Does the sidewall information say "tubeless" anywhere? The construction is very different between tube type and tubeless tires, which would be much more of a concern for me than possible seep leaks from rivets. Epoxy-type paint, or even 2-part primer inside the rim after a good bead blast should handle anything but a severely loose rivet.
