Most cars sold these days don’t include a spare tire (or wheel) anyway; they give you this crappy “donut” thing, which is good enough to get you to the nearest service station and little more.
I was upset when they started providing those donuts instead of a real tire. With the cost of a new car, you would think you would get a real spare.
I've referred to it as a "polio tire" for years. A car that is using one looks deformed, and in need of mechanical attention.
I’ve seen cars rolling along at 75 on the Interstate with those donut spares.
When I needed a spare - I really needed a spare.
But I also carry two big cans of Fix a Flat.
When we lived in Uganda I carried two spares and a patch kit. One trip in N. Uganda I used all my patches and had to resort to “drive 10 km, pump up tire(s). drive 10 km...”. to get back to the mission station. The next morning I found I had three flats on the ground and a flat spare. It took 34 patches to fix those. (LOTS of BIG thorns in Karamoja!)
OTOH, I cannot remember when I have had a flat in the USA. We live on a rough, rocky mountain road. Our Honda CR-V has 160K miles and the “nubs” are still on the spare. The Outback has 230K and I’ve never used the spare.
I could live without a spare in the USA and I’m a “belt AND suspenders” type of guy.
