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.
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.
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. 😭
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.
