Maintaining correct tire inflation pressure is very important since it helps optimize tire performance and fuel economy while over-inflated tires are just as problematic as under-inflated ones.
In fact, driving with under-inflated tires is one of the biggest causes of tire failure, according to the National Highway Traffic Safety Administration.
Besides, under-inflated tires can cause many other problems such as wearing out more rapidly, handling poorly and reducing fuel efficiency.
In addition, over-inflated tires are more susceptible to damage from road irregularities, and this also creates a bumpier ride.
Overfilling your tires is just as dangerous as under-filling them, so it’s important you know what is recommended for your vehicle.
This article will give you everything that you need know about your recommended tire pressure. These include:

Recommended tire pressure, where to find it?Since tire pressure is so important to your safety and your car’s overall performance, it is important to know which level of tire pressure is right for your vehicle.
In fact, how much air pressure your tires need depends on several factors, including the type of vehicle, the type of tire and the intended use of the vehicle etc.
Air pressure in tires is measured in pounds per square inch or PSI. You can find your tire pressure both inside your car and on the sidewall of the tire.
How to find recommended tire pressure inside your carYou could find the manufacturer’s optimum or recommended tire pressure for your car on a sticker in the door jam, or in your owner’s manual. Some car models even place the stickers on the trunk lid, in the console or on the fuel door. For best results, look for a placard on the inside of the driver’s door, like the example in the photo below.
How to find maximum tire pressure on the sidewall of your tiresSomewhere on the sidewall of your tire, just below the big, bold letters of the manufacturer, for example, you might have noticed the words ‘Max.
Press. 35 PSI.’ (pounds per square inch).
That number tells you the maximum cold pressure needed for your tire to carry its maximum load.
Most typical tires require about 32 to 35 pounds per square inch (PSI) of air, says Rod Tate, owner of highly rated Colony One Auto Center in Stafford, Texas.
Large trucks require much larger tires with PSIs of 50 to 60. Heavy-duty vehicles can go even higher. For example, tire in the picture below requires 41 pounds per square inch of air.
However, the tire’s maximum pressure is NOT necessarily the most suitable pressure for every vehicle upon which the tire can be used (almost all vehicle manufacturers’ recommended tire inflation pressures are less than the tires’ maximum pressure).
You really should follow the recommended pressure printed somewhere inside your car or in the manual rather than the maximum pressure. In the next section, I will explain why.

Why is maximum tire pressure not the best?If you insist on inflating your tires to the max PSI, there will be more likely that two things below will happen
Since tires inflated to the max cannot give as much on the sidewall, you might see superior cornering, but it could be at the risk of your braking threshold.
One quick corner and your back end could slide out.
When your tires are inflated too much, the rubber rounds out at the top of the tire when you are driving, and the center will quickly wear out. You will also reduce your traction and you could even cause a blowout.
Therefore, maximum pressure is not the best, rather, recommended pressure is. I need to repeat here that the pressure listed on the sidewall is a maximum pressure only, but not a recommended pressure. Instead, you should use the air pressure recommended in the vehicle’s owner’s manual or tire information placard label.
How to check your tires pressure?Therefore, maximum pressure is not the best, rather, recommended pressure is. I need to repeat here that the pressure listed on the sidewall is a maximum pressure only, but not a recommended pressure.
Instead, you should use the air pressure recommended in the vehicle’s owner’s manual or tire information placard label.
After knowing the most appropriate pressure for your car tires, you should check whether your tires have such pressure. In addition, checking the pressure of your tires regularly is one of the most important – and most often overlooked – regular maintenance that you should do to ensure your safety and quality of your driving. Monitoring the amount of air in your tires will let you know if you have a small leak and can help you avoid an unexpected flat tire.
Frequently checking your PSI becomes even more important in the fall and winter, when outside temperatures drop and weather conditions fluctuate causing your tires to lose air more quickly. Generally speaking, your tire will gain or lose one PSI for every 10-degree change in temperature, which means if you have a sudden drop of 30 degrees, you could lose three PSI overnight. If your tires were already low, this could cause tire damage, steering problems or even a flat tire.
Some experts recommend that you should check the air pressure every time you refuel; others say once a month is sufficient.
How to check tire pressure properly? Checking tire pressure is easy. You can do it right at home or at the gas station. Just be sure you check the pressure when your tires are cold, or have not been driven in several hours. This will give you the most accurate reading.
The most important piece of equipment you need is an accurate tire pressure gauge. You can find battery-operated digital gauges, or more traditional stick-type gauge found at most gas stations. A good gauge should not set you back more than $15 – a worthwhile investment for a longer life for your tires.

