Ditto bigtoe’s comments and add...
Commercial tires come in 0.5” diameter sizes and do NOT have a safety bead and they carry weight a bit different than our tirres in whole inch diameters.
The safety bead is mostly for run flat and low pressure so that the bead won’t come off the rim.
The pop you hear when the tire mechanic mounts the tire on wheel and 1st air to ‘set the bead’. That is the tire bead running up and over the safety bead (the bump mentioned above) and hits the wheel rim. Also why they soap the tire bead before mounting on the wheel
Very dangerous to mount a whole inch dia tire on a half inch dia wheel.
It will seem to mount and inflate...but it will come off the bead area easily during a hard turn or bump.
To the OP, you can make the switch to 16” dia wheels and tires. It will weigh significantly less than the half inch commercial setup, but will not have the ratings of a half inch dia commercial tire...but...you won’t need that with today’s tire’s.
