Here is what I've been told in the past, might or might not be correct
1) A radial flexes too much at the junction of the sidewall and tread and
the patch will not stick.
2) Running a tube inside of a tubeless tire may cause the assembly to run
hotter than it should which could be dangerous or detrimental to the tire.
You have to decide from there, but a 6 year old tire is already less safe
than it should be because the rubber in the tread is getting harder than it
should be and its traction is reduced.
