You may have heard that tires should be inflated to 80 PSI (pounds per square inch) for better fuel efficiency, or that inflating your tires to 80 PSI can damage the tires and decrease gas mileage.

In this article, we’ll look at answering the question, Should I inflate my tires to 80 PSI?

Should I Inflate My Tires To 80 PSI?

Tire pressure is one of the most important things to get right when it comes to car care and maintenance. The general rule is that you want your tires inflated to their maximum recommended pressure.

Also, tire pressure is measured in pounds per square inch (PSI). The amount of air in a tire is directly related to its size, so the larger the tire, the more air it will hold at a given pressure.

That’s why you’ll see different recommendations for what your tires should be inflated to depending on whether you have a small car or big truck, an SUV, or a minivan.

The recommended tire pressures listed on your vehicle owner’s manual are based on testing by the manufacturer and may not always be accurate or safe for your particular situation.

You should always check with your mechanic before driving with under-inflated tires or over-inflated tires because both conditions can cause serious problems with your car’s suspension system.

What Is Too High For Tire Pressure?

The most common mistake people make when setting their tire pressures is overinflating. Overinflating tires causes them to wear out quicker, make the car harder to handle, and run less efficiently.

Tire pressure is measured in pounds per square inch (psi). The higher the psi, the harder your tires will be working to support the weight of your car.

Tire manufacturers recommend a tire pressure 2-3 psi lower than the maximum pressure shown on the sidewall of your tires. For example, if your tire reads 35 psi max, you should inflate it to 33-35 psi.

Most cars have a sticker in the doorjamb that shows what range is recommended for each tire size and load capacity.

What Does 80 PSI Cold Mean On A Tire?

Tire pressure is measured in PSI, or pounds per square inch. The cold tire pressure is the pressure of the car tires when it’s just been driven for a short distance and the tires are still cold.

The optimum tire pressure for your car should be set by your vehicle manufacturer. The recommended pressure is usually indicated on an information label on the side of each tire.

Tire pressure affects fuel economy and tire wear. If you inflate your tires at the recommended PSI (pounds per square inch), you’ll get better mileage, longer tread life, and improved handling. If you don’t keep your tires at their recommended PSI, they may wear out too soon or not provide optimal fuel efficiency.

What PSI Should Tires Be In Summer?

The proper tire pressure is a very important aspect of your car. It will not only help improve your vehicle’s performance, but it can also save you money on fuel and reduce the risk of getting into an accident.

The best way to check your tires is to use a tire pressure gauge. You can buy one at any auto parts store or online for less than $10.

Using a tire pressure gauge is quick and easy. You simply remove the valve cap from your tire, insert the gauge into the valve stem and note what PSI number it reads on its small display screen.

The recommended PSI numbers vary depending on the vehicle manufacturer, but most vehicles fall between 30–35 PSI for front tires and 35–45 PSI for rear tires when they are new.

When you have run over 10,000 miles on your tires, they tend to lose some air pressure due to normal wear and tear as well as heat buildup during driving conditions — especially if you live in hotter climates like Texas.

Why Do Dealers Overinflate Tires?

Dealers overinflate tires because they want to make them look better than it is. It’s not just a matter of inflating the tire to make it look the same as it did before.

They also want to inflate the tire so that they can sell more products, like extended warranties and other services.

Here are some reasons why dealerships overinflate tires:

They don’t know how much pressure should go in each tire or what kind of pressure goes in what type of car. So, they just put a little extra air in there.
They want to sell you an extended warranty or a service package that includes new tires or alignments.
They want to make sure that your vehicle looks nice for when you take it home from the dealership and leave with a smile on your face after buying a new vehicle from them.

Is It Better To Over Or Under Inflated Tires?

When you’re filling your tires, the recommended tire pressure is the best compromise between handling, comfort, fuel economy, and safety. But it’s certainly fine to go over the recommended inflation by a psi or two. And going over is always better than going under.

The reason is that under-inflated tires are more likely to blow out and cause an accident. They also wear out faster and require more frequent replacement.

And they’re less comfortable because they’re harder to roll on, which causes more vibration in the car’s suspension system and makes for rougher rides.

So what’s the best way to check your tire pressure? It’s not with a gauge but with your eyes and ears. If a tire has too much air in it, you’ll hear a hissing sound when you pump it up — like air rushing into a balloon — and see bubbles coming from the valve stem when you let go of the gas pedal after braking hard.

Should I Overinflate Tires In Winter?

The answer is no, you shouldn’t overinflate your tires in winter.

In fact, underinflating your tires can be more dangerous than overinflating them in winter.

Why? Because underinflated tires have less contact with the road surface and may need to slip and slide to get traction on slippery roads. This means they’ll wear out faster and there will be more heat generated from the friction between the rubber and the pavement — which could lead to problems down the road.

The correct tire pressure for your car’s tires depends on what kind of driving you’re doing: whether you’re commuting or going on a long trip, how fast you’re going, whether you’re carrying lots of cargo, etc. The recommended tire pressure is written on the doorjamb sticker inside your driver’s door.

Why Do Tires Lose Air After Sitting?

Tires lose air for a variety of reasons, but most of them are easily corrected. The following list describes the most common causes of tire failure:

Leaking valve stems: The valve stem is the little rubber tube that connects one side of your tire with the other. It’s usually located at the very top of your tire. If you look closely, you’ll see it sticking out from between two raised ridges on either side.

It has a small cap on top to keep dirt out, so if it’s leaking, it can’t be seen easily. However, sometimes they leak slowly enough that they don’t cause an immediate problem.

If your tires are losing air and you can’t find anything else wrong with them (no cuts in the sidewall), check your valve stems first. The best way to do this is to inflate the tire and let it sit overnight. If it loses pressure during this time, then there’s probably a leaky valve stem somewhere in there somewhere.

Cracked or damaged sidewalls: If you’ve been involved in an accident or hit something hard — like a curb — then it’s possible that one or more sidewalls have been damaged during the impact and now need replacing before they fail entirely (or worse).
