I went to the Washington State Patrol’s police driving teacher program in the early 1980s. During this week-long course, both theoretical and practical aspects of police driving were covered.
Please be aware that the safety and management of state patrol and police vehicles are two of their top considerations.
You can safely run your tire pressure up to the maximum listed on the sidewall while retaining any front-to-rear difference advised by the manufacturer, according to the information they shared with us—information I have employed ever since.
Let’s dissect this using the illustration of a passenger car with sidewall ratings for the maximum pressure of 36 PSI. Let’s also assume that the tire pressure label from the manufacturer inside the door jamb reads 30 PSI front and 32 PSI rear.
This means that you should run the front tires 2 PSI lower than the rear tires in order to maintain the handling characteristics provided by the manufacturer.
You can safely run the rear tires at 36 PSI and the fronts at 34 PSI, retaining the 2 PSI difference advised by the manufacturer, as the tires have a maximum suggested pressure of 36 PSI.
If the front and rear tires on your car are inflated to the same, higher pressure of 36 PSI, as recommended by the manufacturer.
(Under no circumstances can the tires be used at pressures lower than those advised by the manufacturer. Because of the increased rolling resistance, this accelerates tire wear and lowers fuel economy.)
- It increases sidewall stiffness, which helps the tires react quicker to steering inputs and enhances handling.
- Because to the decreased rolling resistance, gas mileage can be marginally improved.
- It makes the ride a little firmer and makes it possible for passengers to feel road imperfections inside the vehicle.
- The core of the tires are NOT worn away by it.
- Even on a hot day, it does not result in a dangerous condition with the tires because you are not going above what their design parameters are.
More and more tires today have a maximum PSI rating of 44. In this scenario, you could choose to run the front tires at 42 PSI and the rear tires at 44 PSI. If you do this, the ride will be substantially rougher and harsher, but the handling will also be noticeably better. By lowering rolling resistance, you’ll probably gain at least 1 MPG.
It’s up to you how you use this information. The remainder depends on your priorities and how you personally strike a balance between handling and ride quality now that you are aware of the SAFE limitations for setting up your tire pressure.
My Murano’s “sweet spot,” as determined by feel from my hands and rear, is 40 PSI all around. It’s a good setup for me and rides and handles well.
On a Nissan Murano, how do you reset the tire pressure indicator?
Turn the key to the “On” position with the car off, but don’t let it run. When the tire pressure light blinks three times, release pressure on the TPMS reset button. Start the vehicle and let it run for 20 minutes to let the sensor reset.
What tire pressure should I use?
It will be helpful to start with the only parts of your car that should be touching the road: the tires, if you’re wondering why your gas mileage has seemed a little lower than usual lately, why your steering feels a little sluggish when you’re behind the wheel, or even why your car just seems to be sitting closer to the ground than usual. Inflation can be a problem for you.
For the best gas mileage and the longest tire life, it’s crucial to maintain the proper tire pressure. The recommended tire pressure for your automobile is printed right on the door of the vehicle and will provide the best handling, gas mileage, and tire life for that particular car. When filling them with air to the advised pressure, expressed in pounds per square inch, or psi, that is the one you should adhere to.
The appropriate tire pressure is typically listed on a label inside the driver’s door of newer vehicles. In most cases, the owner’s handbook contains the specifications if there isn’t a sticker on the door. When the tires are cold, the majority of passenger automobiles advise 32 psi to 35 pressure in the tires. The reason you should check tire pressure when the tires are cold is that as tires roll along the ground, heat is produced through contact with the ground, raising both tire temperature and air pressure. Make sure the car has been sitting overnight or at least for a few hours to get the most precise reading (not to mention the most reliable).
Never fill your tires up to the recommended pressure on the tire. The tire’s maximum allowable pressure, not the recommended pressure for the vehicle, is represented by that number. That was tricky.
Driving on underinflated tires can hasten tire wear due to increased friction, while driving on overinflated tires can offer you a bumpy ride and poorly handled automobile. In any case, not inflating your tires to the recommended pressure will have a detrimental impact on tire wear and vehicle performance as well as your maintenance plan for tire replacement.
What results from excessive tire pressure?
tire overinflation Wear out your tires unevenly and more quickly Overinflation may also be the cause of uneven tire wear. The middle of the tread bows out and wears first when your tires are overinflated. As a result, you will require new tires more frequently and experience a less-than-comfortable ride.
Is 38 psi a high tire pressure?
Hello, Car Talk! Our 2015 Toyota Camry’s owner’s manual advises keeping the tires inflated to 35 psi on all four wheels. Every month when I check the pressure, I find that a few tires may have lost one to two psi. After several attempts, I eventually got exactly that one psi in there as I turn the compressor up. Sometimes while adding air, I’ll overshoot by a half or a full psi, which I then bleed off. Does that need to be done? What tire inflation range between over and under is considered acceptable? — Jay
Jay, you don’t have to do that. You can mess around and get near enough with tire inflation while still leading a full and happy life. Under-inflation of your tires poses the greater risk of the two methods to miss your target.
