I get it with the "no spares," they're so rarely used that it might be worth it to save the weight/space/expense.
I drive Jeeps. I've toted around a massive fullsize spare tire and had a Hi-Lift jack on my hood or in the truck bed for something like twelve years. Wheeled some of the Jeeps pretty good. Number of times I've need to use that Hi-Lift on my own rig? Zero. The spare only got put on when it was time to rotate the tires.
In fact, there was a time when I had a "rear tire delete" and left the spare in the garage. Never needed it. Not once.
...and that's great, until you actually need one.
