G'day Folks :)
Well here's my 2 cents worth, the fitting of tubes to tubless rims would depend mainly on the rim type, I.E. Mags etc, but on standard type steel rims there should be no problem, the Army had fitted tubes to all it's Olympic Steel Treks, and they were on well abused vehicles and rims, if you bend a steel rim that is fitted with a tube you don't loose air pressure, I have run tubes in ALL of my tyres both conventional and radial since the 1950's and can remember that Pirelli recomended that tubes be fitted to all rims when they first released the Centurato, and Michilen released the "X" in the 60's and they were being fitted to rims that sometimes were not even rated as "Safety" rims, I have never blown a tyre that was fitted with tubes, caused by the tube.
cheers.
