I have tubes fitted to my 408 tyres [16"]
However, the tyre company who fitted the tyres to my refurbished and powder coated wheels said that the internal surfaces of different tyres vary greatly.
From what you say, it could be the internal ridges in the tyres that are causing the wear and punctures to the tubes.
If your tyres are not sealing you may have to check the tyres for airtightness.