Underinflated tires run hotter because they have a wider rubber contact area on the road, which increases friction. The belts of the tire may also detach and disintegrate due to heat. The Tire Pressure Monitoring System (TPMS), which is a built-in gauge and a means of communication with the car’s computer, is now a standard feature in every car. Furthermore, a dashboard idiot light turns on whenever any tire pressure falls by around 10% below the acceptable level.
You should let the pressure drop to 31.5 psi before adding air if your Camry calls for 35 psi. On the higher end, your options are more varied. You can overinflate your tires by 10% or even more with little to no repercussions as long as you keep them below the maximum tire pressure indicated on the sidewall of the tire (which is different from the recommended pressure). For instance, if 35 psi is advised yet 44 psi is specified as the maximum safe pressure on your sidewall, you can put 38 or 40 psi in your tires without risk.
The maximum pressure is 44 psi. Although the ride will be tougher, there won’t be a blowout risk. You might even notice faster cornering and better fuel efficiency.
Therefore, the suggested tire pressure is the ideal balance between handling, comfort, fuel efficiency, and safety when it comes to filling your tires. But it’s perfectly acceptable to exceed the advised inflation by one or two psi. Additionally, going over is always preferable to going under.

Is 40 psi too much pressure for an SUV tire?
More than 40 PSI is needed for the tire pressure on pickup trucks and SUVs. Large vehicles must, of course, have over 40 PSI in order to operate efficiently. However, even though a car tire has a maximum PSI capacity of about 60 PSI, doing so is not advised.
You can guarantee the finest tire performance for your car by adhering to these recommendations.
Why are my tires in good condition but my tire pressure sign is on?
It’s likely that one or more of your tires have low air pressure if you see the tire pressure indicator turn on. However, even if your tires are in good condition, there are a number of things that could cause the sensors to go off, so you shouldn’t rely only on the data from the tire pressure monitoring system of your car.
Are tires able to withstand 36 PSI?
“Both the tire label and the vehicle handbook list the recommended cold tire pressure. Typically, a small car requires 30 psi, a medium car 36 psi, and a large car 42 psi.”
Are tires able to withstand 37 PSI?
The psi requirement for the majority of passenger cars will be between 30 and 35 psi, however a number of vehicles fall outside of that range and each vehicle will have unique requirements. A smooth ride, evenly distributed tire wear, and improved fuel economy are all benefits of proper tire inflation.
How much PSI is too much for tires?
For some vehicles with specs within this range, a pressure of 40 psi may be suitable. But for some other tires, this number can likewise be too high or too low.
For example, sports automobiles or passenger cars may be suitable with a pressure level of 40 psi. However, this is too low for heavy trucks and below the recommended pressure of 35 psi for small cars.
The recommended pressure range for tires on well-known sports cars and passenger vehicles is 32 to 40 psi. Depending on the type of vehicle, a specific index will be given. It should be noted that this level is suggested while the tire is cold, so after a lengthy trip, you must check it again to ensure proper adjustment.
There are many various car models available today, and each will utilize a different type of tire. Therefore, the manufacturer will decide in advance what pressure should be used in each of these tires.
It is your responsibility to maintain the best level for the car to run safely and smoothly. To find out whether or not this 40 psi pressure level is good for your car, you must first verify the tire specifications.
Do tires need more than 50 PSI?
We’ll look at some more crucial information in the fine print on the side of your tires today as part of our series on tire information. A rated maximum inflation pressure is specified for each tire. It is frequently written in tiny text around the sidewall’s rim edge. It will read something along the lines of “Max. Load 340 kPa (50 PSI) Max. Press 670 kg (1477 lbs)”. This indicates that the tire may be securely inflated to 300 kPa (Kilopascal), or 50 psi, and will carry up to 1477 lbs (pounds per square inch). For reasons of ride comfort and handling performance, the vehicle manufacturer will frequently specify a little lower pressure on the door jamb label. It can occasionally be beneficial to inflate the tires to a pressure that is closer to the rating on the tire than the rating on the door jamb of the automobile for optimal tread life and fuel efficiency, but doing so might occasionally have a detrimental impact on ride comfort and perhaps traction.
The Department of Transportation (DOT) mandates that each tire sold in the US bear a unique number. The DOT number is a safety certification number that contains details about who made the tire, where it was made, and when (week and year), among other things. If a recall is necessary for a certain batch of tires, this number can be helpful. It is a good idea to register your tires with the manufacturer in case there are any potential safety or recall issues. You can submit a DOT registration card or do it online (provided by your tire installer).
A directional marking is another feature you may notice on some tires. One side of some tires is intended to be positioned towards the inside or outside of the vehicle depending on the tire’s design. These tires should be mounted appropriately because they will either say “Inside” or “Outside” on the tire. Other tires can only be used in a specific direction to deliver good traction and treadwear. These tires are known as directional tires, and they contain a marker on the outside sidewall of the tire—usually an arrow—that indicates which way the tire should be placed for forward rotation.
That’s all there is to it. That is all the information that can be found on the majority of passenger car tires sold in the US. You can now make informed purchasing decisions and dazzle your friends with your tire expertise.
