My $100 lesson on changing a flat tire

So over the weekend I'm walking to my car to go grocery shopping and I notice one of the tires is flat. I had never had to change a flat on my own and I assumed the concept was simple: jack up car, remove bolts, remove wheel, repeat steps in reverse with spare.

I was wrong in almost every aspect. For my vehicle it wasn't that simple. I noticed that 1 of the 5 bolts on the wheel was different from the others. Regardless I jacked up the car anyway and got to work. The wrench included in the back only fit the one bolt that was different. Being an idiot, I tried loosening that one bolt anyway. Wouldn't budge, and on top of that the wheel would move with any sort of motion. Fine, I stuck it in gear and it stopped moving but the whole car would still move, teetering precariously on the tiny jack that was included in the car. I wasn't sure if I was rotating the right direction so I check the manual. First thing the manual said was to loosen the bolts before jacking up the car. Whoops. Lowered the jack. Second "remove the bolt caps". That would explain the other 4 bolts, they still had the cap on. The manual also mentioned using a small tool to remove these caps but it wasn't in the toolset in the car. Fuck. I try prying it with a screwdriver, nothing.

I talk to the garage attendant who says he has an air pump, but my car is on the 3rd level and it's on the ground floor. He suggests to "drive slowly" and so I do. Important thing to note here: if your car is suddenly flat, it's flat for a reason, DO NOT FUCKING TRY TO RE-INFLATE IT! So my car waddles down to the ground floor and he starts pumping air into it. I tell him to please pump it to 36psi since I know that's the pressure for my tires. He tops it off a little bit, looking at the meter and BAM! Sidewall blows up right in his face. This was in a garage so it reverberated throughout. After "mawp"ing for a few seconds until the ringing subsided, I hear him saying "oh shit, oh shit! you said 36 psi!".

At this point I say fuck it and reach out to a tow truck to see if they had the tool to remove these bolts. Find one, said he'll be there in 20 minutes. An hour later he comes, takes a look at the bolts and comes back with a drill. He removes each of the covers and puts them on the ground. I notice immediately that when they hit the ground it didn't have that heft I was expecting. I inspect one of them. Fucking plastic. These silver colored "bolts" were just plastic caps. Needless to say he replaces my whole tire in about 5 minutes and says that it will be $125. I tell him that all I needed were to have those covers removed in the first place and then he agreed to $100 fine ($118 with tax) but it included a much needed lesson in car maintenance.

tl;dr: Forget what you think you know about car maintenance if you've never actually performed it yourself. You don't know jack shit.
 
I once had the unfortunate bad luck of getting a flat tire twice in a week. I will never need reminders of the process again, lol.

Not surprised to see the tip about loosening the bolts before lifting the car. That's the number 1 thing to keep in mind imo.
 
Roadside assistance has made me less of a man, but it's also one less thing I can fuck up. Except when I forget to make the monthly payment to AAA.
 
Also a lot of manufacturers are opting to instead use a spray compound instead of equipping spare tires these days to increase mpg.

What are your thoughts on that?

Yep, I've fucked this up before. Spent something like 30 minutes trying to turn them without them budging, finally called someone to take care of it.

I wouldn't have given you that discount, OP. Dude had to come out and do the job, you should pay him for it.
 
There's nothing wrong with re-inflating a flat tire... I had a tire that had a slow leak in it, and one day came out of work to a completely flat tire. I filled it up with a travel compressor to drive home and then brought it to the shop the next day to have it fixed.
 
Holy fuck. Fail on multiple levels.

Btw you can totally inflate a tire if it's flat, just not over... are you sure your car and tires are rated at 36psi? From what I know it's the vehicle that determines psi levels, not the tire. There is a placard usually somewhere on the door frame.
More tire changing tips:
chock your wheels (put a block or something behind the wheels)

when putting wheel back on, put the bolts on snuggly, then lower the car and tighten bolts. Take it to a shop to get it properly torqued immediately afterwards.
 
What the fuck dude you did some really dumb shit right there.

You almost killed him and then argued the cost down 20 bucks?!!?!?!

Chock.

nah, 2 different people: garage attendant was operating the pump, and the tow truck guy who came was the one who charged me. Garage dude was ok, just rattled.

