A smaller tire can gain some diameter by increasing the pressure. My main trip/tow car, a Grand Cherokee (two seats and A Lot of luggage space, Gets over 22 mpg at 70ish). carries both a full sized spare and a compressor. I also have AAA with 200 mile towing. Other cars mostly have temporary spares. Smaller cars I also carry mats and straps to fasten a road wheel on the trunk lid. CTS does not ever have a place so I carry compressor, slime, and a radial tube with tire irons.
Modern tires have an extra nylon or polyester top ply or cap that dramatically reduces the incidence of tires coming apart.
