Tapers vary. IIIRC Honda’s lug nut tapers (for example) have a convex rounding, and the rim’s stud openings have a corresponding concave taper.
Thank you for the detailed response. For cost reasons, I'd like to find the correct match at a junk yard off a relatively new 23-25 vehicle. I know our 2012 Prius's spare was still quite usable at 12 years because I picked up a nail in 2024 and had to mount the spare! Now the question is to try to determine if any of the cars I listed in my original post matches the requirements for a hub size of 60mm/60.1mm, and an overall tire diameter of approx 26.4". Let's see if Google can be my friend....
After having several flats last year, I won't buy a car without having a spare. The roads are only going to get worse, at least here where I live. Taxes for road and bridge repair has been a flat rate that hasn't changed since the 80's. And in case you haven't noticed, there has been a bit of inflation since then, so the same 40 cents from every gallon doesn't buy as much asphalt and gravel as it used to.
Personally, I prefer my cellphone to carrying a spare. I can either call for help, or locate a tire shop I can limp to within range. At any rate, my days of changing tires is far behind me.
I live in the wrong place for that. We've called tow trucks that take several days to show up. We've taken flat tires to the tire shop to find out the waiting list is so long they won't be able to get to it in a week. And if it wasn't for having satellite phone capability there'd be plenty of places we wouldn't have any cellular service. And while cellular service keeps getting better, towing and mechanic services seem to keep getting worse. It used to be that you could get a tow truck or have a flat fixed on the same day, not days later. If I were to move where things are more convenient, I'd move to where cars aren't necessary. This whole "everybody needs a car" thing is overrated and just plain stupid.
I just got over a snowy pass with tire chain law in effect. If people can't change a spare tire or put on tire chains, should they really be driving?
No, but they aren't all the same size and the larger ones can present an obstacle with some aftermarket options. Lots of women drive daily with no ill effect. I knew a 93 year old fellow with a bad hip replacement and a walker who still liked driving. There's a pretty large difference between the population who can safely lack up a couple of tons of car, lift and handle a 40 pound wheel into and out of a trunk and loosen and tighten five huts to 80 or 90 foot pounds. Of course, there are no people whose options become more numerous when they decide to drive without a spare.
