I hate doing it, especially in sub-zero temperatures, but I can and have done it many times.
When I had my first car (1977 or so), I could buy ‘recap’ tires for my VW bug for $10 each. They were not the best of tires. One week, I changed four flats! 
I quickly learned to carry a length of small-diameter metal pipe in my vehicle, to
loosen those stubborn bolts.
I’ve done it several times, and it always seems to be in the worst conditions.
- on the narrow shoulder of the interstate
- in a downpour at night (no umbrella)
- in the freezing/slushy cold
- in the freezing cold, at night (no gloves or flashlight)
I hope I didn’t come off as dismissive of women in my earlier post. As I said, I was surprised that my sister thought herself unable to change the tire because she is generally very competent and independent. On practical stuff she’s probably more generally competent than me; I’m more likely to all her for advice on a plumbing issue than the reverse, for instance.
Is that how those things work? I’ve changed my fair share of tires on the roadside (in the trunk or attached to the rear of the vehicle) but always wondered if they really expected you to climb underneath certain vehicles to get at those bottom mounted spares. That’s gotta be real fun in slush and snow.
My first car had front end problems, chewed through tires left and right. I became very proficient at changing tires. I’ve changed to donuts on the side of the highway in 0F weather after I blew a tire, I’ve changed tires on every vehicle owned my my sister, my mother, and I’ve had to change tires for my nephew who had no idea what he was doing. Then again, he thought transmission fluid was oil…
So yeah. I know what I’m doing.
I hate changing flat tires but I’ve done so many times and will volunteer to help people I see with flat tires.
I keep a container of Fix a Flat stuff and A plug kit in my vehicles. The Fix a Flat is usually my first go to so I can drive to a shop and let them deal with it or get to a safe/dry place to change the tire.
Change a flat? Pfft! Cake. Or maybe I’ll just install a plug, air and GO!
Hell, I mount my own tires, by hand. With 10 cars around the yard, I save hundreds.
Since I own a Jeep, you would be amazed at the road-side repair skills I’ve had to master.
Yes, I can do it, and have done it. It was one of my prerequisites, too, for my dad, for me to get behind the wheel.
However, in any kind of inclement weather, the lug nuts are really hard to get off, even if you stand on the doodad. And women’s clothes, etc.
The wonderful thing is, that though I’ve had flat tires on a few occasions and only ever had to change my own once. Guys will automatically offer to fix it, and they won’t take money, and they’ll do it with a smile on their faces. It’s one of the [many] times I really love the opposite sex and love being a girl - I don’t ask anyone to do it, but if they offer, I try and help and be as grateful as is possible and appropriate.
What you do in the privacy of your bedroom is none of my business. 
There’s really not much to it. You just have to remember to do the initial loosening of the lug nuts before you jack the car up, and do the final tightening of them after the car is back on the ground.
Unless your wheel is stuck to the hub. The last two cars I changed tires on (my Mazda 3 and my SO’s Ford Focus) the back wheel was impossible to get off the hub. The first time I called a local guy to do it for me, after spending two hours trying every possible way to get the damned thing off. He used a sledgehammer. So, the second time, I bought a sledgehammer and did it myself. At least now I have a sledgehammer in the trunk of my car should I come across this problem again. And, yes, I tried all the tricks of loosening the nuts, driving the car straight up and down several times to loosen it off the hub.
Well, there’s brute strength to be considered, as I wrote upthread. My stepdaughter found herself unequal to the task when my cousin tried to teach her. She just didn’t have the mass to put into it.
Done it several times, more than I care to count.
All things considered, I will say that it’s easiest with a lift and an air wrench, but I’ve done it many times with a jack and a tire iron, and on a couple of memorable occasions without a jack or a tire iron (I don’t recommend that procedure).
My mom taught me to kick them loose with my feet (obviously you loosen and tighten the lug nuts while the car is on the ground, not up on the jack). You put the tire iron snugly on the nut so it’s kickable, then kick it (gently) until it’s loose. I’ve gotten extremely tight nuts off that way (no double entendre intended 
) - our legs are plenty strong enough for this task. You also want to kick the nuts back on so they’re properly tight (after the car is back on the ground again). I’ve changed my share of flats in my life.
That said, I’ll call AAA too now (well, CAA - AAA probably won’t drive that far). It’s what I pay them for.
I have always been baffled by this, ever since I was eight and went with my dad to change a flat tyre on my school teachers car. How could a TEACHER, an educated man not be able to change a tyre? (I was eight remember)
Then, years later, a flat-mate sat for an hour waiting for the RAC to come and change a tyre on a pissy little Toyota Yaris. He didnt even keep a jack in the car, threw it away, said he wouldn’t use it.
Maybe I am just a independant sort, but come on. I believe its a worrying thing if people don’t KNOW how to change a flat tyre. Sure, sometimes you can’t do it, if a mechanic has welded the wheel nuts on with an air gun, sometimes no amount of leverage will move them, but at least bloody well know HOW to do it. You might well need to know sometime, AA be damned.
This. The only time I’ll change it myself is if we Back of Beyond and it would take Auto Club too long to get there.
To be fair to me, it’s been under 20 degrees here for a couple weeks and there’s about 2 feet of snow on the ground and growing. Changing a tire on a bright sunny day on the wide shoulder of a well-lit highway is the furthest thing from my mind.
Hell yeah I’ll wait that long, and then some.
…I replaced a spare, was in the last century, and it was a fully-inflated, full sized tire, not a donut, but yeah, I can handle it.
Q
I have a AAA card, but I go ahead and change my own tire since I also have a man card I’d like to hold on to.
Actually, if I’m dressed up real purty, like in a suit or tux, I’ll go ahead and call AAA since I don’t want to get my fancy clothes all greasy. But other than that, yeah, I’ll do it myself.
