Do you know how to change a flat tire?

Of course

Yeah, it's pretty easy. Might take me a while, but I can definitely do it.

Yep.
Find the 'jacking point' beneath the car nearest to your flat tyre.
Loosen the wheel nuts just enough to make them easier to remove without too much movement of the vehicle.
jack the car up just enough so the flat tyre leaves the road.
Undo bolts and remove wheel.
Replace with spare.
Return wheel nuts and tighten enough to secure wheel.
Lower vehicle safely back to the ground and tighten wheel nuts.
You should always carry chalk or bright yellow crayon in your car.
This way you can mark the damaged wheel to remind you it's no good and needs replacing.
Also a good move if you get stopped by the cops who can actually write you up if you have a faulty 'spare' in your trunk.

though I've never done it, I have ideas through observation.

Yes, have had to change Many flats on a variety of vehicles in a variety of weather conditions

Yes

Took car mecanic in college oil brake tires ya

Yes.

Do you mean take the wheel off the vehicle and put on a new one then yes. If you mean take the tire off the rim and put on a new one then the answer is still yes.

Things I always insisted on back in my driving days--good tires and a good battery. But I've changed a few tires and jump-started a few batteries.

Technically I do. I watched my female cousin change her own flat tire when AAA took forever to show up.

Step one. Handbrake on Step two, car in park or in gear. Step three chock the opposite side wheels. NOW start on the tyre

Yes, though I don't know if I have the strength to actually do it.