Make sure you have your manufacturer’s PSI handy when you are checking your tire pressure, and then follow these steps:
By checking tire pressure once a month, you will get a good idea how they are performing. If your tires are fairly new and continue to leak air, you should consult your dealer or mechanic. You may have a faulty valve or other damage that is difficult to detect which could unfortunately result in the need to replace the tires completely.
But with proactive maintenance, you could catch an issue before it becomes a problem, and just end up needing a small repair.
Often, it is hard to spot an under-inflated tire until it is too late – in other words, it is completely flat. Of course, you could carry a gauge around at all times to measure the pressure, but that is not exactly convenient. Instead, watch for these signs and symptoms of tires that are under-inflated.
When your tires are under-inflated, your ride can be less smooth than usual. You may even find that it takes longer to brake.
When a tire is not inflated properly, it wears down more quickly. If you notice that one or all of your tires are wearing out faster than usual, it may be because they are under-inflated.
Tires that are under-inflated can make your vehicle quiver and shake, which is not a pleasant driving experience.
Under-inflation can even cause tires to become misaligned, with comes with it is own variety of problems.
These are all things that you need to know about recommended pressures of your car tires. After reading this article, you will never confuse about the right pressure of your tires and will know how to check it.

The recommended tire pressure is the pressure established by the manufacturer of your car as the optimal air pressure for your tires. Running your tires at the correct pressure is important because it keeps you safe, cuts down your gas bill, and makes your tires last longer. Each vehicle has its own specifications for tire pressure, but most fall between 28 and 36 PSI (pounds per square inch).
Be careful not to confuse the recommended pressure with the maximum pressure.
The recommended pressure is the one you should use when filling your tires, and, as explained above, you can find on your doorjamb or in your owner’s manual. The maximum pressure, on the other hand, is usually stated on the sidewall of the tire itself in small print near the tire’s bead (where the rubber abuts the rim). This measurement is provided by the tire manufacturer rather than the car manufacturer and is the maximum amount of pressure the tire can safely withstand.
Your tires’ max PSI almost always exceeds the recommended pressure. It isn’t advisable to fill your tire to this pressure for everyday driving. At max PSI, your car does not handle as well, braking is impaired, and you could risk dangerous blowouts. Over-inflation can also cause the center of your tire’s tread to wear out prematurely and reduce the lifespan of your tires. You may want to use the max pressure on a temporary basis if you are hauling especially heavy load or towing something.
Most manufacturers do not state a minimum tire pressure, per se. The recommended value is the amount of air that a tire needs for a car to handle properly and safely, and anything under that value is not recommended, so functionally the optimal value is also the minimum. Under U.S. law, vehicles are required to be equipped with tire pressure monitoring systems (TPMS) that warn the driver when tire pressure falls below 25 percent of the recommended PSI. This is considered severe under-inflation, but less drastic pressure drops are still considered moderate or mild under-inflation, and they and can still have negative consequences.
If your tires are inflated to a pressure that is below the recommended PSI (as shown in the manual or on the driver’s side doorjamb), your car will not operate safely. Under-inflation can cause the tire to heat up excessively, which can make the tread pull away from the body of the tire.
If this happens on the highway, it could lead to a blowout and a serious accident. There are also financial reasons for making sure your tires aren’t under-inflated. A low tire has more rolling resistance, which means the car has to work harder to move down the highway and consumes more fuel. Well-inflated tires are going to save you money at the pumps. Low tires also wear more quickly and unevenly, so you will have to replace them more often.
A tire pressure monitoring system (TPMS) uses either a direct sensor inside your valve stem or a combination of both software and other existing sensors in your vehicle to let you know when your tire pressure is outside of a safe range of pressures. If the pressure falls below the legally specified limit (25% of recommended pressure) an indicator light shaped like the letter U with an exclamation point inside it (representing the cross-section of a tire) will light up on the dashboard.
