Why the fuck is the word shit "censored". What is the point of obfuscating a few pixels yet the word is still visible
Probably to dodge shitty social media OCR censoring
Either OCR censoring or engagement bait for wherever it was originally
people are so consistently mad about this in memes now I'm going to start including it in all the memes I make

Bro I found it of reddit years ago and has been sitting in my meme folder bunkers since then. I don't know who did it
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.
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.
One of life’s pleasures, for me, is getting…
Oh nice, me too!
I might be on the spectrum though
Ah, me too
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"
Hey fellow programmer! This is definitely a thing for me too, it's uncanny how frequently some random tidbit about a piece of architecture that I've tinkered with as a hobby years ago becomes relevant, and I just blurt out to a colleague "oh, do this and that, and it should work".
But on the other hand I have to pause for like 30 seconds up to a full minute before answering when is my kid's birthday, just to make sure I'm not getting it wrong somehow. 😭

it will work as described
Though not always and this is not just mildly infuriating

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.

100 psi = 100 pirsent.
100psi is 6894 hPa for the freedom challenged among us.
neither of those mean anything to me
100 psi
14400 lbf/ft^2 (pounds-force per square foot)
1600 ozf/in^2 (ounces-force per square inch)
689.475729 kPa (kilopascals)

why didn't you say that immediately??

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.
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.

There are two types of friends, this is the second type.
Holy Shπ
If the car doesn't fly, whoever stands by one of those tires most certainly will
Fly straight to heaven
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.
Holy crap!
Omg glad you were ok! New fear unlocked!!
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
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.
270bar pneumatics..... Fuck that
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
Plot twist: That reading is in Bar
