i own a repair shop,and no ,,what they mean is you should never put no more than 40 pounds in them,id always run them around 32-35 pounds per tire,this way they will have room to expand when they heat up,they just mean to never run over that much in them,if you put that much in them there going to ride really bad,and hit chug holes really hard,,but id run at least 35 to be safe ,good luck i hope this help,s.

DO NOT INFLATE TO 40 POUNDS WHEN COLD!
That is the absolute MAXIMUM pressure. The MOST you should ever put in.
It is best to check tires when cold before driving and remember as the weather cools the tire pressure will go down a bit. As tires heat up the pressure increases and that is one way of protecting the tire plus it is a natural occurence when heating anything.
Check for a sticker inside the door of the drivers side. It most likely will recommend 32 - 35 pounds.
I tend to run about two pounds difference if the vehicle has the majority of weight at one end.
Example, a Dodge Caravan or most any minivan, or front drive car has the majority of the weight in front so I run 35 in the front tires and 32 in the back unless I have a full lload of people or cargo then it will be 35 all around. A tire inflated harder than necessary will wear out in the very center before the rest of the tire has worn.
And I rotate them every 6,000 miles to even out the wear.

No don't put in 40 psi. You should inflate your tires to a max of 32 psi as that is the normal range for most tires.

General consensus is 36 psi for passenger cars. Tires will gain or loose pressure as the temperature fluctuates. Also, radial tires are meant to be a little soft.

normally what the tire manufatruer puts on the tire is the maximum amount of air you should put in it.
About 5 lbs below this is acctptable for a good ride. So if it says 40 lbs then 35 is good....don't go below this as it will cause excessive tire wear.
Hope I helped you

Depends on the weight of the car. if its a compact car 30psi is good if any larger adjust up to 35 psi. you want to have the bottom of the tire flat to the pavement. too much air and only the center or the tread will touch and it will wear in the center. Too litttle air and it will bow in the middle and the edges will wear prematurly. also too much air will give you a rough ride.

look on the inside of the drivers door for a factory decal that states what the tire pressure for that car should be. adjust tire pressure when tires are cold---sitting for at least 4 hours or driven less than 1 mile.
