The Park Tool PTS-1 Tire Seating Pliers are designed to quickly and easily "seat" stubborn tires. During inflation, tire beads often slip below the rim edge and are difficult to pull out. Simply place the non-slip jaws on the tire and lift out.
The Park Tool Tire Seater adjusts to various tire widths, and it's chrome-plated with vinyl coated handles for comfort.
Instructions: To use, simply place the non-slip jaws on the tire and lift out.

Works good to dislodge a tight tubeless tire seal from rim edge, and also helps grip the tire when you need to position it over the valve to get tire aired up. I have arthitis so this really helps. Only minus is the handles are a bit clumsy, and you need to be careful about scratching a carbon rim.
I put this on my Christmas list in desperation. I've been changing tires for 45 years, but lately, particularly with the tight-fitting tubeless gravel tires (which I'm still using tubes for), I've had difficulty getting the bead to seat properly. The bead gets stuck down in the rim's center channel and won't pop into place, even with considerable overpressure and plenty of talc on the bead.
So I tried these on some new 50mm gravel tires. With the tires at about 30psi, I was amazed at how easily these could move the bead into place. The griptape inside the jaws works really well, and didn't scar the (tan) sidewalls. Looks like it will work fine with narrow tires also due to its wide adjustability.
The only downside is that by their nature they don't lay very flat, so you need a deep drawer in the tool chest to hold these. A small price to pay.
