    Once my roommate punctured one of my tires and I went to a gas station and filled it up. Must have been one of my first times doing it ever. As I got back on the highway my car finally showed the pressure, it read 73….

      Don’t feel bad … I drove down the road once in my old truck and started feeling a terrible shaking … I drove for a while hoping it would go away but it got worse. I finally pulled over and had a look at front passenger side tire … a bulge was sticking out of it like a giant bruise and once the tire stopped moving, the bulge grew ten sizes and as soon as I realized what it was, I turned away and the thing exploded!

      Always check your tires.

    I’ve stopped a half dozen people from doing something like this… Every single one of them was filling up to the maximum pressure listed on the sidewall.

    The sidewall pressure is only the correct pressure at the maximum load on the tire. The maximum rated load on the tire is often nearly twice the vehicle’s maximum weight rating, so the sidewall pressure is never the correct pressure for your vehicle.

    The correct pressure for each tire on your vehicle is listed on a tag on the driver’s door, or door frame.

      Jup.

      Cars actually come with manuals that explain this stuff.

      Reading is a lost art.

        Honestly Ive looked all over for my car manual but I cant find it anywhere on the internet. My car is a 1993 Honda Civic EK3 which I got second (more likely 5th or 10th) hand. The earliest model’s manual I can find online is the 1995 model. Do you know a good site that might have the owners manual for my model?

          It should normally be on a label stuck to the left B-pillar, below the latch for the driver-side door (that little loop thingy the door grabs onto when closed)

          ManualsLib also has the original manual where it’s listed on pg. 143.

            Whelp, turns out my government employees strike again! Turns out the whole registration is wrong. Its a 1993 but its registered as an EK3. No idea what might have happened there. Anyway, thanks for the info :D

        I’m with you, I’m the one who read my wife’s car manual.

        One of life’s pleasures, for me, is getting home with a shiny new thing and going over the manual and trying out the features, and of course it will work as described, and somehow that’s very satisfying.

        I might be on the spectrum though, my experience is that people find that weird and nobody bothers to read manuals.

          it will work as described

          Though not always and this is not just mildly infuriating

            Same, but in my line of work (programmer) it makes me look like a damn savant. “How did you know how to do X?” “Oh, I vaguely remembered something from reading the API docs 2 years ago so I just went and looked it up again”

      Don’t forget also that tire pressure increases with temperature. You’re pressure will be higher if the weather is warmer, and will actually increase as you drive. A 30 mile drive could see a 4-5 psi increase.

    I know this is obvious but it boggles my mind how each square inch of that tire has almost 100lbs of force pushing on it

    Just realizing now why hydraulics are so strong, a 6 inch squared piston at 100 psi is 600 pounds of force

    meanwhile I’m sketched out by the tires on my uncles old road bike that say max 90 psi wheras mine say like 20 or so.

        Ok so that’s what the backup tire says 60psi.

        When I first saw it, I thought that it has to be wrong and I’m looking at the wrong number.

          When I saw it the first time, before I understood how it worked, I thought “surely this is just for long-term storage purposes and I would need to bleed some pressure if I wanted to drive on it”

    These stupid sensors don’t do anything useful, they’re just a needlessly excessive expense when they need to be replaced.