When you see this TPMS light on you should immediately check your tire pressure and make any necessary adjustments.
If you have further questions about tire pressure or any other aspects of your tires, find your nearest tire dealer to get some advice.
There is a tire pressure mark on the sidewall of your tires, but this is not the optimal air pressure for your tires, but the maximum. The words "Max. … 35 PSI, for example, means the maximum pressure in psi your tire needs to support its maximum load capacity of .
Likewise, is 36 psi too much? High pressure is generally not dangerous as long as you stay well below the "maximum internal pressure". That number is printed on each sidewall and is much higher than your "recommended tire pressure" of 33 psi, Gary. So, in your case, I would recommend that you put 35 or 36 psi in the tires and just leave it there.
Tire pressure 31 too low? it's too low .
Most tire pressure monitoring systems alert you when tire pressure drops by about 10 percent. For you, 10 percent would be a little less than 30 psi. Low tire pressure is always more dangerous than high tire pressure.
Tire pressure 28 low? Most passenger cars recommend 33 to 35 psi. At 28 psi you is running a little low and really should get them back on the air. It's not what I'd call alarmingly low, but anything more than three or four pounds below normal can cause handling problems and increase the chance of an explosion.
Second, is 5 psi too much? While 5 psi doesn't seem overly low, remember that typically 5 psi is about 20% of the recommended tire pressure for . An over-inflated tire is stiff and the ride will be rough. … On the other hand, higher tire pressure generally improves agility and handling.
If there is no sticker, you can usually find information in the owner's manual. Normal tire pressure is typically 32 to 40 psi.
(psi) when cold. So be sure to check your tire pressure after a long stay and this can usually be done early in the morning.
then must all 4 tires have the same PSI? tire manufacturer's maximum tire pressure. Very small numbers. Yes, all pressures must be the same . If you have 4 wheel drive or 4 wheel drive, front and rear tire pressures MUST be the same to prevent transmission damage.
At what PSI will a tire explode? A stock tire is inflated to about 30-35 psi. In hot weather and highway conditions, the air temperature inside the tire rises by about 50 degrees. This increases the pressure inside the tire by about 5 psi. Tire burst pressure is about 200 psi .
One thing that is important for proper driving conditions is proper tire inflation and pressure. The ideal pressure range in cars is between 193-234 in kPa (kilopascals) or 28 to 34 psi (psi). However, in heavier vehicles such as minivans, the pressure can be higher, up to 303 kPa (44 psi).
What is unsafe tire pressure? If you have standard passenger tires (% of cars have them), the lowest tire pressure you can normally drive with is 20 pounds per square inch (PSI). Anything below 20 psi is considered a flat tire and puts you at risk for a potentially devastating blowout.
What is the lowest PSI you can ride?
If you have standard car tires (ninety percent of cars), the lowest tire pressure you can normally drive with is 20 psi (PSI). Anything below 20 psi is considered a flat tire and puts you at risk for a potentially devastating blowout.
Why do dealers inflate tires too much? Short answer: when they service and change the oil the tires are usually hot . The PSI in your door is for the cold (the car has been sitting all night). If you have hot tires, the pressure will be higher than if you have cold ones. So when they fill the tires, they do so to the appropriate "hot" level.
Each tire has nominal maximum inflation pressure.
… This means the tire will safely handle up to 1477 pounds. and can be safely inflated to 300 kPa (kilopascal) or 50 psi (psi).
Should tires be inflated in winter?
Inflated tires in winter
Although it is never good to inflate a tire, especially dangerous during the winter months . The snow, ice, salt and sand that accumulate on normally clear roads in winter can reduce traction, meaning you'll have to do whatever it takes to get the most traction.
Why do mechanics pump tires? The short answer is that when they service and change the oil the tires are usually hot . The PSI in your door is for the cold (the car has been sitting all night). If you have hot tires, the pressure will be higher than if you have cold ones. So when they fill the tires, they do so to the appropriate "hot" level.
Can tires be inflated? Inflating tires can make them more vulnerable to damage. … Excessive air pressure can also deform the shape of the tire, resulting in reduced traction and increased wear on the center of the tire.
One thing that is important for proper driving conditions is proper tire inflation and pressure.

