Is 40 psi good for tires?
Specifically, the level of 40 psi can be suitable for passenger cars or sports cars. But this is too high for small cars with a recommendation below 35 psi, while 40 psi is too low for large trucks. The recommended level for the tires of famous sports cars and passenger cars is between 32 -40 psi.
How do I know what PSI to put my tires at?
To find the correct PSI for your tires, you can either look inside your car door or open your car's manual and look it up; you can usually find it under “tire maintenance”. Most cars and trucks will fall between 27 and 35 PSI, unless you're using a commercial vehicle, because the PSI for those tires varies widely.
Should tires be filled to max PSI?
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.
Is 50 PSI a good tire pressure?
340 kPa ( 50 PSI)”. This means that the tire will safely carry up to 1477 lbs. and can be safely inflated up to 300 kPa (Kilopascal) or 50 psi (pounds per square inch). Often the vehicle manufacturer will specify a slightly lower pressure on the door jamb sticker for purposes of ride comfort and handling performance.
How often should you check tire pressure with nitrogen?
Using Nitrogen does not reduce the need to check tire pressure frequently (at least once a month).
Why is tire pressure important?
It is vital to the safety of a driver, as well as the goods they transport. And depending on the temperature, work and load conditions, there is only one. It's tire pressure.
What to do if tire is checked in warm weather?
In all cases, comply with local regulations and laws. Use an accurate, calibrated pressure gauge and handle with care. If a tire checked in warm conditions has a lower pressure than recommended, the tire must be disassembled and checked in accordance of safety instructions.
What happens if you have insufficient tire pressure?
Insufficient tire pressure leads to an abnormal rise in the operating temperature and may cause deterioration of internal parts . This deterioration is irreversible and may cause the tire failure with rapid air loss. Consequences of driving with insufficient tire pressure may not be immediately visible and may become apparent even after an issue has been corrected.
How long does it take for tire pressure to be checked?
Tire air pressure on the same axle should normally be of the same pressure (depending on tire size). Tire pressure must be checked 24 hours after installation and must not be more than 5 % lower than the original pressure. Follow tire pressure recommended by the vehicle manufacturer or manufacturer of your tires.
How to weigh a truck?
HOW TO WEIGH YOUR TRUCK. Be sure to weigh your vehicles, fully loaded, on a scale. Each axle, front and rear, and trailer must be weighed separately. Actual gross axle weights should be compared with the manufacturer's tire data book to determine the inflation pressure required. The load carried by each individual front axle tire should be noted.
Is air pressure important for tires?
Air pressure is an essential element for properly functioning tires, enabling passengers and/or the load to be carried in a way that is: However, from various tests and inspections facilitated by MICHELIN, tire pressure often appears to be one of the least monitored maintenance issues.
What is Michelin pressure tire?

What is the maximum pressure on a passenger tire?
Extra Load tires of the same size will typically have the same load capacity at the same pressure as the Standard Load tire. However, they have added load capacity above certain pressures. Light and Standard Load tires have a maximum capacity pressure rating of 35-36 psi and Extra load tires have a maximum capacity pressure rating of 41-42 psi. The maximum allowed pressure listed on a tire's sidewall can be higher however. Some tires list 44 psi and many higher speed tires will list 50-51 psi. This added pressure does nothing for load capacity. Pressures above 35-36 psi for SL tires and 41-42 psi for XL tires will not increase the load capacity of the tire. Even if you put 50 psi in an SL tire the load capacity will remain what it is at 36 psi for the higher pressure levels. Adding tire pressure above maximum load capacity is used mostly for high speed situations. A tires air pressure is increased to reduce tire deflection for the increase in rotations per second compared to typically city/highway use.
Where is tire pressure listed on a car?
If you are not changing the tire size from the original size that came on the vehicle, then the recommended tire pressure is listed on the vehicle door jamb or door.
How to determine tire load capacity?
Listed inside the driver's side door jamb of your vehicle there will be the originally installed tire size, load rating, and tire pressure for the front and rear tires. The size and pressure have been engineered specifically by the manufacturer for correct load capacity and will typically render the best results for tire wear and ride quality. Tire load capacity is directly related to air pressure in the tires. As tire pressure goes up or down, so does the load capacity of the tire. Too much air can wear the tires unevenly in the center and can create a wondering effect on the vehicle's handling. Too little air can wear the tires unevenly on the outer edges and will reduce the tires load capacity below the engineered level.
What happens when you change tire size?
Changing tire sizes typically brings a change in tire load rating, which may require the new tire's air pressure to be altered to achieve the original tire's load capacity. One way to do this, is to reference general load inflation charts that list tire size load ratings at each psi and set the new tire's pressure to match ...
What is a P-Metric passenger tire?
With metric passenger tires there are actually two types, Metric and P-Metric. You've probably seen a 'P' in front of some of the tire sizes you've looked at. This actually designates a different size than the same tire size without the 'P' designation. They are very similar and typically interchangeable.
What size tires are used in a light truck?
actually come equipped with Passenger rated tires on them. As opposed to an LT265/70R 17, it will usually be either a P265/70R17 or just 265/70R16. This is because not only are they lighter weight and provide a softer ride, but their load carrying and towing limiters such as suspension ability, don't exceed the capability of the comparable Passenger rated tire. Also despite what many might think, Passenger rated tires can actually have higher load carrying capacities at the same pressure as the LT version in the same tire size. The LT tire will generally have a higher maximum load capacity, but it takes a higher pressure to achieve the same load capacity.
Where to find tire type on vehicle?
Reference your vehicles placard inside of your driver's side door jamb. Be sure to read it closely including any tire size prefix or suffix such as a 'P' or 'LT'. Select the correct 'Tire Type' from the drop down, then enter your OEM tire size, load rating, and pressure listed on the card.
