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.

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 listed right on the door of the vehicle and will provide the best handling, gas mileage, and tire life for that particular vehicle. You should follow that guideline when filling up.
The recommended pressure is typically displayed on a sticker 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, most passenger cars advise 32 to 35 pressures in the tires. Since friction between tires and the road causes heat to be produced as they roll along the road, you should check the tires’ pressure when they are cold. Make sure the automobile has been parked for several hours or at least over night for the most accurate tire-pressure reading.
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.
Under-inflated tires might prematurely deteriorate due to increased friction, while over-inflated tires can offer you a bumpy ride and poorly handling automobile. Both tire wear and vehicle performance may suffer if your tires are not inflated to the proper pressure.

What PSI will cause a tire to blow up?
An average tire has a pressure of 30 to 35 pounds per square inch. The temperature of the air within the tire rises by roughly 50 degrees in hot weather and on the highway. This results in a 5 psi rise in tire pressure. A tire’s burst pressure is roughly 200 psi.
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.
36 PSI—is it too much?
Hello, Car Talk!
33 pounds of air should be in each of my 2017 Toyota Tacoma’s four tires. Within two or three days, the temperature where I live can go from a high in the 70s to a low in the 20s and back to a high in the 50s. Tire pressure is difficult to manage as a result. What are the safe upper and lower limits for tire pressure, please? I’m aware that if I use 35 psi, the ride will be difficult and I’ll get better gas mileage. I’ll get lesser gas mileage and a softer ride if I choose 29 psi. But when do I truly need to modify it, in either way, for safety? Gary
When it comes to tire pressure, Gary, it’s always preferable to go too high than too low (to a point).
As you mentioned, tire pressure varies with the weather outside. Tire pressure changes by around 1 psi for every 10 degrees change in ambient temperature. The pressure on your tires will be 28 psi if you fill them to 33 psi while it’s 75 degrees outside and 25 degrees at night. That is too little.
According to what I’ve heard, the majority of tire pressure monitoring devices alert you when your tire pressure drops by roughly 10%. You would need about 30 psi to equal 10 percent.
Always, low tire pressure is riskier than high tire pressure. Deflated tires have more rubber in contact with the ground, which increases tire heat and increases the risk of a blowout. If you recall the Firestone/Ford Explorer scandal, heat (high road temperatures) and low tire pressure were the aggravating conditions that caused many of those defective tires to explode.
In general, higher pressure is not harmful as long as you maintain a significant distance below the “maximum inflation pressure.” This amount, which is significantly greater than your “recommended tire pressure of 33 psi, Gary,” is noted on each sidewall.
Therefore, in your situation, I’d suggest leaving the tire pressure at 35 or 36 psi. There won’t be any differences in braking, handling, or tire wear.
Additionally, you’ll still have 30 psi or more even if the temperature drops by 50 degrees, keeping your “low pressure warning light off.
There won’t be any harm if the temperature changes in the opposite direction. At the very least, Gary, you’ll get better fuel efficiency and a somewhat firmer butt massage while you’re driving.
Are tires okay at 32 PSI?
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, insufficiently inflating your tires to the correct level will have a detrimental impact on tire wear, vehicle performance, and your maintenance schedule when it comes to replacing them.
Which is preferable, under- or over-inflated tires?
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.
Can you overinflate your car’s tires?
It is not advised to exceed the appropriate tire pressure for a variety of reasons. Premature tire wear is inevitable. The core of the tread portion wears down substantially more quickly than the outer borders of the tire when it is overinflated. They might only last half as long as they usually would because of this.
Is the pressure in 26 tires too low?
The required tire pressure should be found in your vehicle’s user manual or on the tires themselves, even though a psi of 26 is not cause for concern. When a tire’s air pressure is too low, which is often 25% or more below the manufacturer’s recommended pounds per square inch, your TPMS will alert you.
But you shouldn’t wait for the TPMS warning light to turn on before inflating your tires. A trip to the air-filling pumps is typically necessary if your tire pressure is off by more than 10% from the acceptable level.
If tire pressure keeps dropping, you might want to consider calling Jerry for roadside help. Jerry offers you the best roadside assistance available, including towing, lockout service, and a mechanics hotline, for for $50 a year.
