What is the proper pressure to inflate your car tires?

I've got differing answers from different people. My car has tires that say max psi 44 lbs. That's maximum pressure 44 pounds. Should tires normally be inflated to the maximum? Or is maximum just as it sounds, the maximum, not minimum. Some say you should keep them at about 40 pounds to allow for air expansion when driving at highway speeds on hot days. Others say just always keep them at the maximum rating. What's the real answer?|||The tire manufacturer lists the maximum for the tire but doesn't account for the vehicle. Since each vehicle doesn't weigh the same or have the same suspension set up, you can't go by the tire maximum pressure. The correct way is to go by the placard in the drivers door or the car owner's manual.|||I would keep your tires inflated to the maximum. The manufacturer has taken into account driving on hot days. The number listed on the tire is the maximum amount you can have safely.|||In order to get the best gas mileage you need to keep them at 44 lbs. So go with what the recommended pressure is on the tire.|||I run the tires on my Expedition at maximum pressure in order to help my fuel mileage.


All vehicles have a tire pressure placard in the door jamb. It ususlly gives 2 sets of pressures,normal and fully loaded, inflation info should also be in your owners manual. . Always follow manufacturers specs for safety.|||Read your car manual, it will tell you the exact psi. Some cars have higher pressure in the front than in the rear. It isn't that important unless your vehicle is swerving to the left or right when you aren't touching the wheel. That is a usual indicator of low pressure in a tire. Balding on the outside of the tire means over inflation. Balding in the middle of the tire means over inflation. Vibration of the steering wheel means you need your tires balanced. They won't pop if that is what you're worried about. Read your manual for your car, it will tell you what the pressure should be, it isn't always what the tire says it should be.|||You need to safely run your tires a few pounds below the maximum. I have same max. limits on one of my cars and I always run about 41-42 in them. Those people were right who told you to leave some pressure allowance for heat expansion. Trust me on this. The maximum is just that. That is the maximum amount the tire can safely handle under a full capacity load. (Example being four seats filled with passengers, loaded trunk, small trailer towing,etc.) So keep a bit under and make sure they are checked frequently to obtain better fuel mileage also. Should also rotate every 3-5 thousand miles for good even tread wear. Take care!|||Pressure varies. Look on the tire and find out. It will say MAX P.S.I. COLD. Usually between 32 and 45 psi. Check in the morning when tires are ( COLD )|||Never inflate to the maximum shown on the tire sidewall; EVER.





If there is no placard on the doorpost of your car just inflate all 4 tires to 30-32 PSI and you will be fine.|||you should keep it 44 pounds...driving heat will add a pound or to but not enough to mess with anything...if u go under u will not get the best fuel millage for ur car..|||never max 35psi i worked at shadden tire co. 4 15years n thats what we inflate tires to if u over inflate u wear off the ends off your tires n will have to rotate them.also over inflation will not let as much water pass on a rainy day n cause u 2 hydroplane.|||You can't go wrong with 32 psi. Do not run the maximum, it's way too much air unless your car weighs as much as the the tire says it's rated for at the max psi. Everyone always sees the "Max inflation 44 psi" but they never seem to see what follows, "at 1500 lbs" or whatever the weight rating may be for that tire. IE: if the tire says 44 psi at 1500 lbs. that would mean you should run 44 psi if your car weighs 6000 lbs. Does your car weigh 6000 lbs? Not unless it's an F-350 super duty or something of that nature. Look at the weight rating on the tire, then look at the gross vehicle weight on the door placard on your car. It will be way less than the sum of the four tires. While you are looking at the door placard, look at the psi recommendation. It will most likely say something around 28-30 psi. The manufacturers tend to run them a little low because it makes the car ride smoother but you will wear the tires out faster. After all this, you will find that you will want to run your tires right around 32 psi, maybe even 35 but no more than that unless you are carrying sand bags every where you are driving.|||Just look in your owners manual and it will tell you the psi to inflate them to or where a sticker is that says.|||Out of all of the answers I am still surprised at how many people get air pressure wrong. Inflate your tires to what the Vehicle Manufacture recommends.|||You must have a small car. I'd put about 50 in them.
