One of my previous cars came with no spare but “run flat” tires (might be named something else). Basically they have strong sidewalls that do not collapse even without pressure. You can ride on them at much slower speeds to get to a tire shop. Loved those. My later cars both had no spares neither an emergency solution like the previous one had. I used a foam tire sealer once, worked wonders on a small puncture. Couple weeks ago I managed to completely fuck up a tire on my volvo with no spare. Had to call assistance number, they sent a tow truck.. Spent half a day sorting it out.