Can I drive with uneven tire pressure? Why you Do not drive with low tire pressure
An accident like this can cause you to lose control of your vehicle at high speed, endangering yourself, your passengers and others on the road. In addition, low tire pressure has a negative effect on fuel economy and leads to faster tire wear.
Do wider tires need more psi?
To explain optimal tire pressure in simple terms, think of it this way: the load of any vehicle is supported by the amount of air in the tires. … Therefore, a larger tire requires less pressure than a smaller tire for the same vehicle weight.
Is it normal to have uneven PSI in your tires? The tire bulges in the center of the tread when you over-inflate it. … This means center tread wear, an uncomfortable ride and an increased risk of blowouts. Note that tire pressures a few pounds per square inch higher than recommended usually won't put you in the danger zone. .
Aircraft tires are subjected to very high loads during takeoff and landing. When landing, the intense friction on the runway and the brakes creates very high temperatures in the aircraft's tires. … Tires filled with nitrogen to prevent fires from extreme heat .
4 PSI too much? you have to go is above 5 pounds but 35 pounds is generally a good number for fuel economy and handling in most small cars. Everything is a compromise. If you overinflate your tires, you will have less traction and the tires will wear unevenly, wearing out faster in the center.
I want to know what is the lowest tire pressure you could put on a top speed 44psi tire? I run these tires at 33-34 psi.
inch for about half a year now, will it damage my tires? I plan to install 36 psi. inch to make it close to the nominal maximum limit.

Tire pressure is usually determined by vehicle weight and tire type. In other words, 44 psi. in. (44 psi) is the maximum tire pressure at its maximum load.
You can safely inflate tires to maximum pressure, but this may not provide the best ride or performance. Each vehicle has a specified pressure/load rating on a plate located in the jamming area of the doors. It might look like this;
Since you haven't given us any information about the type of tire or vehicle, I will say that you should use 10% to 15% pressure at maximum psi to get the best ride or tire performance.
This is just a guess and you will have to do a little research yourself depending on the brand of tire and vehicle type.

Tire pressure should only be appropriate for vehicle weight/ground area per tire/4 tyres. However, cornering can increase tire inertial mass and increase friction wear and life.
The pressure is therefore a compromise between gentle shock absorption and long-term comfort. Using the recommended pressure can optimize service life. But not comfort, but the number of passengers + luggage can make a difference.
Optimum tire pressure depends on how you ride corners and absorb bumps that cause rim damage, not highway comfort and vibrations.

38psi seems to be perfect for a tire with 44psi max cold.
It is recommended to check between winter and summer. Technically, you should check every month, but how many of us do this. My truck, which has a tire rating at 80psi cold, seems to do best in the 50-60psi range. When you start getting around 7 70-80psi you are in for a pretty tough ride. It can also add unnecessary stress to the shocks/bars and general suspension components. Note: If you tend to haul heavy loads, you may want to be a little higher in FPS. inch but never exceed the maximum cold figure and remember to check when the car is idle like at night and check before the sun can affect anything.

I have a 2011 vagrant synthesis. The tires have a maximum sidewall pressure of 44 psi. inch, and the sticker on the door is 31 psi. inch. A big difference! At 60,000 miles, the tread on the outside is next to the wear indicators, and the tread in the middle is probably only halfway down. When I look up why tires wear so much, I find it is usually due to insufficient ventilation. Getting ready to get new tires and will definitely keep them close to 40 psi. inch.

The door will have the original tire that came with the car if you put the original tires they call back when you need new ones. you will probably keep the same specs when you change tire brands and different sizes, the manufacturer will give you the specs for this tire, and the safety of this tire, I always go to buy tire specs, check the tire sidewall pressure by them, you can still call the tire factory that makes this brand of tire that would be better than everyone here, just guessing.
