psi). The recommended tire pressure for your vehicle can be found on a sticker inside the driver’s door jamb. It is important to maintain the correct tire pressure because it affects the handling, stability, and fuel efficiency of your vehicle.
When tires are underinflated, they can cause a number of problems. Underinflated tires can:
- Increase rolling resistance, which reduces fuel efficiency.
- Cause uneven wear on the tires.
- Make your vehicle more difficult to control, especially in wet or icy conditions.
When tires are overinflated, they can also cause problems. Overinflated tires can:
- Reduce traction, which can make it more difficult to stop your vehicle.
- Increase the risk of a blowout.
- Make your ride more uncomfortable.
The Impact of Cold Weather on Tire Pressure
As the temperature drops, the air inside your tires contracts. This causes the tire pressure to decrease. The amount that the tire pressure decreases depends on the temperature and the size of your tires.
For example, a 10-degree drop in temperature can cause the tire pressure in a typical passenger car tire to decrease by about 1 psi. This may not seem like a lot, but it can make a difference in the handling and performance of your vehicle.
When to Add Air to Your Tires
If you’re not sure whether or not you need to add air to your tires, the best thing to do is to check the tire pressure. You can do this with a tire pressure gauge. Tire pressure gauges are available at most auto parts stores and service stations.
If your tire pressure is below the recommended level, you should add air to your tires until they reach the correct pressure. You can use a tire inflator to add air to your tires. Tire inflators are available at most gas stations and car washes.
Tips for Maintaining Tire Pressure
Here are a few tips for maintaining the correct tire pressure:
- Check your tire pressure regularly, especially when the temperature changes.
- Keep a tire pressure gauge in your car so you can check your tire pressure whenever you need to.
- Add air to your tires until they reach the correct pressure, as indicated on the sticker inside the driver’s door jamb.
- Don’t overinflate your tires.
- Rotate your tires regularly to ensure even wear.
FAQs
Q: How often should I check my tire pressure?
A: You should check your tire pressure at least once a month, and more often if you’re driving in extreme conditions.
Q: What happens if I don’t maintain the correct tire pressure?
A: If you don’t maintain the correct tire pressure, you can experience a number of problems, including reduced fuel efficiency, uneven tire wear, and decreased handling and stability.
Q: What should I do if my tire pressure is low?
A: If your tire pressure is low, you should add air to your tires until they reach the correct pressure. You can use a tire inflator to add air to your tires.
Conclusion
Whether or not you need to add air to your tires when it’s cold depends on the temperature and the size of your tires. If you’re not sure whether or not you need to add air, the best thing to do is to check the tire pressure. If your tire pressure is below the recommended level, you should add air to your tires until they reach the correct pressure.
So, the next time you’re wondering whether or not you should put air in your tires when it’s cold, just remember to check the tire pressure. It’s the only way to be sure.

Why Does My Tire Pressure Light Come On When It’s Cold Outside? Remove the valve cap from your tire, and attach the tire pressure gauge to the valve stem. There will be a brief hiss of air, but keep pressing until the hiss stops. Once it stops, you’ll know that the gauge is correctly attached and it will display an accurate pressure reading. If your tire pressure is lower than recommended, then go ahead
