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.

What pressures should the tires on my Honda be at?
The Civic and Accord, two of the most popular Honda automobiles, need 32 PSI (pounds per square inch). The tires on Honda SUVs like the Passport and Pilot need to be inflated to 35 PSI.
Is the tire pressure of 36 too high?
Both the tire label and the car 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.
Depending on the size of the car and its tires, different tire pressures are advised. Small automobiles often have a 30 psi tire pressure, medium-sized cars typically have a 36 psi tire pressure, and large cars typically have a 42 psi tire pressure.
Remember that the recommended cold tire pressure is typically exceeded by 4-6 psi by heated tires.
When your automobile has been idle for at least three hours or you have only traveled 1.6 kilometers, your tires are deemed cold.
The owner’s manual for your vehicle and the tire label on the center pillar on the driver’s side both list the recommended cold tire pressure.
Uneven wear occurs in tires with excessive or inadequate pressure. Uneven tire wear can result in poor handling, a loss of vehicle control, and unexpected tire failures, all of which have the potential to cause collisions, injuries, and even fatalities. Therefore, you should at least once a month check your tires. As follows:
1) Have a high-quality gauge ready to check tire pressure on a cold tire.
– A quick glance at your tires won’t reveal whether they are adequately inflated.
2) Take off the tire valve’s valve cap.
3) To measure the pressure, put the tire gauge against the valve. You’re done if the reading agrees with the advised pressure.
4) If the pressure is too low, add air to the container until the pressure is appropriate.
Pushing on the metal stern in the middle of the tire valve will release air if the pressure is too high.
5) Use the tire gauge to check the tire pressure once more.
6) Reinstall the valve caps on the valves to help stop leaks and keep out moisture and debris.
What results from excessive tire pressure?
Less of the tire contacts the ground if tire pressure is too high. Your automobile will consequently jolt around on the road. Additionally, grip is hampered and stopping distances increase when your tires are bouncing rather than being securely planted on the pavement. Additionally, the comfort of the ride will lessen.
What is a low tire pressure?
Your tire pressure light illuminated the other morning when you turned on your automobile to drive to work. This time of year, when temperatures are falling and tire air is cooling and contracting, that is not unusual. However, the light continues to be on, leaving you to question if you should top off your tires with a little extra air or if you can just continue driving on tires with low pressure. How low is low, if at all? When does low tire pressure make it too risky to drive on?
Protecting auto warranty companies According to My Car, the longer you ignore low tire pressure, the greater risk you put yourself in for everything from decreased gas mileage to a possibly disastrous blowout! … Although maintaining adequate tire inflation and checking your tire pressure is a nuisance, it is much simpler than having to deal with the effects of having under-inflated tires. Low tire pressure can have a detrimental impact on safety, handling, tire wear, and fuel efficiency.
Low tire pressure can also impair a vehicle’s responsiveness and traction, making it more challenging to escape accidents (think switching lanes last minute in traffic or dodging a pothole). Additionally, less traction means that your car’s engine will work harder and consume more fuel than necessary.
If you have normal passenger tires, which 90% of vehicles do, the lowest tire pressure you may typically drive with is 20 pounds per square inch, advises Protect My Car (PSI). A flat tire is defined as having less than 20 PSI, which puts you at risk of a possibly disastrous blowout.
So what should a driver do if their TPMS light illuminates? So, check your tire pressure yourself or have someone else do it. Before you drive, you should have the tire fixed if it is significantly too low. Before you travel a great distance, you should go top off the air in the car if there is still enough air in it. Additionally, you might want to get the tire(s) inspected to make sure the issue is not a gradual leak or another problem, but rather the cooler weather.

Are tires able to withstand 38 PSI?
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.
Which is preferable, under- or over-inflated tires?
Maintaining the ideal tire pressure can significantly increase fuel efficiency, road comfort, and even tire life. But how do you know the ideal tire pressure?
If your tires are under-inflated, the reduced tire pressure may put extra strain on the tire’s side wall. The portion of the tire’s tread that is intended to contact the ground is where tires are supposed to have tread. When you drive or turn your wheels, the sidewall of the tire may come into contact with the pavement if there is not enough air in it.
The tire’s side wall is frequently thinner than its outside. Without the tread to shield it from hazards on the road, the side wall will swiftly deteriorate and wear out. Your car is far more likely to experience a blowout when the tire gets too thin or a flat tire due to hazards on the road.
The tire might potentially be dangerously overinflated. The internal pressure puts the tire at risk if the tire is overinflated. Once more, it influences how the tire contacts the ground. Overinflated tires for your vehicle will feel like walking on your tiptoes or in very high heels. When your tires are overinflated, you’ll probably feel every bump in the road and struggle to steer and control your car.
The ideal tire pressure gives you good handling and comfort on the road. By lowering the tire’s resistance to the road, it also helps to increase fuel efficiency. To prolong the life of your tire and avoid premature or uneven wear, make sure the tire is properly inflated before it reaches the road.
Never rely solely on the tire pressure recommended on the tire.
This represents the highest inflation pressure that the tire can safely withstand, NOT the correct inflation for your car.
The ideal tire pressure will be specified by your vehicle’s manufacturer in the owner’s manual. This information might also be located on the fuel door, glove box, door post, or edge of the automobile door.
