Years ago, I was in a department store. They had "tire
pressure gages" for $1.99, and next to that was "Radial tire
pressure gage" for $2.99.

Might be the same concept.

If the radial gauge was backward compatible, that would account for the
higher price.

Right.

The bigger problem is getting radial air for the newer style tires.
