GMC began offering tubeless in the mid 1950's. My father was selling tires at that time, and it was common for people to install a tube for "safety" reasons. Usually they had trouble with the tubes folding or being pinched which caused a flat. I have owned 18 wheelers for 60 years ago. The first thing I did when I bought a used truck in 1964 was switch to tubeless tires. Salvage yards were practically giving the wheels away because no one wanted them. I ran tubeless bias until tubeless radials came out. And I have never had the urge to use a tube unless I just couldn't get a one piece wheel. I even have tubeless tires on 50 and 60 year old farm tractors. If the wheel is pitted, it will rub a hole in the tube. Same goes for the hole for the stem. If your wheels are in good shape, I wouldn't even think about tubes. And I think they are all made in China now anyway.