The pressure rating I was referencing was indeed on the sticker inside the car. I have reinflated my tires before without blowing out my eardrums.
 
what the fuck is wrong with you? you nearly got him killed and you tried to haggle his ass down?

also, reinflating a flat once is fine if the damage isn't in the sidewall. if the damage is in the sidewall, don't reinflate it. it's common sense

Different people, but still.

How did the tire blow if it wasn't even up to the recommended psi? Is that possible?
 
Hmmm I'll need to keep the "loosen bolts before jacking car up" tip in mind for the future.

I've had to change a flat one time in my life and I remember it taking a lot of force to undo the bolts. Luckily I was able to do it, and the rest of the process went like OP's original thoughts. Felt pretty good about myself afterwards too, not being a car guy or gear head of any sort.

Don't know what sort of crazy car you've got, OP, but I'm glad my Camry doesn't try to make things fancy and whatnot.

he haggled with the tow truck guy, not the garage attendant.

Hope you apologized to the garage attendant, god damn.

yes, if the damage is in the sidewall, it can rupture well before the recommended PSI

a lot of time when i worked at a bodyshop, people would come in with these fucking tires that had been grated down to the wires, had a chunk taken out of the sidewall, or straight up had tried to reinflate it and caused these HUGE air pockets/bubbles. it's fucked up, dangerous, and nothing anyone should ever try to do if they're not educated about it enough. i had someone have to quit with permanent hearing loss because of an overinflated tire with a bad sidewall exploding. people die all the time because of this stuff.

ah, alright, missed that.

I had inspected the sidewall and didn't see anything. I felt that I shouldn't have even tried reinflating at all.
 
I guess I'm glad my dad gave me this whole lesson before I even got my own car. The one thing he didn't tell me, though, was that sometimes the wheel will stick to the axle be an absolute bastard to get off. I've had to drive on a few flats because the wheel wouldn't come off after I had removed the bolts. Turns out, putting your back to the car and giving the wheel a swift stomp can sometimes do the trick.

When he drove it down the levels while flat he probably really damaged the sidewall, they aren't supposed to be driven on, and the rim can easily damage them.
 
So the guy inflating the tire, did he overinflate? Your state he said "Oh shit you said 36 psi!" If he did, then that is on him so don't feel too bad about it. Unless there is a slash in the sidewall, it should not blow at 36 psi.


Edit : per the above posts, I forgot that he drove on a flat. Yeah, that is not ok.

you shouldn't have. if you're not confident, don't touch it. by driving any bit with a flat tire, THIS happens. it's unpatchable and means you have to scrap the tire.

all of that is rubber from the damage being amplified thanks to driving on a flat, reinflated or not. i would never recommend anyone drive on a flat, even if they're using runflats.

Nah its worse than that, two different people, he nearly killed the dude and DIDNT GIVE HIM A DIME! Instead he stiffed the dude who knew what he was doing.

Yes yes let's blame the garage attendant who was kind enough to help and follow OP's directions.
 
It's written on the door.

nearly every vehicle has a placard inside the driver's door with recommended PSI among other information.

Right, and typically people who know that usually know how to inflate own tires.

I don't know. I think it's strange for a car not equipped with an inflator. If you don't have one, go out and buy one now.

Don't you drivers check your tire pressures monthly?
 
Fortunately my breakdown cover includes them coming out to put my spare wheel on for me when I needed it a few months ago.

Because like hell do I have any idea how to do it for myself.

you don't need to buy an inflator. you need a jack and a spare - and to be competent about making sure it's at a decent PSI a few times a year in case of emergency. barely anyone has an inflator.

Knowing how to inflate the tire wasn't the issue, and it sounds like the OP does know how.

Also in my experience most people do not have a pump in their car.

This has nothing to do with the OP knowing how to inflate a tire...
 
You weaked the side wall by driving on the flat tire. Thats why the side wall blew out. Its dangerous to inflate a flat that has been drive on. The garage attendant should have known this.

from what the OP says, he didn't tell him it was a flat that he had been driving on a flat, only that he had a tire with less PSI than the others, which is standard fair

Dont follow the PSI on the tire. Follow the guideline by the driver side door.

also, this
