How Much Air Should Be In Your Tires

Tires are one of the most important parts of your car, and making sure they’re inflated properly is crucial to your safety and the longevity of your tires. But how much air should you actually put in your tires? The answer isn’t as simple as you might think.

Depending on the make and model of your car, as well as the type of tires you’re using, the recommended tire pressure can vary quite a bit. You can usually find the recommended tire pressure for your car in the owner’s manual or on a sticker inside the driver’s door. If you’re still not sure how much air to put in your tires, it’s always best to err on the side of caution and air them up to the maximum recommended pressure.

This may make your ride a bit rougher, but it will help you avoid a potentially dangerous blowout.

Assuming you’re talking about a car or light truck, the answer is “it depends”. You should check your owner’s manual for the recommended tire pressure for your vehicle. This is usually listed in PSI (pounds per square inch).

In general, you want your tires to be inflated to the manufacturer’s recommended pressure. This will give you the best fuel economy and handling. However, in some cases you may want to adjust your tire pressure.

For example, if you’re going to be driving on a lot of rough roads, you may want to add a few PSI to your tires to help prevent flats. Or, if you’re going to be doing a lot of stop-and-go driving in hot weather, you may want to let a little air out of your tires to help prevent blowouts. As a general rule of thumb, you should check your tire pressure at least once a month, and before any long road trip.

What should your tire pressure be in the summer

It’s no secret that hot weather can do a number on your car. The heat can cause all sorts of problems, and one of the most important things to keep an eye on is your tire pressure. The ideal tire pressure for summer driving is about 32 psi, but it’s always best to check your owner’s manual to be sure.

If your tires are inflated to the proper pressure, they’ll last longer and perform better. Underinflated tires can lead to a blowout, so it’s important to check your pressure regularly. If you’re unsure how to do it, most gas stations have a machine that can help.

If you’re going to be driving in hot weather, be sure to keep an eye on your tire pressure. It could save you a lot of headaches down the road.

Is 40 PSI too high for tires?

If you’re driving on a highway, you should have your tires inflated to about 40 PSI. This is the optimal pressure for tires on a highway. If your tires are inflated to 40 PSI, they will have less rolling resistance and will last longer.

Is 37 PSI too high for tires?

No, 37 PSI is not too high for tires. In fact, most passenger vehicles recommend tire inflation between 30 and 35 PSI. Check your owner’s manual to be sure.

How to Properly Check and Fill Tires on Your Car


Maintaining the proper air pressure in your vehicle’s tires is a crucial aspect of vehicle maintenance that should never be overlooked. The correct tire pressure is essential for ensuring optimal performance, safety, and longevity of your tires. When your tires are underinflated, they do not perform at their best. Insufficient air pressure can cause excessive flexing of the tire sidewalls, which increases rolling resistance. This, in turn, can lead to overheating of the tires, significantly raising the risk of a blowout. A blowout at high speeds can be extremely dangerous, potentially leading to a loss of vehicle control and a serious accident.

On the other hand, overinflating your tires can be equally problematic. When there is too much air in the tires, they become rigid and less able to absorb the impacts from road irregularities. This can result in a harsh and uncomfortable ride, as every bump and pothole is felt more intensely. Additionally, overinflated tires have a smaller contact patch with the road, which can reduce traction. This diminished traction is particularly concerning during adverse weather conditions or emergency maneuvers, where maximum grip is essential for maintaining control of the vehicle.

To ensure that your tires are always at the correct pressure, it is vital to check them regularly. The frequency of these checks can vary depending on how often you drive, but a good rule of thumb is to inspect your tire pressure at least once a month and before long trips. Most vehicles are equipped with a Tire Pressure Monitoring System (TPMS) that alerts you when the tire pressure is too low. However, relying solely on this system is not enough, as it may not provide warnings for over inflation or slight deviations from the optimal pressure.

Consulting your car’s owner’s manual is the best way to determine the recommended tire pressure for your specific vehicle. The manual provides detailed information on the proper inflation levels for both the front and rear tires, as well as for different load conditions. This information is typically also available on a sticker located on the driver’s side door jamb or inside the fuel filler door. Using a reliable tire pressure gauge, you can measure the current pressure and compare it to the recommended levels. If necessary, adjust the pressure by adding or releasing air until it falls within the specified range.

In summary, maintaining the correct tire pressure is a simple yet vital task that enhances your vehicle’s performance, safety, and comfort. By regularly checking your tire pressure and consulting your car’s owner’s manual, you can avoid the pitfalls of both underinflation and over inflation, ensuring a smoother and safer driving experience.
