    I'm completely new on using tire inflators. So what does the manufacturer mean when it says "150 psi"? Can I only use up to 150 psi and then it will turn off? If so, then when can I start using it again?

    That means it will explode if you go over 150psi

    Thanks for all the cute comments. One guy tries to be funny and the rest tries to follow.

    Can someone explain the max 150 psi thing? Is it the total of all tires cannot exceed 150 psi or just one tire?

    You seem to have misunderstood what psi is.

    It's a measure of pressure "Pounds per Square Inch" not volume.

    The rating is the maximum pressure that fitting can hold.

    Not to worry, car and truck tires are fully inflated at much lower pressures.

    it could also mean the compressor is only strong enough to reach 150psi. especially if its a cheap cigarette outlet inflator...

    total of one tire cannot exceed 150psi.

    150psi is where your tire becomes an over inflated balloon (thats what they mean by your tire becomes a bomb). the walls stiffen up, you will go faster, you will probably get better gas mileage, but braking won't be so safe. our door jams say to keep the PSI at 29. the dealer ship set mine to 35psi so i guess 29-35 is safe. a cold tire is a tire that hasn't been driven with tires get warm when used and the air inside expands so you wouldn't have a true psi reading so check it in the morning right before your drive.

    actually, the tire pressure cannot exceed 50psi. Even my Load E range tires have a max pressure rating of 80PSI.

    I was being serious man!
    Your tires say on the side what the max PSI is, Maybe you should seek a ASE certified mechanic to help you with this highly volatile situation.
    That is sarcasm by the way. :D

    Max means just that, Maximum.
    –noun 1. the greatest quantity or amount possible, assignable, allowable, etc.

    2. the highest amount, value, or degree attained or recorded.

    3. an upper limit allowed or allowable by law or regulation.

    Come on now. Don't start a fit. Look at your question. You are asking what maximum means. Expect a few dumb answers for a dumb question.

    where have you ever seen a 150psi spec for a passenger car tire???

    the pressure on the door is set by the factory for optimal driving and handling on stock tires. if you go over that psi you are fine, as long as you dont exceed the tires cold pressure limit. If I only had 29psi in my load e tires it would be all over the road. Way too soft. you need to use good judgment and/or do a chalk test.

    regardless, this is about the "inflater" or better known as "air compressor" max rating of 150PSI. which means it only has the strength to inflate anything up to 150PSI.

    I'm referring to the tire inflator stating 150 psi max and Yoytoda answered the question. Thank you Yoytoda.

    Thanks to all those who tried to help. Even though my question was answered, this has to be the most worthless section on TW.

    Hey no problem. Anytime you need a stupid answer feel free to post. You will get the same result anywhere on the site and even from some mods.

    oh snaps, someone got sand in their snatch. stupid response on dumbass vague question. with 100s of inflators, you think there is one answer as to what might happen??? one might go boom, one can melt, one can let you time travel. youre the person that warning labels are meant for.
