Which Tube For A Tube-Type IRC TR-011?

I have a Tube-Type IRC TR-011 tire ordered to replace the very old, cracking, and worn Dunlop on my 1974 TY250 project. Do most people run a "regular thickness" inner tube, or the thicker (and heavier) 3mm/"heavy duty" tubes? I don't like the weight of the heavier tubes, but hate pinch flats even worse, where I'd suppose the thicker tubes might be better in that department.

I'll be running 2 rim locks. What is the reasonable tire pressure range for a tubed tire like this?

Sorry for this question, but the only other experience I've had with Trials tires was on my 2010 Gas Gas 280, which was the tubless rear, and a Pirelli MT-43/Nuetech TUBliss on my old KTM 300.

Thanks,

Jimmie
