    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.

      Massive problem with some older people because that’s how you were supposed to do it with old bias ply tires.

        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.

        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.

          Edit: From what I can gather, “EK3” is a codename for a model and generation of the Civic. The EK3 also started in '96, not '93, so you may have been given the wrong info.

          [This model utilized the same design language as the rest of the Civic range but was actually a hatchback version of the Honda Domani, sharing that car’s platform which was derived from the previous-generation (EG/EH/EJ) Civic.](https://en.m.wikipedia.org/wiki/Honda_Civic_(sixth_generation)

            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

      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

      If you consider that a car weighs hundreds of kilograms but its contact surface with ground is something like 100 squared centimetres, that pressure makes sense

      I work with industrial hydraulics, the forces involved in big gear are truly insane.

      Working pressures is around 270bar…on ~1.4m^2 of cylinders. Millions of kg of force.

      As much as hPa is legitimate, in English speaking contexts I wish we kept to 10^3 prefixes. (Pa, kPa, MPa, GPa etc).

      Like how we keep to nm, μm, mm, m, km. Mostly.

      Or if one really must, atmospheres. Other units are just more of a pain to convert between, like yeah, it’s metric, so it’s not THAT hard, but just nicer in my opinion if it’s consistent intervals.

      Alas, at least I very rarely need to deal with PSI. Only with valve manufacturers using imperial valve coefficients (Cv values), grumble, grumble. They don’t even include the units usually, which to me is heresy. The units are US gallons/min of water at 60 °F per pressure drop of 1 PSI. Like, US engineers have this really stupid habit of not including units in constants and coefficients in some contexts, drives me up the wall.

      Thanks for being the convenient recipient of this metric engineer’s unit rant.

        As far as I know hPa is the preferred unit for air pressure and is used a lot. Usually referring to the air pressure of the atmosphere.

        Also hectometer is used a lot when talking about land measurements. And we don’t mostly keep to mm and m, in my experience cm is the most used and most useful measurement for every day objects.

        All of the different prefixes are valid and are used. It just depends on what context, which one is the most useful. No reason to stick to the 10^3 units, just use them all.

          I should clarify, this is my personal preference, for ease of conversion. I wish we stuck to consistent intervals. They’re all valid, just that I find it very lovely that in industrial/construction we don’t use cm (in Australia)

          But there are so many various pressure units in use, which is a slight inconvenience. Pa, Bar, atm, cm-water, are the ones I’ve come across in actual use so far. (Metric engineering context, RIP US engineers)

          Makes it necessary for me to use a calculator to make sure I’m not messing something up. kPa to mbar: okay *bar/(100 kPa) * 1000 mbar/bar (which I’m now noticing is hPa)

          So in addition to my preference for consistent prefix intervals, let’s also stop using Bar, cm-water, and anything else that’s not Pa. That’d be nice ☺️

        If we take the banana to be 180 grams and the square dishwasher to be 0.36 square meter, that would come to about 140,000 bananas per square dishwasher.

      I find bar more intuitive even if it’s just hPa/1000

      Nearly 7 bar is impressive for any tyres

        Any car tire.

        For road bicycles 7 bar is just “normal”, 8 and above isn’t unheard of.

        A guy once asked if I was crazy when I was pressurizing my hybrid bike to 6 bar, and I just pointed to the sidewall where the rating said 4.5-6.5 bar. The range is wide because the pressure you should use varies depending on what you weigh, and how you want to balance rolling resistance vs comfort.

        And even then the safety margin on bike tires is more than double the max rating, so it’s perfectly safe to go a full bar over if you want.

      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.
