I have changed car/truck/trailer tires quite a bit over 58 years of driving. I don't much anymore, because tires are a lot better than they used to be and I'm not quite as adventurous as I used to be. Last tire I changed was a bicycle tire about two weeks ago. I've changed tires in some gawdawful situations. Blew two tires on one trip with a horse trailer (loaded with 2 horses) one day. No spare, but fortunately a dual axle trailer and only a few miles left to get home. Tied the horses out in the pasture by the roadside and did some swapping around, made it home on one axle. Horses didn't seem to mind.
