Hello all. I guess I will step up and be the resident tire expert. There
is no problem running inner tubes in radial tires as long as you use a
radial tube. The tube itself does not have radial construction but is made
of a heavier material. If you were to use a regular(bias-ply) tube in a
radial tire, you would wear out the tube due to the flexing of the radial
tire. Just trying to be of help.
