It makes sense- anything that punctures the tire has an additional thickness of the second inner tube to work through before it releases the pressure. There are also “puncture resistant” inner tubes that are simply thicker rubber.

As above, there are “tire liners” that are tough polyurethane strips that fit between the inner tube and tire. I’ve had some success with the “Mr. Tuffy” brand liners. They can be a little tricky to mount- I inflated the bare inner tube enough to hold it in place before mounting one bead of the tire, then carefully deflating it while prying the other bead on the rim.

The Mr. Tuffies were good enough to keep riding even with large glass cuts in the tire- just a slight bump as the exposed Tuffy hit the ground.

I have not yet tried tubeless. Maybe next year.
